Akdeniz, Esra
Krämer, Thomas
In the first part of the webinar, a brief overview of the CESSDA EuroQuestionBank (EQB) project was given. Authors presented the current User Interface. They demonstrate how the EuroQuestionBank helps researchers find, compare and download questions as well as question-related and study-related information. The second half of the webinar might be of particular interest to developers and metadata providers in- or outside of the CESSDA community. The EQB architecture and the purpose of the components were presented. Introduction of the requirements for metadata providers that plan to supply their metadata to EQB was made
 Okay, hello everyone and welcome to today's webinar, the Chester Eurea Question Bank, Search, Find and Reuse Questionnaire Items from Social Scientific Research. First of all, we would like to introduce ourselves. My name is Esra Akdenes and I work at the Data Archive at GESIS, Leibniz Institute for the Social Sciences in Germany. And I'm the project manager of the Chester Eurea Question Bank project and I'm mainly responsible for the metadata, the content and the communication with our service providers. Hello, my name is Thomas Kremmer, I'm a colleague from Esra at GESIS in Cologne and I joined the EQB project in September and my responsibilities within others are the user interface and partly the indexing of the metadata. Thank you. Before we start, I would like you to know that you are currently all muted but you can post questions to the chat box at any time and we'll be answering questions at the end of the session and if we don't get to your question during today's webinar, we will follow up with you afterwards. And today's webinar will be available after the live session. If you're interested in providing it to your colleagues, you will be notified via email when and where the slides and the recording are available. So let's get started. This webinar is divided into five parts. In the first part, we will give a brief overview of the Chester EQB project and we'll introduce the idea behind the Europeanwide Question Bank. In the second part, the current user interface will be presented. We will demonstrate how the European Question Bank helps users find, compare and download questions as well as question-related and study-related information. In the third part of the webinar, we will present the EQB architecture and the purpose of the components and we will also introduce the requirements for metadata providers and developers who are interested in supplying their metadata to EQB. In the fourth section, we will briefly summarize everything you need to know and we will end our webinar with answering your questions. So first of all, I would like to introduce the project. The Chester Eurequestion Bank project started in 2016 and is funded by Chester. Chester stands for Consortium of European Social Science Data Archives. It is an alliance of social science data archives of currently 20 member countries and in the EQB project, we are currently 10 Chester Service Providers working on EQB and GASIS has the lead of the project and we are responsible for the project management and for the technical development of EQB. So Chester creates and runs services for the social sciences and one of them is the Eur question bank, which is currently under development. So why is it necessary to develop a European-wide question bank and what are the benefits of it? As some of you might know, existing question data banks for social sciences mainly operate on the national level, meaning that they only include questions from surveys that have been conducted within their own countries. The disadvantage of this is that this limits the pool of available questions for users. The Eur question bank will be a solution that has been envisioned for many years. But was never implemented so far. It will link existing question data banks and will offer a single point of entry for survey questions from many service providers. So EQB will be a cross-national question bank with a central search facility across many Chester survey holdings and hopefully beyond. So users will have access to many questions, question-related information and study information within one application from several European countries. So now I will introduce this application and will show how users can use this application to search, compare and download questions. Here you see the first page of the current prototype. So EQB is a search engine that will enable users to search survey questions together with a study-related information and documentation. So let's start with the search. This is a result page which you get when you type in a term into the search box. Following use case, I'm a researcher and I would like to design a questionnaire on the topic employment. And I'm not sure how I should formulate my questions. But I know that the term job should appear in the question text. So I click, so I type in job and start the search. Before I look into my results, I can narrow my search term by question text, response categories, study titles and pre and post question text. So here the system browsers the term job in all available question text and all questions containing the term job and the metadata will be displayed. In addition, the search can be supported by filters, meaning the search can be narrowed down by serials, collection year, country, language and mode of collection. So the filters will help you to search more precisely and to refine your search query. For example, you search for the term job and tick question texts and select the country filter for Sweden. This will display questions containing the word job in the question text for data collected in Sweden. Before setting filters, you will see all available questions and some additional information for each question. A detailed question view, the response categories, the study in which the question appeared and a drop down to select different language versions. So the user can switch between different language translations of a question by selecting a language. The user can also view the response categories of the question and the user can see more question related information by clicking on detailed question view. This is what you get if you click on detailed question view, the question overview. This view contains more specific information about the selected question. So when you look on the left side, you will see the full question text from the result list. In addition, the question ID number and version will be displayed. And here the question item also has an interviewer instruction and variable information. In addition to the question you have selected, you will find on the right hand side a list of other questions belonging to the same study. So here you will find all other questions in addition to the one you have chosen that belong as you can see here to the European value study 2008. You can also enter a search term to the search within this particular list of questions. For example, I want to know what other questions with the term drop appear in this particular study. So I type in the term drop in the search field and select one of the displayed questions. And you will see the new selected question together with its details on the left hand side. And you can also display different question translations here as well. For each question, there will also be the study number and study title displayed. So here it says that this question appeared in the European value study in 2008. When you click on this link, you will also see the following information, the study description. A page with some study related information like study title, persistent ID, current version, if it's part of a study group, a link to the publisher, publication date, interview language, country, Chess topics, description, and some information on methodology. We will also provide citation information on the right hand side, information on the metadata provider and a link to the Chess data catalog, where further study related information and the data if available can be accessed. In addition, the user can access documents belonging to this study on the top right hand side where it says download documentation. So here you see all documents that are related to the study. So I decided to save and view a PDF file on weights. So you can download the documents directly as displayed here or you can select them into your basket to download them later. So I've selected the document about weights and the document about variable report into my basket to download them later. On the