- 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
- This fourth paper in the series on PRECIS will consider the theoretical model of the indexing operation proposed in an earlier paper, and extend its application to one of the Romance languages, namely French. The present author has noted, throughout the publication of this series, how closely these logico-linguistic explanations could be applied to indexing in the French language. It is realised that experiments into PRECIS as a multilingual system are not complete, and that a new phase has undoubtedly started with the current British Library investigation of its translingual potential. Nevertheless, it would appear that the major problems still facing the researchers, such as the treatment of inflections, infixes, etc., are mostly related to the Germanic languages. As far as French is concerned, it is a relatively simple matter to give a positive answer to the question posed in the first paper: " . . . Do the codes and procedures developed so far (including the specified additions) amount to a general system which is capable of operating in any of the major European (and other) languages?"

- Abstract
- Probably the most interesting, original and controversial indexing system of the 1970s has been PRECIS (the Preserved Context Index System) developed by Derek Austin. It attracted such attention that the short courses given at the British National Bibliography offices in London -initiated as a means of teaching the staff of BNB who did subject indexing-were repeated all over the world, in the form of three-day or three-week sessions. A few fortunate non-BNB indexers were taken into London classes, taught by Austin and Digger, and had the advantage of a week's work with the regular staff theresomething that could not be done elsewhere. In addition, descriptions of the system were published from time to time as progress was made an the system itself and clarification or updating were needed. This article has been selected as an example of clarification. A second edition of the original 1974 Manual describing PRECIS appeared in early 1984, so the system may now be regarded as fully mature. PRECIS, which is the culmination of Austin's research for the Classification Research Group plus considerable additional input from the science of linguistics, is a highly sophisticated indexing system, deliberately created to be used with a computer. The motive behind it was that the indexer should do the brain work and the computer the nitty-gritty work of manipulating index terms. Chosen combinations and permutations are used as head words under strict rules to ensure that the context which defines the specific meaning of these words is always present, thus avoiding the ambiguity problem in indexing. The system also has classifi ation features, in part drawn from the Group's long interest in faceted classification. The actual index produces a large number of index entries, each carrying with it the basic context of the item being described. A weIl-defined terminology, in addition to contextdependency, is a feature of PRECIS. Role operators define the types of terms used and control the manipulations of the terms, which are originally entered as a string. The indexer is able to analyze and reduce to string form any document, process, or material that can be described in words, making it ideal for most audiovisual material.
