Abstract

The advent of the computer has brought epistemological questions, heretofore the province of classificationists and philosophers, into the limelight of popular thought. No longer of only theoretical interest, such questions stand in need of operational answers, at least if computers are to process information intelligently. Answers to these questions are embodied in what today are known as knowledge representations. Knowledge representations are used for a variety of related purposes, including language and text understanding, cognitive research, expert system development and information retrieval. This paper focuses on the use of three computer-based knowledge representations of potential relevance for information retrieval: hypertext systems, cluster analysis and knowledge representations accomodating rule-based reasoning. It then considers research that might be pursued to inform the development of knowledge representations for information retrieval

Abstract: The issue of free-text versus controlled vocabulary is examined in this article. The history of the issue, which is seen as beginning with the debate over title term indexing in the last century, is reviewed and the attention is turned to questions which have not been satisfactorily addressed by previous research. The point is made that these questions need to be answered if we are to design retrieval tools, such as thesauri, upon a national basis

Abstract

This paper looks at changes affecting LCSH over its 100-year history. Adopting a linguistic conceptualization, it frames these changes as relating to the semantics, syntax and pragmatics of the LCSH language. While its category semantics has remained stable over time, the LCSH relational semantics underwent a significant upheaval when a thesaural structure was imposed upon its traditional See and See also structure. Over time the LCSH syntax has become increasingly complex as it has moved from being largely enumerative to in large part synthetic. Until fairly recently the LCSH pragmatics consisted of only one rule, viz, the injunction to assign specific headings. This rule, always controversial, has become even more debated and interpreted with the move to the online environment
