- 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
- 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
- This paper looks at the epistemological foundations of knowledge representations embodied in retrieval languages. It considers questions such as the validity of knowledge representations and their effectiveness for the purposes of retrieval and automation. The knowledge representations it considers are derived from three theories of meaning that have dominated twentieth-century philosophy.

- Abstract
- Historical account of the sophisticated method of indexing developed by J.O. Kaiser (1896/97), a librarian at the Philadelphia Commercial Museum who established his index on cards (a novelty then) and distinguished his items according to the categories 'concrete', 'process', and 'country'. He also introduced "statement indexing" and rules to this end in order to permit the supply of "complete information" on a subject in a document. In summarizing these findings, the author stresses the necessitiy of establishing well-defined categories if an organization of terms is to serve e.g. information retrieval.

- Rez. in: Knowledge organization 27(2000) no.3, S.173-175 (G. Campbell): "Bibliographic control rests on a rich and intriguing theoretical foundation. All too often, however, students and scholars of information studies pass this foundation over, perhaps because of its fragmentation. Information organization theory has evolved in tandem with practice, and particularly through innumerable policy decisions: its central tenets, therefore, appear in prefaces to manuals and catalogues, in library bulletins, in standards and rule interpretations, and in professional and scholarly conference proceedings. Gathering this theory together is a formidable task, and Svenonius has already made a significant contribution through the two sourcebooks she has coedited: Foundations of Cataloging (1985), and Theory of Subject Analysis (1985). With The Intellectual Foundation of Information Organization, 'Svenonius goes a huge step further: she pulls the fragments of bibliographic control theory together and sets them within a holistic theoretical framework. The result is a significant contribution to LIS scholarship, one which evokes the best of all possible responses: dissatisfied cries for more. Svenonius divides her treatise into two parts containing five chapters each. The first part provides a theoretically-grounded articulation of the objectives, entities, languages and principles of information organization. The field, she argues, rests on three distinct philsophical traditions. Systems philosophy, as developed in library circles by Charles Cutter, gives a holistic and visionary dimension to bibliographic control: a tendency to see individual processes as part of a larger, coherent structure. The philosophy of science, typified in the field by Cyril Cleverdon in the 1950s, emphasizes the need to quantify and generalize, and to subject the tenets of information retrieval to empirical verification. Language philosophy introduces the concept of language rules, and argues that information organization is a "particular kind of language use" (p. 6): an approach which enables us to employ linguistic concepts of semantics, vocabulary and syntax to explain the processes of information organization. Having established this framework, Svenonius goes on to discuss the objectives of bibliographic retrieval systems. Deftly combining the seminal contributions of Cutter, Seymour Lubetzky, the Paris Principles of 1961, and the IFLA objectives of 1997, she produces five central objectives of bibliographic control: locating entitles (finding), identifying entitles (collocating), selecting them (choice), acquiring or gaining access to them (acquisition), and navigating a bibliographic database (navigation) (p. 20)". -

- 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