top right hand side, you can see the number of all selected items that you would like to download. In addition to the documents, you can also download questions and related information by clicking on the download button. If you want to compare your questions first, you can use the button compare to select the questions you want to display side by side. You select those questions by clicking on compare and as you can see, I have selected five questions to comparison and I've already saved four questions into my basket to download. So before I show you the basket, I would like to show you how you can compare your questions. The comparison view, so if you click on the icon on the right, you can see the following view. So if you're not sure which questions you would like to download, you can select them into your comparison view and see three questions at a time side by side. So the set of questions you have selected in the result list is listed here. You can also switch to other questions you have selected earlier and compare them as well. And you can also put the question into your basket to download it. The only view that is left and that I haven't showed you yet is the basket. So I selected four questions and I saved them into the basket. I can export all items now as a zip file by clicking on download basket. And that's the last view I wanted to show you regarding the user interface. Now I would like to hand over to Thomas. He's going to present the EQB architecture and requirements for metadata provider who are interested in providing us their metadata. Yes, thank you, Ezra. So yeah, let's start with a brief architecture overview of the system. So the EQB consists of the EQB front end and several back end components. At the top of this slide, you can see several archives in Europe that are the metadata providers. The service providers supply the metadata via the OAI protocol for metadata harvesting or optionally a file-based storage endpoint. The harvester component collects metadata files from the different endpoints of the service providers. The EDI flat AB is then used to handle different versions of DDI files by splitting it up into segments of the study or the question-related metadata. Currently we support several versions of DDI, such as 3.1 and 3.2 and others in the future system. The third component is the index. We use Elasticsearch to index the metadata in a unified, more uniform way so that we can handle the different DDI formats and present these metadata in a search UI and make it searchable. This search UI is programmed in Java and using the Vardim framework of the user interface technology to display and browse and filter the collected metadata. So the next slide please, Estra. So a short note on the focus of the EQB. As you can see in this slide, the question entity or the question is the content that is in the focus of the whole EQB. It stands in the center and the most important metadata that I collected from the ESP and provided to the users are the questions. And although we provide information on the response domains, the instruments or the study, the question is contained in if it is provided by the service providers. Also information on the datasets, the variables, documents, other metadata and persons and institution affiliation. But however, the focus of the EQB model is, our metadata schema starts therefore with information on the question level and also the number of provided information in the entire EQB is the highest on questions and question related information. Here you see a brief overview of the mandatory fields and some of the recommended fields. The mandatory elements that must be provided by service providers are the question represented by a text and an ID. The study title that this question belongs to, the URL and the name of the service provider and the publication year of the study. Please bear in mind that we only index fielded questions, means questions that have been run in a real study in the field, therefore the publication year is also mandatory. There are more properties, there are also recommended properties as well as technically optional but strongly recommended to enhance that metadata that can be found with the EQB. So you see on the right side some of them study persistent ID, the time method, the country, the sample procedure, the model collection or the data collection date. Of course we can provide you with the entire EQB metadata schema if you're interested. So here you see an excerpt of the metadata schema. It's an essential condition to access the display metadata accurately from all service providers. It's the standardized way and the overall structure of the EQB model. The schema includes all relevant metadata elements with the specific category of information. It represents the CESTA metadata model and the requirements for the EQB and it is compatible with the DDI life cycle metadata standard. In the schema you will find which metadata properties are mandatory, recommended or optional and also which of the elements are multilingual because EQB supports multilingual metadata. The metadata can be provided in any language, compliant with the ISO 6391 standard and we also have controlled book libraries included for example for the model collection or the sampling procedure or we also use the topic classification from CESTA. I think that's it from the architecture requirements part. All right, thank you Thomas. Now I would like to provide you a brief summary of the most important information on EQB. First of all regarding the usage of EQB. So now you heard a lot about the user interface. So if you want to browse, discover and compare survey questions and question-related information in a cross-national questioning from several CESTA service providers and beyond. If you want to access study-related information and documentation and if you want to compare questions and question-related information and export survey items then EQB might be the right tool for you. So if you are for instance a questionnaire designer and you would like to find high quality tested questions that you can use for your questionnaire or if you are a researcher and you would like to find questions on a particular topic that is relevant for your research or if you are a questionnaire translator and you would like to find translations of questions to get for example a sense of how translators handle the particular difficult translation issue for particular questions or if you are a survey methodologist and you would like to see how questions on a topic change over time and you would like to explore issues on question design then all of these reasons and more than EQB might be the right tool for you. So but if you are a service provider and you want that all of these target groups I just mentioned reuse all your metadata and data and you have the willingness and the interest in making those survey questions accessible in EQB then first of all we would like to invite you to get in touch with us so that we can provide you with more information on the requirements and can discuss how we can make your metadata available. Secondly document your metadata in DDI. We prefer DDI life cycle and we can support you with this and can provide you example XML files in DDI from other service providers so that you can see how the metadata should be documented. Third please improve your metadata documentation especially on question level so that we are able to harvest your metadata so we need you to look at the mandatory fields of EQB and last make your metadata available preferred are OAI endpoints. So now you know what the requirements are so my question to the participants here in this webinar is the social science data archive or at an institute who have question related metadata available do you want to be part of EQB then please feel free to contact us. This is our last slide before we start our question and answer session so what is next than EQB so next year we plan to launch our application because it's still work in progress. We plan to expand the coverage from our Chester service providers and metadata suppliers also outside of Chester and we will conduct user tests and we will relaunch EQB version two so that's it from our side this is all the information we would like to give you for now and I hope you got the first insight into the usage and requirements of the Chester Euro question bank so what is left is last part of the webinar the question and answer session where you have the opportunity to ask questions by typing them in into the chat box. Let me see if there are