The effectiveness and efficiency of five index languages in the subject area of library and information science are compared. Full details of the text and retrieval results are presented. (17 references) (Author/NH)

The index term input to three information retrieval systems has been analyzed in detail in order to form the input to a completely computerized simulation of an information retrieval system. The paper reports that, with certain reservations, index terms conform in general with the Bradford distribution. (Author)

Symbols for bibliometric concepts like "half life,""impact factor,""normalized impact factor," and "immediacy index" are proposed and formulas for the determination of their values are provided. The features of the bibliometric concepts are also highlighted. (Author/AEF)

Reviews different structures and techniques of knowledge representation: structure of database records and files, data structures in computer programming, syntatic and semantic structure of natural language, knowledge representation in artificial intelligence, and models of human memory. A prototype expert system that makes use of some of these…

Argues that indexing and classification schemes rely on an understanding of "subject" and discusses several different conceptions of subject as epistemological positions. It is further argued that a theory of subject must be based in a theory of knowledge, and a theory based on a realistic/materialistic epistemology is proposed. (39…

Explains some major problems related to the subject indexing process and proposes semiotics as a framework for understanding the interpretive nature of the process. Explores the approach to studies of indexing and library and information science suggested by Fairthorne, Blair, Benediktsson, and others. Offers an explanation of what occurs in the…

This review of the literature discusses theories of information with emphasis on the views of Dervin and Popper on subjectivity and objectivity as they relate to information use. Classification and indexing as applied in information retrieval systems and libraries are also discussed, and 78 references are provided. (LRW)

A series of articles reviews the contributions of Brian Campbell Vickery and current research extending this work. Topics covered include the role of classification in information retrieval, social scientists' information needs, national document supply and catalog entry supply in Britain, and research and development in the United Kingdom.

A survey of recent publications shows that frequent topics of Internet and information retrieval research are the effectiveness of search engines, information validation and quality, user studies, design of user interfaces, data structures and metadata, classification and vocabulary based aids, and indexing and search agents. The changing balance…
