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

Starting from an unsolved problem of information retrieval this paper presents an ontology-based model for indexing and retrieval. The model combines the methods and experiences of cognitive-to-interpret indexing languages with the strengths and possibilities of formal knowledge representation. The core component of the model uses inferences along the paths of typed relations between the entities of a knowledge representation for enabling the determination of hit quantities in the context of retrieval processes. The entities are arranged in aspect-oriented facets to ensure a consistent hierarchical structure. The possible consequences for indexing and retrieval are discussed.

Abstract

The presented ontology-based model for indexing and retrieval combines the methods and experiences of traditional indexing languages with their cognitively interpreted entities and relationships with the strengths and possibilities of formal knowledge representation. The core component of the model uses inferences along the paths of typed relations between the entities of a knowledge representation for enabling the determination of result sets in the context of retrieval processes. A proposal for a general, but condensed, inventory of typed relations is given. The entities are arranged in aspect-oriented facets to ensure a consistent hierarchical structure. The possible consequences for indexing and retrieval are discussed.

Abstract

Examines the advantages and disadvantages of precoordinated, postcoordinated and automatic indexing with regard to existing information storage systems, such as card catalogues, OPACs, CR-ROM databases, and online databases. Presents a general model of document content representation and concludes that the library profession needs to address the development of databank design models, relevance feedback methods and automatic indexing assessment methods, to make indexing more effective

Abstract

The test ran between Nov 95-Aug 96 in Cologne Fachhochschule fur Bibliothekswesen (College of Librarianship).The test basis was a database of 190,000 book titles published between 1990-95. MILOS II mechanized indexing methods proved helpful in avoiding or reducing numbers of unsatisfied/no result retrieval searches. Retrieval from mechanised indexing is 3 times more successful than from title keyword data. MILOS II also used a standardized semantic vocabulary. Mechanised indexing demands high quality software and output data

Abstract

The research, investigating experiences of users with subject searching of on-line public access catalogues (OPACs), stresses that there is an interaction between: features of the indexing languages used; indexing principles used; design and structure of the data base; and the possiblities of the technical retrieval faculty, search mode and query language used

Abstract

We present an approach for detecting multiword phrases in mathematical text corpora. The method used is based on characteristic features of mathematical terminology. It makes use of a software tool named Lingo which allows to identify words by means of previously defined dictionaries for specific word classes as adjectives, personal names or nouns. The detection of multiword groups is done algorithmically. Possible advantages of the method for indexing and information retrieval and conclusions for applying dictionary-based methods of automatic indexing instead of stemming procedures are discussed.

Abstract

Experiences with retrieval in OPACs suggest that there are major problems for the users of such systems, such as choosing the 'correct' subject access vocabulary, narrowing or broadening the set of items retrieved regarding the search interest. Such problems relate to two facts: (1) that in the early OPACs subject access has not been considered seriously enough and (2) that the complexity of the topic has not been really recognized. Using a typology of users' questions it is demonstrated which requirements musts be met by a successful online subject access. Improvements of subject access tools are primarily aimed at, pinpointing the interplay between the different subcomponents of any subject facility: a) the features of the indexing languages used; b) the indexing principles used; c) the design and structuring of the database; and d) the possibilities of the technical retrieval facility, the search mode, and query languages. The contribution summarizes the manifold interactions between the four subcomponents listed. Any successful retrieval will heavily depend on the design of these components considering their interactions.

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

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 ...

Abstract

This paper presents a new approach to understanding how indexing strategies, models for interoperability and retrieval paradigms interact in information systems and how this can be used to support the design and implementation of components of a semantic navigation for information retrieval systems.

Abstract

Analyses mathematical terminology to give practical hints for assigning subject headings to a book and proposes a method to use for subject analysis. The method is based on connections between the subject-classification scheme of the American Mathematical Society and indexing with subject headings. Gives examples and compares them with LCSH and PRECIS. A thesaurus of mathematics, using PRECIS methods and connecting with the Amercian Mathematical Society classification is desirable. Authors could also classify their own work and the data could be printed with the books