already some questions. Yes I can see questions but maybe I can start first with the questions that we received beforehand so someone from NSD asked I think we have I would like to know how the EQB can be accessed how I can promote it and how I can have researchers access it so we answered how you can use it and regarding the access of EQB this might be a question from several participants well it is still a beta version so for now we will not provide you a link yet because currently we are intensely working on the application and it can be unavailable at any time so it's still in work in progress but we will announce when we will have a stable and productive application available so if you want to get notified about our launch feel free to contact us. The second question is I'm interested in connection between Chester members databases and the EQB what are the metadata variables available the answer is as you heard we have Chester members metadata via OIE endpoints but we will also offer a five storage based solution for those who cannot provide this preferred format and the second part of the question we are a question bank so we only have a few metadata on variables like variable name label of the variable description of the variable and also variable type so if you are asking if we provide the actual data then the answer is no the actual data cannot be accessed within EQB but we will provide a link to the Chester data catalog or we already do that and the Chester service providers or other service providers study description where additional metadata on study level and the data set if they are available can be found. So now we would like to answer more questions. Hi it's Domingo from Unidata Italy is DDI 2.5 supported in some way or DDI 3? DDI 3 I cannot read the last part of the question. DDI 3 only. DDI 3 only okay well currently we have service providers who only have DICodebook so we support DDI codebook for service providers who are part of EQB for now but for next year we will ask you to provide you can provide us DDI codebook metadata but in the way we need them so as you know everyone around the world understands DDI differently have different interpretations of DDI and how the metadata is documented within DDI and this was quite a challenge or still a challenge to read all flavors of DDI interpretations and groupings so for next year there will be the possibility to use a validator tool where you can see what DDI profiles EQB has and then you can check if you meet the requirements. Do you want to add something Thomas? Should I go to the next question? Maybe we start first come first serve. I have a question from Janis Steve. It is a function to find similar question based on the one selected. So there is currently no control or no widget that does exactly that that proposes the five most similar questions to the one you have selected but as it's a search engine there is anyways a similarity measure used to rank the results by the score according to the criteria you selected. So what you could of course do is you could paste the entire question with just the relevant keywords in the search box and you would then see the questions that best match that field. And then maybe also related a little bit to the question that Adrian Dusa asked regarding the compatibility in different languages. So I think one great advantage of the EQB is that we use the test our topic classification which means that by using the filter of the topic classification regardless of the language that is used in a concrete question for example if we have one in Slovenian and one in French and the other one in Danish even if there is no concrete string matching in the question takes itself you can use the filters which are let's say language independent as the filters are in English or at least they are mapped which is the benefit of a controlled vocabulary and therefore you can filter down and drill down to the set of questions that cover the topics that you're interested in. Yeah I would say now for the first two questions or Ezra would you like to add something on that? No I have problems seeing the whole question text I don't know if you can read out the questions. I think we answered the first three questions the fourth one I see hello this is Laura Morales we will be collaborating with GASIS and EQB for the inclusion of question metadata from surveys on migrants and ethnic minorities. Minorities were interested in several aspects and from there I cannot see. So aspect one will there be enough metadata variables to describe the questions before and after whether there were any instrumentation experiments etc. So still all metadata at the level of the question and questionnaire position richer than just question text answer. So this the question carries goes on up here and answer the first part of your question. I think yes so we would definitely provide you Laura with the CMM metadata schema maybe also with a brief introduction to the DDI32 so that you can see how feature rich the metadata schema is and especially as you mentioned these tree and post question text. So this is something which is definitely there and you can also limit your search to those texts. So I would give a cautious yes to this question as an answer and to go more into detail I think it's good that we have a look at the system data model maybe together or we just provide it to you and maybe it's clear already then if not we can of course get in touch. Then the second part of your question how will you work around the likely multiplication of questions that are identical but have been asked multiple surveys across several countries and service providers. For example if all this says the archives have the questions relating to this European Social Survey for each of these the same questions will be multiplied by the other nation I think it's N by N by factor N. How will this be worked out so that identical questions are only listed once and then which provides the list of all the surveys in which it was thinking. Okay Ezra do you have to have an answer to that question? Excuse me? Do you have an answer to that question so how do we address the issue that we are currently lifting fielded questions and there's of course the it's very likely and obvious that very soon we will have questions that are similar if not identical in wording but they have been fielded in two or more different situations. So Laura's questions how are we able to identify all those identical questions? That's a good question but for sure we will display all questions even if they are appeared in different studies or appeared in the same study and are provided by several service providers. So every question has its own ID if I understand the question right so you want to know how the questions will be identified. So there are question IDs to identify them. So I'm not sure whether it's the question IDs or really the questions that stem from the same instrument. I think that's what the question is targeting at correct me if I'm wrong. Yeah but maybe we can get back to you Laura and we'll provide you a more detailed answer to this. So maybe that's a good solution to provide you an answer afterwards. Is there any more parts of the questions that I missed or should we go to the next one? Next question was from Bodil Agasosta. What time methods are there in the question? Yeah the time methods is a controlled vocabulary from the DDI so from the DDI Alliance. This is the controlled vocabulary from the DDI. Next one. I think these are the replies from Laura to our answer of. Oh okay. Yeah. Okay. Okay thanks. Are there any more questions that I cannot see? I don't know why this view shows only one line but I hope we didn't miss a question. No I have the question we don't maximize and that's all the questions that we have so far. Maybe yeah well we definitely want to invite you to participate in your question bank. Particularly if you are a potential service provider and you have interest in increasing the visibility of your fielded questionnaires. I think that EQB provides an excellent opportunity to increase the scope and the visibility of your questionnaires. Yes and if you have any more questions that come to you later feel free to contact us as well. So I think we came to the end of our webinar. So thank you all for joining and thank you for your interest. It was a pleasure to us introducing our project. So if you have any questions remaining as I said feel free to contact us and let us know if your institution is interested in joining EQB. So goodbye and thank you. Thank you.

