An Exemplary Survey Implementation on Text Mining with Rapid Miner
Recently many disciplines such as databases, statistics, and information retrieval have affected the growth of data mining. By this phenomenon, data mining had been allowing to extract information or knowledge from these data. Data mining employs diverse techniques based on this phenomenon, but most existing approach is data analysis and text mining. Text Mining allows various analyses for data representing the new framework known as Information Extraction. The extraction of information from unstructured resources has released new paths for analyzing, organizing and querying data. Adapting and implementing these patterns has been time consuming in the past but with the use of some discovery tools now this task has been significantly easier. The first part of the study includes the mining of an unstructured text and the second part is visualization, both provided by Rapid Miner. The visualization part has some subparts which are directly related to the conducted survey dedicated to particular individuals. These subparts are; finding correlation between the attributes of people, determination of the most weighted attribute and clustering subpart which classifies a group of people that has more similarity between them. Each of these parts has been examined and shown by definitions, examples, analysis and conclusions.

Sentiment Analysis of English Tweets Using Rapid Miner
Social networking sites these days are great source of communication for internet users. So these are important source for understanding the emotions of people. In this paper, we use data mining techniques for the purpose of classification to perform sentiment analysis on the views people have shared in Twitter. We collect dataset, i.e. The tweets from twitter that are in natual language and apply text mining techniques tokenization, stemming etc to convert them into useful form and then use it for building sentiment classifier that is able to predict happy, sad and neutral sentiments for a particular tweet. Rapid Miner tool is being used, that helps in building the classifier as well as able to apply it to the testing dataset. We are using two different classifiers and also compare their results in order to find which one gives better results.

Comparison of Classification Algorithms in Text Mining
Web Mining is searching useful data from the World Wide Web repository which is divided into Content Mining, Usage Mining and Structure Mining in which Content Mining uses text, images, Audio and Video to extract useful information which is Unstructured. Web Mining is sub process of Data Mining which involves Anomaly detection, Classification, Clustering, Association Rule Mining, Regression and Summarization. This discovers patterns in large data sets involving many disciplines such as Artificial Intelligence, Machine Learning, Statistics and Database Systems. Machine Learning is the emerging technology to make the machines to predict values for new data inputs according to the previous data inputs trained with some Algorithms. Among all, the Classification is in supervised Learning of Machine learning where a training set of correctly predicted observation is available. In this paper three algorithms Naive Bayes, Random Forest and Support Vector Machine used in Rapid Miner with 500 example dataset. Accuracy and Classification error of three algorithms compared and a chart is displayed which shows that Support vector machine is 97.40% accurate than other two algorithms.

Arabic dialects classification using text mining techniques
Arabic language is one of the important languages in the world. It is spoken in many countries. However, every region in the Arabic world has its own dialect. The spoken dialects start to be written recently with the rise of usage of social media tools such as Facebook and Twitter. In this paper, we discuss the development of a classifiers for six main Arabic dialects that are Gulf, Iraqi, Shami, Moroccan and Sudanese dialect, and Egyptian dialects. We used 2000 tweets that belonged to one of the six Arabic dialects to be used as data to our classifiers. The classifier was implemented using rapid miner tool. We used decision tree, naive Bayes and rule based (Ripper) classification algorithms for classification purpose. The classifiers from three algorithms were able to classify the tweets into one of six dialects with some error rate but the classifier study revealed that algorithms were able to pick the keywords that are the salient features of the different dialects.
