Challenges in Cross-Cultural/Multilingual Music Information Seeking
Understanding and meeting the needs of a broad range of music users across different cultures and languages are central in designing a global music digital library. This exploratory study examines cross-cultural/multilingual music information seeking behaviors and reveals some important characteristics of these behaviors by analyzing 107 authentic music information queries from a Korean knowledge search portal Naver 지식 (knowledge) iN and 150 queries from Google Answers website. We conclude that new sets of access points must be developed to accommodate music queries that cross cultural or language boundaries.

Survey Of Music Information Needs, Uses, And Seeking Behaviours: Preliminary Findings
User studies focusing upon real-life music information needs, uses and seeking behaviours are still very scarce in the music information retrieval (MIR) and music digital library (MDL) fields. We are conducting a multigroup survey in an attempt to acquire information that can help eradicate false assumptions in designing MIR systems. Our goal is to provide an empirical basis for MIR/MDL system development. In this paper, we present our preliminary findings and analyses based on the 427 user responses we have received to date. Two major themes have been uncovered thus far that could have a significant influence the future development of successful MIR/MDL systems. First, people display “public information-seeking” behaviours by making use of collective knowledge and/or opinions of others about music such as reviews, ratings, recommendations, etc. in their music information-seeking. Second, respondents expressed needs for contextual metadata in addition to traditional bibliographic metadata.

VTAssist: a location-based feedback notification system for the disabled
The needs of individuals with limited mobility have not been given as much importance as those of other users of internet-accessible mobile devices. Disabled users have information and service needs that are unique and a timely delivery of these services and information can be invaluable. This has motivated us toward the development of VTAssist, an application that attempts to provide critical location-based information about building accessibility to impaired users. This paper discusses our initial implementation of VTAssist and reports on preliminary evaluation results. Our results indicate that our system can help wheelchair users to better understand and navigate around environments.

The formal definition of the BASIC language
The translator The translator which transforms the parsed text into the abstract text (that is, a text which conforms to the abstract syntax and takes into account the default conditions) is peculiar to the language in the Lucas system but has not been developed here since it is the author's opinion that a general translator may be developed which is applicable to all languages. The default rules for Basic are:

A Practitioner's Approach to Normalizing XQuery Expressions
XQuery becomes a standard of the XML query language. Just like in SQL, XQuery allows nested expressions. To optimize XQuery processing, a lot of research has been done on normalization, i.e., transforming nested expressions to equivalent unnested ones. Previous normalization rules are classified into two categories – source-level and algebra-level – depending on whether a construct is specified by using a query language or an algebraic expression. In implementation point of view, we contend that the source-level rule is preferable to the algebra-level rule because algebras used for normalization are hard to be directly exploited in a typical DBMS. However, a complete set of source-level rules is yet to be developed. In this paper, we propose source-level rules for normalizing XQuery expressions and present an implementation mechanism. We show that our rules are correct and complete according to the nesting types classified by Kim. Our mechanism is easily implementable since it adapts the well-known Query Graph Model (QGM) representation. We have successfully implemented this mechanism into our XML DBMS named Odysseus/XML.

Image is everything: advancing HCI knowledge and interface design using the system image
As the field of human-computer interaction matures, the need for proven, dependable engineering processes for interface development becomes apparent. Our continuing work in developing LINK-UP, an integrated design and reuse environment, suggests that a better understanding of the system image is key to the successful evaluation of design prototypes, and an aide in applying knowledge from the repository. This paper describes our ongoing work to enhance LINK-UP by developing and augmenting the system image to make it the central communication point between different stages of design and between different stakeholders. We report on a study of the new task flow that demonstrated the value of the system image within a broader design context. Overall, our findings indicate that the effective creation and use of knowledge repositories by novice HCI designers hinges on successful application of existing HCI design concepts within a practical integrated design environment.