 Okay, hello everyone and welcome to today's webinar, the Chester Eurea Question Bank,  Search, Find and Reuse Questionnaire Items from Social Scientific Research.

In addition, the user can access documents belonging to this study on the top right hand  side where it says download documentation.  So here you see all documents that are related to the study.  So I decided to save and view a PDF file on weights.  So you can download the documents directly as displayed here or you can select them into  your basket to download them later.  So I've selected the document about weights and the document about variable report into  my basket to download them later.

Please bear in mind that we only index fielded questions, means questions that have been  run in a real study in the field, therefore the publication year is also mandatory.  There are more properties, there are also recommended properties as well as technically  optional but strongly recommended to enhance that metadata that can be found with the  EQB.  So you see on the right side some of them study persistent ID, the time method, the country,  the sample procedure, the model collection or the data collection date.  Of course we can provide you with the entire EQB metadata schema if you're interested.  So here you see an excerpt of the metadata schema.  It's an essential condition to access the display metadata accurately from all service  providers.  It's the standardized way and the overall structure of the EQB model.  The schema includes all relevant metadata elements with the specific category of information.  It represents the CESTA metadata model and the requirements for the EQB and it is compatible  with the DDI life cycle metadata standard.  In the schema you will find which metadata properties are mandatory, recommended or optional  and also which of the elements are multilingual because EQB supports multilingual metadata.  The metadata can be provided in any language, compliant with the ISO 6391 standard and we  also have controlled book libraries included for example for the model collection or the  sampling procedure or we also use the topic classification from CESTA.  I think that's it from the architecture requirements part.  All right, thank you Thomas.  Now I would like to provide you a brief summary of the most important information on EQB.  First of all regarding the usage of EQB.  So now you heard a lot about the user interface.  So if you want to browse, discover and compare survey questions and question-related information  in a cross-national questioning from several CESTA service providers and beyond.  If you want to access study-related information and documentation and if you want to compare  questions and question-related information and export survey items then EQB might be  the right tool for you.  So if you are for instance a questionnaire designer and you would like to find high quality  tested questions that you can use for your questionnaire or if you are a researcher and  you would like to find questions on a particular topic that is relevant for your research or  if you are a questionnaire translator and you would like to find translations of questions  to get for example a sense of how translators handle the particular difficult translation  issue for particular questions or if you are a survey methodologist and you would like  to see how questions on a topic change over time and you would like to explore issues  on question design then all of these reasons and more than EQB might be the right tool  for you.  So but if you are a service provider and you want that all of these target groups I just  mentioned reuse all your metadata and data and you have the willingness and the interest  in making those survey questions accessible in EQB then first of all we would like to  invite you to get in touch with us so that we can provide you with more information on  the requirements and can discuss how we can make your metadata available.  Secondly document your metadata in DDI.  We prefer DDI life cycle and we can support you with this and can provide you example  XML files in DDI from other service providers so that you can see how the metadata should  be documented.  Third please improve your metadata documentation especially on question level so that we are  able to harvest your metadata so we need you to look at the mandatory fields of EQB  and last make your metadata available preferred are OAI endpoints.  So now you know what the requirements are so my question to the participants here in  this webinar is the social science data archive or at an institute who have question related  metadata available do you want to be part of EQB then please feel free to contact us.  This is our last slide before we start our question and answer session so what is next  than EQB so next year we plan to launch our application because it's still work in progress.  We plan to expand the coverage from our Chester service providers and metadata suppliers also  outside of Chester and we will conduct user tests and we will relaunch EQB version two  so that's it from our side this is all the information we would like to give you for  now and I hope you got the first insight into the usage and requirements of the Chester  Euro question bank so what is left is last part of the webinar the question and answer  session where you have the opportunity to ask questions by typing them in into the chat  box.  Let me see if there are already some questions.  Yes I can see questions but maybe I can start first with the questions that we received  beforehand so someone from NSD asked I think we have I would like to know how the EQB can  be accessed how I can promote it and how I can have researchers access it so we answered  how you can use it and regarding the access of EQB this might be a question from several  participants well it is still a beta version so for now we will not provide you a link  yet because currently we are intensely working on the application and it can be unavailable  at any time so it's still in work in progress but we will announce when we will have a stable  and productive application available so if you want to get notified about our launch  feel free to contact us.  The second question is I'm interested in connection between Chester members databases  and the EQB what are the metadata variables available the answer is as you heard we have  Chester members metadata via OIE endpoints but we will also offer a five storage based  solution for those who cannot provide this preferred format and the second part of the  question we are a question bank so we only have a few metadata on variables like variable  name label of the variable description of the variable and also variable type so if  you are asking if we provide the actual data then the answer is no the actual data cannot  be accessed within EQB but we will provide a link to the Chester data catalog or we already  do that and the Chester service providers or other service providers study description  where additional metadata on study level and the data set if they are available can be  found.  