Abstract

Information Science, which attained the status of a discipline in the 1980s, has been enriched by Inputs from a number of disciplines ranging from computer technology to psychology. A predominant characteristic of research in Information Retrieval in recent years has been the adoption of a 'user-centered' approach to the design of information systems. This shift in the emphasis began primarily after Belkin enunciated his ASK (Anomalous State of Knowledge) hypothesis. Research in the Cognitive Sciences has the potential to contribute substantially to enhancing all Information Retrieval processes. This paper emphasizes the importance of adopting a broad-based approach to cognitive research in IR and suggests that there is a need for exploring the relevance of analytico-synthetic approach and related research in the design of IR systems.

Abstract

Gives operational definitions of work, associated work, composite work and other selected terms. Mentions the challenges posed by the abundant availability of digital resources in different media, forms and formats to catalogers in particular and information professionals in general. Discusses with examples the applicability and adequacy of the rules and prescriptions of ISBD(ER) and AACR2, 1998 rev. for cataloging multimedia resources on CD, in view of the fact that the record medium, the physical form and format affect the effectiveness of accessing, retrieval and use of a work.

Abstract

The scholarly community is increasingly employing the Web both for publication of scholarly output and for locating and accessing relevant scholarly literature. Organization of this vast body of digital information assumes significance in this context. The sheer volume of digital information to be handled makes traditional indexing and knowledge representation strategies ineffective and impractical. It is, therefore, worth exploring new approaches. An approach being discussed considers the intrinsic semantics of texts of documents. Based on the hypothesis that noun phrases in a text are semantically rich in terms of their ability to represent the subject content of the document, this approach seeks to identify and extract noun phrases instead of single keywords, and use them as descriptors. This paper presents a methodology that has been developed for extracting noun phrases from Portuguese texts. The results of an experiment carried out to test the adequacy of the methodology are also presented.

Based on experiences with the design and development of a Tamil-English bilingual thesaurus this paper discusses with examples: (1) some issues related to vocabulary management in multilingual thesauri in culture-specific domains; (2) special aspects of the Tamil language in this regard; (3) alternative ways of linking certain descriptors to lengthy lists of NTs and RTs; (4) advantages of integrated use of two or more knowledge organization tools; and (5) use of the bilingual thesaurus for certain types of research in Tamil. Issues related to equivalence, non-hierarchic associative relationships, homographs, NTs are discussed. The paper suggests that integrated use of two or more knowledge organization tools adds value.

Abstract

This paper briefly traces the history of library education in India and examines the status of bibliographic organization and control in the country as a major factor influencing the nature and content of courses in knowledge organization. The two basic documents from the University Grants Commission - the first one issued in 1965 and the recent one in 2001 - that have influenced university level course contents have been examined. Finally, the nature of changes that are being brought about in recent years in some universities has been highlighted.
