Abstract

Investigates current thinking on the theory and application of index language. Explains their links with on-line retrieval systems and the need to go beyond a narrow library application, identifying 2 regularly occurring points of view: transferring traditional ideas about conventional keyword catalogues to post-coordinate on-line searches and redundant terminology about input and its replacement by pure subject searching. Explores the general subject literature, the theory of verbal documentation languages, syntactical indexing, the thesaurus principle and faceted classification structure

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for someone interested in seeing how searching and facets can go together, but the web has made this article quite out of date.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

In this paper a model for understanding the concept of information is presented and how the processes of externalization and perception of information by human beings could be understood. This model is different from the standard information theoretic model. It combines the understanding of cognitive information processing as an act of information generation from sense impressions with communication theoretic considerations. This approach can be of value for any system that is regarded as a knowledge system with an in-built ordering structure. As an application some consequences will be drawn for the design of information systems which claims to handle information itself (e.g. multimedia information systems) instead of giving references to bibliographic entities

Abstract

Identifies the interest in questions of classified catalogues generated by the development of on-line catalogues, establishing a difference between 2 large areas: free access to information items in a systematic arrangement and expressing the contents of books by means of notational symbols in a classification system in a local catalogue. Examines the elements and structure of classification systems, the internationally important universal classifications, the procedures for book display and systematic processing in West German public libraries and exhibtion techniques in West German academic libraries. Covers universal and faceted classifications, as well as classification systems in on-line catalogues

Abstract

Since the introduction of Regeln fur den Schlagwortkatalog (RSWK - Subject Cataloguing Rules) and the arrival of online public catalogues, librarians might ask whether number building is essential or whether the same result could be achieved with Boolean operators. Descriptive categories could be prepared, with word or phrase inversion, as a retrieval system component. The role of syntactic indexing in online retrieval and consequences for service interface ...
