    Abstract
    Reviews the research that led to the development of a hierarchic scheme of terms with vocabulary control features, called Classaurus, and describes a project aimed at writing software that could be used for the automatic generation of an online alphabetic Classaurus. The problems encountered are discussed and suggestions for further research are made.

    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
    In continuation of an earlier critical discussion on the computerized Deep Structure Indexing System (DSIS), this paper presents some more of the same, concentrating on its term structure and cross reference entry structure.
