Abstract

The first opportunity to assess a largescale application of the PRECIS indexing system in North America came with its adoption by the National Film Board of Canada as the method of subject access to a national information system for Canadian audiovisual materials. The authors provide an overview of PRECIS use by this automated bibliographic service - the reasons for its choice, the challenge involved in the subject analysis and indexing of audiovisual documents, the methodology and software used to process PRECIS records, the resulting catalogue subject indexes and user reaction

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.
