- 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
- Reports the results of research designed to explore the feasibility of automatically deriving name access points from machine readable title pages of English language monographs. Results show that approximately 88% of the access points selected by the Library of Congress or the National Library of Medicine could be automatically derived from title page data. These results have implications for the design of bibliographic standards and on-line catalogues.

- Abstract
- An examination of some nonbook materials with respect to an aboutness model of indexing leads to the conclusion that there are instances that defy subject indexing. These occur not so much because of the nature of the medium per se but because it is being used for nondocumentary purposes, or, when being used for such purposes, the subject referenced is nonlexical

- Abstract
- A model system, the Dewey Online Retrieval System (DORS), was implemented as an interface to an online catalog for the purpose of experimenting with classification-based search strategies and generally seeking further understanding of the role of traditional classifications in automated information retrieval. Specifications for a classification retrieval interface were enumerated and rationalized and the system was developed in accordance with them. The feature that particularly distinguishes the system and enables it to meet its stated specifications is an automatically generated chain index

- Abstract
- Key problems of subject searches in online public access catalogs are that too much may be retrieved and that the display may be arranged in what appears to be an unintuitive and unhelpful manner. A study was undertaken on one large database to determine how often the display of a subject and its modifications and subdivisions extended over more than two screens and what the results on display would be of compressing geographic subdivisions and other modifications. The study then addressed the question of how often the display of a term and its subdivisions was interrupted by the appearance in the display of inverted headings, phrase headings, and headings with parenthetical qualifiers

- 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 article discusses some of Ranganathan's contributions to the productive, practical and theoretical aspects of classification science. These include: (1) a set of design criteria to guide the designing of schemes for knowledge / subject classification; (2) a conceptual framework for organizing the universe of subjects; and (3) an understanding of the general principles underlying subject disciplines and classificatory languages. It concludes that Ranganathan has contributed significantly to laying the foundations for a science of subject classification.

- Abstract
- Reports results of a project to explore ways of reconfiguring AACR2 for use in an automated environment. A subset of AACR2 title proper rules for books was chosen for analysis. A functional classification of the rule subset was developed, based on the 4 facets: Source, Choice, Form, and Definition. The rules were also classified according to whether they were core or peripheral. A prototype electronic interface was developed for searching and displaying the classified rules. The greatest problem in the rule reconfiguration stemmed from the structural problems of AACR2: rule groupings combining multiple subfacets under a single rule; rule redundancy; and rule scatter, between chapters, and between sections of chapters and appendices

- Abstract
- The last several years have seen the evolution of prototype systems exploiting the use of the Dewey Decimal Classification (DDC) as an interface to online catalogs. One such system, calles DORS (Dewy Online Retrieval System) was developed at the University of California, Los Angeles by the authors. The feature distinguishing this system is an automatically generated chain index, in particular the algorithms that were created for its automatic generation and the problems that were encountered. The problems were of three kinds: those that were overcome, but were not for lack of time and resources and those that we believe cannot be overcome. The paper concludes with suggestions for future resaerch and possible formatting changes to the DDC feature headings that would facilitate chain-index generation

- Abstract
- Classification research at any point in time is the resultant product of various philosophical, technological, social, economic, and political forces. This address attemps first to give a partial description of the present state of classification research as determined by one of these forces: philosophy, in particular the 20th century analytic philosophies of logical positivism, linguistic analysis and systems analysis; and, second, assuming the continued influence of these, to speculate upon the future of classification research in terms of its prospects, problems and possibilities

- Abstract
- Recent papers have called attention to discrepancies in the assignment of LCSH. While philosophical arguments can be made that subject analysis, if not a logical impossibility, at least is point-of-view dependent, subject headings continue to be assigned and continue to be useful. The hypothesis advanced in the present project is that to a considerable degree there is a clear-cut right and wrong to LCSH subject heading assignment. To test the hypothesis, it was postulated that the assignment of a subject heading is correct if it is supported by textual warrant (at least 20% of the book being cataloged is on the topic) and is constructed in accordance with the LoC Subject Cataloging Manual: Subject Headings. A sample of 100 books on scientific subjects was used to test the hypothesis

- Abstract
- Die Diskussion um Vor- und Nachteile von Präkoordination oder Postkoordination wird unter den in der verbalen Sacherschließung Engagierten in Deutschland seit Jahren geführt. Mit zunehmender Verbreitung der RSWK gewinnen die Überlegungen, die sich angesichts der Ausbreitung des OPAC für das 'Zerschlagen' der Schlagwortketten aussprechen, an Bedeutung. In diesem Zusammenhang trägt eine Berücksichtigung der internationalen Debatte um Prä- und Postkoordination zur Erweiterung des nationalen Horizontes bei. Der Beitrag ist eine leicht gekürzte Übersetzung eines Referates, das die Autorin beim IFLA Satellite Meeting zum Thema 'Subject indexing in the 90's - principles and practices' im August 1993 in Lissabon gehalten hat