So now we would like to answer more questions.  Hi it's Domingo from Unidata Italy is DDI 2.5 supported in some way or DDI 3?  DDI 3 I cannot read the last part of the question.  DDI 3 only.  DDI 3 only okay well currently we have service providers who only have DICodebook so we support  DDI codebook for service providers who are part of EQB for now but for next year we will  ask you to provide you can provide us DDI codebook metadata but in the way we need them  so as you know everyone around the world understands DDI differently have different interpretations  of DDI and how the metadata is documented within DDI and this was quite a challenge  or still a challenge to read all flavors of DDI interpretations and groupings so for  next year there will be the possibility to use a validator tool where you can see what  DDI profiles EQB has and then you can check if you meet the requirements.  Do you want to add something Thomas?  Should I go to the next question?  Maybe we start first come first serve.  I have a question from Janis Steve.  It is a function to find similar question based on the one selected.  So there is currently no control or no widget that does exactly that that proposes the five  most similar questions to the one you have selected but as it's a search engine there  is anyways a similarity measure used to rank the results by the score according to the  criteria you selected.  So what you could of course do is you could paste the entire question with just the relevant  keywords in the search box and you would then see the questions that best match that field.  And then maybe also related a little bit to the question that Adrian Dusa asked regarding  the compatibility in different languages.  So I think one great advantage of the EQB is that we use the test our topic classification  which means that by using the filter of the topic classification regardless of the language  that is used in a concrete question for example if we have one in Slovenian and one in French  and the other one in Danish even if there is no concrete string matching in the question  takes itself you can use the filters which are let's say language independent as the  filters are in English or at least they are mapped which is the benefit of a controlled  vocabulary and therefore you can filter down and drill down to the set of questions that  cover the topics that you're interested in.  Yeah I would say now for the first two questions or Ezra would you like to add something on  that?  No I have problems seeing the whole question text I don't know if you can read out the  questions.  I think we answered the first three questions the fourth one I see hello this is Laura Morales  we will be collaborating with GASIS and EQB for the inclusion of question metadata from  surveys on migrants and ethnic minorities.  Minorities were interested in several aspects and from there I cannot see.  So aspect one will there be enough metadata variables to describe the questions before  and after whether there were any instrumentation experiments etc.  So still all metadata at the level of the question and questionnaire position richer  than just question text answer.  So this the question carries goes on up here and answer the first part of your question.  I think yes so we would definitely provide you Laura with the CMM metadata schema maybe  also with a brief introduction to the DDI32 so that you can see how feature rich the  metadata schema is and especially as you mentioned these tree and post question text.  So this is something which is definitely there and you can also limit your search to those  texts.  So I would give a cautious yes to this question as an answer and to go more into detail I  think it's good that we have a look at the system data model maybe together or we just  provide it to you and maybe it's clear already then if not we can of course get in touch.  Then the second part of your question how will you work around the likely multiplication  of questions that are identical but have been asked multiple surveys across several countries  and service providers.  For example if all this says the archives have the questions relating to this European  Social Survey for each of these the same questions will be multiplied by the other nation I think  it's N by N by factor N.  How will this be worked out so that identical questions are only listed once and then which  provides the list of all the surveys in which it was thinking.  Okay Ezra do you have to have an answer to that question?  Excuse me?  Do you have an answer to that question so how do we address the issue that we are currently  lifting fielded questions and there's of course the it's very likely and obvious that very  soon we will have questions that are similar if not identical in wording but they have  been fielded in two or more different situations.  So Laura's questions how are we able to identify all those identical questions?  That's a good question but for sure we will display all questions even if they are appeared  in different studies or appeared in the same study and are provided by several service  providers.  So every question has its own ID if I understand the question right so you want to know how  the questions will be identified.  So there are question IDs to identify them.  So I'm not sure whether it's the question IDs or really the questions that stem from  the same instrument.  I think that's what the question is targeting at correct me if I'm wrong.  Yeah but maybe we can get back to you Laura and we'll provide you a more detailed answer  to this.  So maybe that's a good solution to provide you an answer afterwards.  Is there any more parts of the questions that I missed or should we go to the next one?  Next question was from Bodil Agasosta.  What time methods are there in the question?  Yeah the time methods is a controlled vocabulary from the DDI so from the DDI Alliance.  This is the controlled vocabulary from the DDI.  Next one.  I think these are the replies from Laura to our answer of.  Oh okay.  Yeah.  Okay.  Okay thanks.  Are there any more questions that I cannot see?  I don't know why this view shows only one line but I hope we didn't miss a question.  No I have the question we don't maximize and that's all the questions that we have so far.  Maybe yeah well we definitely want to invite you to participate in your question bank.  Particularly if you are a potential service provider and you have interest in increasing  the visibility of your fielded questionnaires.  I think that EQB provides an excellent opportunity to increase the scope and the visibility of  your questionnaires.  Yes and if you have any more questions that come to you later feel free to contact us as  well.  So I think we came to the end of our webinar.  So thank you all for joining and thank you for your interest.  It was a pleasure to us introducing our project.  So if you have any questions remaining as I said feel free to contact us and let us know  if your institution is interested in joining EQB.  So goodbye and thank you.  Thank you.

