Abstract

The terms which comprise an entry in an index can be arranged in various ways. The use use roles or facets such as 'thing-action-part-effect' under which terms can be categorized allows the use of citation orders which preserve the syntactic relationships between terms in a string. Alphabetization and rotation in context are simple methods but with certain disadvantages for the users. The citation order of BTI results in a detailed index using punctation to indicate relationships. PRECIS incorporates prepositions which preserve necessary entries. Articulated indexes use natural language phrases displayed under selectes subject headings. These methods could be used to construct book indexes

Abstract

The Preserved Context Index System (PRECIS) developed for subject indexing for the BNB is discussed as a basis for various studies relating to classification which could be made from its initial phrases, strings, entries and back-up structure. Specific possibilities include use of mehodologies such as Goffman's "indirect method", Fox's "characterization" of rules, derivation of empirical hyperbolic distributions, and lognormal distributions. The relationship of existing methods of subject analysis to each other through PRECIS is explored. Brief samples are included

Abstract

Report on research carried out in Brazil for a doctoral thesis, investigating the possibility of using the PRECIS indexing system for documents in Portuguese. Discusses the theoretical basis of PRECIS, and presents the resultss of a study in comparing the use PRECIS to index 2 samples of documents, in English and Portuguese respectively. Concludes that, with minor modifications to take account of the differences in structure between the 2 languages. PRECIS could produce satisfactory results for documents in Portuguese. This suggests the further possibility that PRECIS - because of its sound logical basis rather than its complex linguistic theory - could become a multilingual indexing system.

Abstract

The present paper is offered as the first of a series of articles in which PRECIS will be reviewed as a potential multi-lingual system, having in mind the obvious need, notably in a European context, for standard and language independent methods of subject analysis and document description. This first paper outlines the origins of PRECIS, and considers its use in English language indexing. A second paper will deal in general terms with the syntactical model which is used for producing PRECIS input strings and index entries. Later papers will then review the application of this model to indexing in, firstly, the Germanic languages (e.g. German and Danish), and, secondly, the Romance languages, illustrated by French.

Abstract

In this second paper in the series on PRECIS we set out to establish a theoretical model of the indexing operation to account for the growing empirical evidence that PRECIS can be applied successfully to the terms and phrases of more than one natural language (NL). For this purpose, the system is examined from two different but related viewpoints, the first linguistic and the second logical. In linguistic terms, the schema of role operators is related to certain features of NL which are regarded by linguists as language-independent, particular attention being paid to Chomsky's 1965 theory, the notion of deep cases, and the idea that roles, as used in an indexing language (IL) are related to deep cases in NL. It is realised that we should not rely too heavily on analogies between NL and IL, on the grounds that these two kinds of language have different structures and to some extent different functions, Consequently, the structure of a PRECIS string is also considered in terms of an alternative logic, and it is suggested that the order of terms in strings and entries, explained in the earlier paper through reference to the dual properties of context-dependency and one-toone relationships, is also amenable to a different but reinforcing explanation in terms of time-dependency. These two types of explanation, the linguistic and the logical, form the basis for a proposed theoretical model of the 'stages of indexing'. Finally, the authors consider the implications of this model for multilingual indexing.
