Abstract

Information search and retrieval interactions usually involve information content in the form of document collections, information retrieval systems and interfaces, and the user. To fully understand information search and retrieval interactions between users' cognitive space and the information space, researchers need to turn to cognitive models and theories. In this article, the authors use one of these theories, the basic level theory. Use of the basic level theory to understand human categorization is both appropriate and essential to user-centered design of taxonomies, ontologies, browsing interfaces, and other indexing tools and systems. Analyses of data from two studies involving free sorting by 105 participants of 100 images were conducted. The types of categories formed and category labels were examined. Results of the analyses indicate that image category labels generally belong to superordinate to the basic level, and are generic and interpretive. Implications for research on theories of cognition and categorization, and design of image indexing, retrieval and browsing systems are discussed.

Abstract: The book is about knowledge structures as found in information handling tools, classification and indexing systems, as represented in the human mind and in artificial intelligence systems. It looks at the concepts and relationships in these structures

Abstract

Based on a paper presentend to the Documentation Research and Training Centre 'Seminar on classification and indexing in social sciences', Bangalore. An analysis of a detailed survey on facet-analysed subject strings in the field of social sciences. Subject strings of 4 typers were administered as a stratified sample of responses to identify the gaps in semantic connotation of terms. This survey has helped to idetify the possible aberrations in the semantic connotations due to the presence or absence of terms. It was found that use of prepositions, conjunctions and other role indicating terms gives semantic clarity. The syntax of speciator terms may have to be varied according to the respondent groups. It was found that if the number of component terms in a subject string increases beyond a certain limit it gives rise to problems in interpretation of ideas. This indicates a break-even point for formulating subject headings