Okay, hello everyone and welcome to today's webinar, the Chester Eurea Question Bank, Search, Find and Reuse Questionnaire Items from Social Scientific Research. First of all, we would like to introduce ourselves. My name is Esra Akdenes and I work at the Data Archive at GESIS, Leibniz Institute for the Social Sciences in Germany. And I'm the project manager of the Chester Eurea Question Bank project and I'm mainly responsible for the metadata, the content and the communication with our service providers. Hello, my name is Thomas Kremmer, I'm a colleague from Esra at GESIS in Cologne and I joined the EQB project in September and my responsibilities within others are the user interface and partly the indexing of the metadata. Thank you. Before we start, I would like you to know that you are currently all muted but you can post questions to the chat box at any time and we'll be answering questions at the end of the session and if we don't get to your question during today's webinar, we will follow up with you afterwards. And today's webinar will be available after the live session. If you're interested in providing it to your colleagues, you will be notified via email when and where the slides and the recording are available. So let's get started. This webinar is divided into five parts. In the first part, we will give a brief overview of the Chester EQB project and we'll introduce the idea behind the Europeanwide Question Bank. In the second part, the current user interface will be presented. We will demonstrate how the European Question Bank helps users find, compare and download questions as well as question-related and study-related information. In the third part of the webinar, we will present the EQB architecture and the purpose of the components and we will also introduce the requirements for metadata providers and developers who are interested in supplying their metadata to EQB. In the fourth section, we will briefly summarize everything you need to know and we will end our webinar with answering your questions. So first of all, I would like to introduce the project. The Chester Eurequestion Bank project started in 2016 and is funded by Chester. Chester stands for Consortium of European Social Science Data Archives. It is an alliance of social science data archives of currently 20 member countries and in the EQB project, we are currently 10 Chester Service Providers working on EQB and GASIS has the lead of the project and we are responsible for the project management and for the technical development of EQB. So Chester creates and runs services for the social sciences and one of them is the Eur question bank, which is currently under development. So why is it necessary to develop a European-wide question bank and what are the benefits of it? As some of you might know, existing question data banks for social sciences mainly operate on the national level, meaning that they only include questions from surveys that have been conducted within their own countries. The disadvantage of this is that this limits the pool of available questions for users. The Eur question bank will be a solution that has been envisioned for many years. But was never implemented so far. It will link existing question data banks and will offer a single point of entry for survey questions from many service providers. So EQB will be a cross-national question bank with a central search facility across many Chester survey holdings and hopefully beyond. So users will have access to many questions, question-related information and study information within one application from several European countries. So now I will introduce this application and will show how users can use this application to search, compare and download questions. Here you see the first page of the current prototype. So EQB is a search engine that will enable users to search survey questions together with a study-related information and documentation. So let's start with the search. This is a result page which you get when you type in a term into the search box. Following use case, I'm a researcher and I would like to design a questionnaire on the topic employment. And I'm not sure how I should formulate my questions. But I know that the term job should appear in the question text. So I click, so I type in job and start the search. Before I look into my results, I can narrow my search term by question text, response categories, study titles and pre and post question text. So here the system browsers the term job in all available question text and all questions containing the term job and the metadata will be displayed. In addition, the search can be supported by filters, meaning the search can be narrowed down by serials, collection year, country, language and mode of collection. So the filters will help you to search more precisely and to refine your search query. For example, you search for the term job and tick question texts and select the country filter for Sweden. This will display questions containing the word job in the question text for data collected in Sweden. Before setting filters, you will see all available questions and some additional information for each question. A detailed question view, the response categories, the study in which the question appeared and a drop down to select different language versions. So the user can switch between different language translations of a question by selecting a language. The user can also view the response categories of the question and the user can see more question related information by clicking on detailed question view. This is what you get if you click on detailed question view, the question overview. This view contains more specific information about the selected question. So when you look on the left side, you will see the full question text from the result list. In addition, the question ID number and version will be displayed. And here the question item also has an interviewer instruction and variable information. In addition to the question you have selected, you will find on the right hand side a list of other questions belonging to the same study. So here you will find all other questions in addition to the one you have chosen that belong as you can see here to the European value study 2008. You can also enter a search term to the search within this particular list of questions. For example, I want to know what other questions with the term drop appear in this particular study. So I type in the term drop in the search field and select one of the displayed questions. And you will see the new selected question together with its details on the left hand side. And you can also display different question translations here as well. For each question, there will also be the study number and study title displayed. So here it says that this question appeared in the European value study in 2008. When you click on this link, you will also see the following information, the study description. A page with some study related information like study title, persistent ID, current version, if it's part of a study group, a link to the publisher, publication date, interview language, country, Chess topics, description, and some information on methodology. We will also provide citation information on the right hand side, information on the metadata provider and a link to the Chess data catalog, where further study related information and the data if available can be accessed. In addition, the user can access documents belonging to this study on the top right hand side where it says download documentation. So here you see all documents that are related to the study. So I decided to save and view a PDF file on weights. So you can download the documents directly as displayed here or you can select them into your basket to download them later. So I've selected the document about weights and the document about variable report into my basket to download them later. On the top right hand side, you can see the number of all selected items that you would like to download. In addition to the documents, you can also download questions and related information by clicking on the download button. If you want to compare your questions first, you can use the button compare to select the questions you want to display side by side. You select those questions by clicking on compare and as you can see, I have selected five questions to comparison and I've already saved four questions into my basket to download. So before I show you the basket, I would like to show you how you can compare your