- Abstract
- Farradane's theory of relational analysis has wide applications in information retrieval. The major areas of application cover their use in retrospective searches, semantic analysis of information, concept organisation and control, efficiency as an information retrieval tool, multilingual indexing tool, in SDI term relations in thesauri, study of nature of subjects, computerised indexing systems, analysis and measuring of information and organisation of current information. Most of the applications were in scientific subjects and the data bases considered were too small to generalise. Suggests 5 new areas of research on relational indexing: compilations of a detailed manual; application in scientific, social sciences, and humanities literature; application in study of the nature of subject literature; comparative efficiency of relational indeximg; and a compilation of a relational thesaurus.

- 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
