Abstract

One current trend in information retrieval that can facilitate resource sharing and cost reduction is the sread of common indexing languages. Of the more sophisticated languages available, clearly the best known and widely adopted is PRECIS. One of the claims made for PRECIS by its designer is that the role operators it uses correspond to linguistic universals, making PRECIS eminently suitable for multilingual indexing. This strong claim, if justified, could make PRECIS the common indexing language of choice where translation problems have high priority, as they do in Canada. This paper shows there is little support for this claim to universality because the role operators are defined in terms of superficial characteristics of language that are far from universal

Abstract

The efficiency of the role operators of PRECIS may be studied from two viewpoints - quantitative as well as qualitative. The frequency of appearance of different role operators in an input string may be taken as a measure of such quantitative parameters of efficiency. The scope of this paper lies in measuring the efficiency of role operators through their frequency of appearances in input strings. Most of the earlier research on PRECIS focused either on its general descriptions or its application to various subjects, media, languages, institutions, countries and to any regional/national/international information exchange network. No work has so far been reported which makes a quantitative evaluation of the system through its role operators except some general evaluative studies against different subject fields
