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

The PRECIS system of subject headings was designed for use with a computer-produced subject index. Accordingly, the routines of subject heading work are clearly differentiated into clerical procedures and those that require judgement. The clerical procedures can be accomplished largely through the use of computer programs. The subject headings represent a unique combination of several different characteristics. As a result the system permits several coextensive forms of a subject name for each work. The allowable forms of subject name are restricted somewhat by the constraints of the system but the final choice amongst the various alternatives is made by the subject analyst. Often, this choice reflects his or her usage rather than any attempt to realize an explicit code for subject names. There is some evidence that this judgement varies in individual cases. Moreover, there is no empirical evidence that the alternatives permitted do reflect user convenience - although, in fact, this may be true

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 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.
