- Abstract
- Designing research on the retrieval effectiveness of computer searches on PRECIS compared with retrieval effectiveness of searches on other types of subject analysis used in computer-based information sources is a complex process. This paper explores the complexity of measuring comparative retrieval effectiveness through a comparison of the subject analysis provided by the PRECIS system for fifty articles with the subject analysis provided for the same articles by three computer-based information sources: ERIC/CIJE, LLBA/Online and PsycINFO. Objectives are: (1) to discover factors that should be taken into account when designing this type of research; and (2) to identify extraneous variables that work against internal validity in research design .

- 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

- Abstract
- When researchers at the Musée pour Rire, the international museum of humour in Montréal, Quebec, Canada, started to research film and video extracts for incorporation into the museum exhibits, it became obvious that a database with very specific subject access was necessary. A modified version of PRECIS, dubbed PRECIS-MO, was adopted. Discussed the adaptation and implementation

- Abstract
- PRECIS was introduced, mainly as an English language system, in the first paper in this series (1), and that account was followed by a generalised logicolinguistic explanation in the second (2). The present paper sets out to consider more practical matters of two kinds. Firstly, it describes some of the experiments in multilingual indexing which have been carried out already, noting in particular the lessons, leading to new procedures, drawn from these experiences. Secondly, the theoretical model proposed in the second paper, together with some of the new codes and procedures found to be necessary as the result of experiment with non-English languages, are related specifically to work in the Germanic languages.
