- Abstract
- The study of faceted classification systems has primarily been directed towards application for precombined catalogues or bibliographies, not so much for use in post coordinated retrieval systems. Argues that faceted classification systems in some respects are superior to other techniques of on-line retrieval as far as facet and concept analysis is combined with an expressive notational system in order to guide a form of retrieval which will use Boolean operators (for combining the facets regardless of one special citation order) and truncation for retrieving hierarchically different sets of documents. This point of view is demonstrated by 2 examples. The 1st one uses a short classification system derived from B. Buchanan and the 2nd is built upon the classification system used by Library and Information Science Abstracts (LISA). Further discussion is concerned with some possible consequences which could be derived from a retrieval with PRECIS strings
"Online retrieval" conjures up a very different mental image now than in 1991, the year this article was written, and the year Tim Berners-Lee first revealed the new hypertext system he called the World Wide Web. Gödert shows that truncation and Boolean logic, combined with notation from a faceted classification system, will be a powerful way of searching for information. It undoubtedly is, but no system built now would require a user searching for material on "nervous systems of bone fish" to enter "Fdd$ and Leaa$". This is worth reading for someone interested in seeing how searching and facets can go together, but the web has made this article quite out of date.

- Abstract
- Results of a survey of North Carolina Libraries revealed that of 91 respondents, 29 had on-line catalogues. Of the libraries with on-line catalogues, 11 used the Dewey Decimal Classification (DDC). Survey findings indicate that the DDC has limited use in on-line searching today.

- Abstract
- Subject retrieval by Library of Congress (LC) Classification numbers is examined from the perspective of 5 user groups of on-line catalogues. Although, at present, librarians are the user group most likely to benefit from the LC classification advances in the capabilities of on-line catalogues. Research on the use of the LC classification schedules as a component of subject retrieval should continue.

- Abstract
- Purpose - To suggest that a theory of classification for information retrieval (IR), asked for by Spärck Jones in a 1970 paper, presupposes a full implementation of a pragmatic understanding. Part of the Journal of Documentation celebration, "60 years of the best in information research". Design/methodology/approach - Literature-based conceptual analysis, taking Sparck Jones as its starting-point. Analysis involves distinctions between "positivism" and "pragmatism" and "classical" versus Kuhnian understandings of concepts. Findings - Classification, both manual and automatic, for retrieval benefits from drawing upon a combination of qualitative and quantitative techniques, a consideration of theories of meaning, and the adding of top-down approaches to IR in which divisions of labour, domains, traditions, genres, document architectures etc. are included as analytical elements and in which specific IR algorithms are based on the examination of specific literatures. Introduces an example illustrating the consequences of a full implementation of a pragmatist understanding when handling homonyms. Practical implications - Outlines how to classify from a pragmatic-philosophical point of view. Originality/value - Provides, emphasizing a pragmatic understanding, insights of importance to classification for retrieval, both manual and automatic. - Vgl. auch: Szostak, R.: Classification, interdisciplinarity, and the study of science.

- Abstract
- Librarians are often so eager to adopt new technologies and systems that they can lose sight of the realities that must be dealt with. Among factors that may delay use of Dewey Decimal Classification (DDC) for on-line catalogues retrieval are: limited use of DDC in libraries with operational on-line catalogues; limitations to the MARC bibliographic formats: lack of an authority structure for classification number for items catalogued. Factors that may delay development of effective classification retrieval mechanisms include unclear terminology and unreasonably high (or low) expectations.

- Abstract
- Conceptual Knowledge Markup Language (CKML), an application of XML, is a new standard being promoted for the specification of online conceptual knowledge (Kent and Shrivastava, 1998). CKML follows the philosophy of Conceptual Knowledge Processing (Wille, 1982), a principled approach to knowledge representation and data analysis, which advocates the development of methodologies and techniques to support people in their rational thinking, judgement and actions. CKML was developed and is being used in the WAVE networked information discovery and retrieval system (Kent and Neuss, 1994) as a standard for the specification of conceptual knowledge

- Abstract
- There is every indication that classification systems which are international in their use, and free from the impact of national languages, will be given strong consideration as the choice for an information retrieval language in an automated environment. The aims of the Symposium were: to provide a forum for discussion of the problems and opportunities emerging from MARC records; to reconsider intellectual level as a significant determinant of information retrieval; and to explore the potential of the Dewey Decimal Classification and the Library of Congress Classification systems as information retrieval languages in an on-line environment.

- Abstract
- Free text searching with keywords in a complete data store is not necessarily the best automatic retrieval method. There must be a proper classification of documents and concepts and the use of a proper classification system avoids problems of terminological deficiency. The dialogue search form makes the on-line catalogue a new information medium. A bibliographic unit must be created with as many search access points as possible, using verbal and classificatory search elements. Verbal search categories must include free text elements for individual search access requirements and a controlled vocabulary with syntactic connections. Classified data should consist of a universal classification system with clear structural notation for access and surface searching, together with several specialist subject classifications for differentiated documentation and retrieval. The universal classification needs no detailed subdivision: it serves mainly as a guide and entry to the detailed sub-systems

- Abstract
- Modern fact databses contain abundant data classified through several classifications. Typically, users msut consult these classifications in separate manuals or files, thus making their effective use difficult. Contemporary database systems do little support deductive use of classifications. In this study we show how deductive data management techniques can be applied to the utilization of data value classifications. Computation of transitive class relationships is of primary importance here. We define a representation of classifications which supports transitive computation and present an operation-oriented deductive query language tailored for classification-based deductive information retrieval. The operations of this language are on the same abstraction level as relational algebra operations and can be integrated with these to form a powerful and flexible query language for deductive information retrieval. We define the integration of these operations and demonstrate the usefulness of the language in terms of several sample queries

- Abstract
- This response to the paper by Dr. Chan, while accepting the merits of call number searching in the theoretical sense, raises questions about its usefulness in typical library situations. Compares searching on-line with call numbers and the use of classified catalogues and shelflists. Asks who is expected to do call number searching. Considers the availability of indexes to the classification scheme, problems created by the provision of only 1 class number per document, and the use of multiple cutter numbers to express the subject of a document.

- Abstract
- This paper examines some traditional information searching methods and their role in Hungarian OPACs. What challenges are there in the digital and online environment? How do users work with them and do they give users satisfactory results? What kinds of techniques are users employing? In this paper I examine the user interfaces of UDC, thesauri, subject headings etc. in the Hungarian library. The key question of the paper is whether a universal system or local solutions is the best approach for searching in the digital environment.