questions. The comparison view, so if you click on the icon on the right, you can see the following view. So if you're not sure which questions you would like to download, you can select them into your comparison view and see three questions at a time side by side. So the set of questions you have selected in the result list is listed here. You can also switch to other questions you have selected earlier and compare them as well. And you can also put the question into your basket to download it. The only view that is left and that I haven't showed you yet is the basket. So I selected four questions and I saved them into the basket. I can export all items now as a zip file by clicking on download basket. And that's the last view I wanted to show you regarding the user interface. Now I would like to hand over to Thomas. He's going to present the EQB architecture and requirements for metadata provider who are interested in providing us their metadata. Yes, thank you, Ezra. So yeah, let's start with a brief architecture overview of the system. So the EQB consists of the EQB front end and several back end components. At the top of this slide, you can see several archives in Europe that are the metadata providers. The service providers supply the metadata via the OAI protocol for metadata harvesting or optionally a file-based storage endpoint. The harvester component collects metadata files from the different endpoints of the service providers. The EDI flat AB is then used to handle different versions of DDI files by splitting it up into segments of the study or the question-related metadata. Currently we support several versions of DDI, such as 3.1 and 3.2 and others in the future system. The third component is the index. We use Elasticsearch to index the metadata in a unified, more uniform way so that we can handle the different DDI formats and present these metadata in a search UI and make it searchable. This search UI is programmed in Java and using the Vardim framework of the user interface technology to display and browse and filter the collected metadata. So the next slide please, Estra. So a short note on the focus of the EQB. As you can see in this slide, the question entity or the question is the content that is in the focus of the whole EQB. It stands in the center and the most important metadata that I collected from the ESP and provided to the users are the questions. And although we provide information on the response domains, the instruments or the study, the question is contained in if it is provided by the service providers. Also information on the datasets, the variables, documents, other metadata and persons and institution affiliation. But however, the focus of the EQB model is, our metadata schema starts therefore with information on the question level and also the number of provided information in the entire EQB is the highest on questions and question related information. Here you see a brief overview of the mandatory fields and some of the recommended fields. The mandatory elements that must be provided by service providers are the question represented by a text and an ID. The study title that this question belongs to, the URL and the name of the service provider and the publication year of the study. Please bear in mind that we only index fielded questions, means questions that have been run in a real study in the field, therefore the publication year is also mandatory. There are more properties, there are also recommended properties as well as technically optional but strongly recommended to enhance that metadata that can be found with the EQB. So you see on the right side some of them study persistent ID, the time method, the country, the sample procedure, the model collection or the data collection date. Of course we can provide you with the entire EQB metadata schema if you're interested. So here you see an excerpt of the metadata schema. It's an essential condition to access the display metadata accurately from all service providers. It's the standardized way and the overall structure of the EQB model. The schema includes all relevant metadata elements with the specific category of information. It represents the CESTA metadata model and the requirements for the EQB and it is compatible with the DDI life cycle metadata standard. In the schema you will find which metadata properties are mandatory, recommended or optional and also which of the elements are multilingual because EQB supports multilingual metadata. The metadata can be provided in any language, compliant with the ISO 6391 standard and we also have controlled book libraries included for example for the model collection or the sampling procedure or we also use the topic classification from CESTA. I think that's it from the architecture requirements part. All right, thank you Thomas. Now I would like to provide you a brief summary of the most important information on EQB. First of all regarding the usage of EQB. So now you heard a lot about the user interface. So if you want to browse, discover and compare survey questions and question-related information in a cross-national questioning from several CESTA service providers and beyond. If you want to access study-related information and documentation and if you want to compare questions and question-related information and export survey items then EQB might be the right tool for you. So if you are for instance a questionnaire designer and you would like to find high quality tested questions that you can use for your questionnaire or if you are a researcher and you would like to find questions on a particular topic that is relevant for your research or if you are a questionnaire translator and you would like to find translations of questions to get for example a sense of how translators handle the particular difficult translation issue for particular questions or if you are a survey methodologist and you would like to see how questions on a topic change over time and you would like to explore issues on question design then all of these reasons and more than EQB might be the right tool for you. So but if you are a service provider and you want that all of these target groups I just mentioned reuse all your metadata and data and you have the willingness and the interest in making those survey questions accessible in EQB then first of all we would like to invite you to get in touch with us so that we can provide you with more information on the requirements and can discuss how we can make your metadata available. Secondly document your metadata in DDI. We prefer DDI life cycle and we can support you with this and can provide you example XML files in DDI from other service providers so that you can see how the metadata should be documented. Third please improve your metadata documentation especially on question level so that we are able to harvest your metadata so we need you to look at the mandatory fields of EQB and last make your metadata available preferred are OAI endpoints. So now you know what the requirements are so my question to the participants here in this webinar is the social science data archive or at an institute who have question related metadata available do you want to be part of EQB then please feel free to contact us. This is our last slide before we start our question and answer session so what is next than EQB so next year we plan to launch our application because it's still work in progress. We plan to expand the coverage from our Chester service providers and metadata suppliers also outside of Chester and we will conduct user tests and we will relaunch EQB version two so that's it from our side this is all the information we would like to give you for now and I hope you got the first insight into the usage and requirements of the Chester Euro question bank so what is left is last part of the webinar the question and answer session where you have the opportunity to ask questions by typing them in into the chat box. Let me see if there are already some questions. Yes I can see questions but maybe I can start first with the questions that we received beforehand so someone from NSD asked I think we have I would like to know how the EQB can be accessed how I can promote it and how I can have researchers access it so we answered how you can use it and regarding the access of EQB this might be a question from several participants well it is still a beta version so for now we will not provide you a link yet because currently we are intensely working on the application and it can be unavailable at any time so it's still in work in progress but we will announce when we will have a stable and productive application available so if you want to get notified about our launch feel free to contact us. The second question is I'm interested in connection between Chester members databases and the EQB what are the metadata variables available the answer is as you heard we have Chester members metadata via OIE endpoints but we will also offer a five storage based solution for those who cannot provide this preferred format and the second part of the question we are a question bank so we only have a few metadata on variables like variable name label of the variable description of the variable and also variable type so if you are asking if we provide the actual data then the answer is no the actual data cannot be accessed within EQB but we will provide a link to the Chester data catalog or we already do that and the Chester service providers or other service providers study description where additional metadata on study level and the data set if they are available can be found. So now we would like to answer more questions. Hi it's Domingo from Unidata Italy is DDI 2.5 supported in some way or DDI 3? DDI 3 I cannot read the last part of the question. DDI 3 only. DDI 3 only okay well currently we have service providers who only have DICodebook so we support DDI codebook for service providers who are part of EQB for now but for next year we will ask you to provide you can provide us DDI codebook metadata but in the way we need them so as you know everyone around the world understands DDI differently have different interpretations of DDI and how the metadata is documented within DDI and this was quite a challenge or still a challenge to read all flavors of DDI interpretations and groupings so for next year there will be the possibility to use a validator tool where you can see what DDI profiles EQB has and then you can check if you meet the requirements. Do you want to add something Thomas? Should I go to the next question? Maybe we start first come first serve. I have a question from Janis Steve. It is a function to find similar question based on the one selected. So there is currently no control or no widget that does exactly that that proposes the five most similar questions to the one you have selected but as it's a search engine there is anyways a similarity measure used to rank the results by the score according to the criteria you selected. So what you could of course do is you could paste the entire question with just the relevant keywords in the search box and you would then see the questions that best match that field. And then maybe also related a little bit to the question that Adrian Dusa asked regarding the compatibility in different languages. So I think one great advantage of the EQB is that we use the test our topic classification which means that by using the filter of the topic classification regardless of the language that is used in a concrete question for example if we have one in Slovenian and one in French and the other one in Danish even if there is no concrete string matching in the question takes itself you can use the filters which are let's say language independent as the filters are in English or at least they are mapped which is the benefit of a controlled vocabulary and therefore you can filter down and drill down to the set of questions that cover the topics that you're interested in. Yeah I would say now for the first two questions or Ezra would you like to add something on that? No I have problems seeing the whole question text I don't know if you can read out the questions. I think we answered the first three questions the fourth one I see hello this is Laura Morales we will be collaborating with GASIS and EQB for the inclusion of question metadata from surveys on migrants and ethnic minorities. Minorities were interested in several aspects and from there I cannot see. So aspect one will there be enough metadata variables to describe the questions before and after whether there were any instrumentation experiments etc. So still all metadata at the level of the question and questionnaire position richer than just question text answer. So this the question carries goes on up here and answer the first part of your question. I think yes so we would definitely provide you Laura with the CMM metadata schema maybe also with a brief introduction to the DDI32 so that you can see how feature rich the metadata schema is and especially as you mentioned these tree and post question text. So this is something which is definitely there and you can also limit your search to those texts. So I would give a cautious yes to this question as an answer and to go more into detail I think it's good that we have a look at the system data model maybe together or we just provide it to you and maybe it's clear already then if not we can of course get in touch. Then the second part of your question how will you work around the likely multiplication of questions that are identical but have been asked multiple surveys across several countries and service providers. For example if all this says the archives have the questions relating to this European Social Survey for each of these the same questions will be multiplied by the other nation I think it's N by N by factor N. How will this be worked out so that identical questions are only listed once and then which provides the list of all the surveys in which it was thinking. Okay Ezra do you have to have an answer to that question? Excuse me? Do you have an answer to that question so how do we address the issue that we are currently lifting fielded questions and there's of course the it's very likely and obvious that very soon we will have questions that are similar if not identical in wording but they have been fielded in two or more different situations. So Laura's questions how are we able to identify all those identical questions? That's a good question but for sure we will display all questions even if they are appeared in different studies or appeared in the same study and are provided by several service providers. So every question has its own ID if I understand the question right so you want to know how the questions will be identified. So there are question IDs to identify them. So I'm not sure whether it's the question IDs or really the questions that stem from the same instrument. I think that's what the question is targeting at correct me if I'm wrong. Yeah but maybe we can get back to you Laura and we'll provide you a more detailed answer to this. So maybe that's a good solution to provide you an answer afterwards. Is there any more parts of the questions that I missed or should we go to the next one? Next question was from Bodil Agasosta. What time methods are there in the question? Yeah the time methods is a controlled vocabulary from the DDI so from the DDI Alliance. This is the controlled vocabulary from the DDI. Next one. I think these are the replies from Laura to our answer of. Oh okay. Yeah. Okay. Okay thanks. Are there any more questions that I cannot see? I don't know why this view shows only one line but I hope we didn't miss a question. No I have the question we don't maximize and that's all the questions that we have so far. Maybe yeah well we definitely want to invite you to participate in your question bank. Particularly if you are a potential service provider and you have interest in increasing the visibility of your fielded questionnaires. I think that EQB provides an excellent opportunity to increase the scope and the visibility of your questionnaires. Yes and if you have any more questions that come to you later feel free to contact us as well. So I think we came to the end of our webinar. So thank you all for joining and thank you for your interest. It was a pleasure to us introducing our project. So if you have any questions remaining as I said feel free to contact us and let us know if your institution is interested in joining EQB. So goodbye and thank you. Thank you.

will give a brief overview of the Chester EQB the current user interface will be presented. We will demonstrate how the European Question Bank helps users find, compare and download questions as well as question-related and study-related information. In the third part of the webinar, we will present the EQB architecture and the purpose of the components and we will also introduce the requirements for metadata providers and metadata to EQB. In the fourth section, we will introduce the project. The Chester Eurequestion suppliers also outside of Chester and we will
