Demonstrates the use of a directed graph model as a tool for finding desirable minimum vocabularies to be used in indexing and information retrieval. The basic algorithm is outlined, possible enhancements to the model are discussed, and further research questions are suggested. (Author/CLB)

Intended to facilitate the preparation of thesauri for the indexing of documents in any subject field, this report presents a set of rules pertaining to the complex issues and questions involved in indexing vocabulary development and construction. After a brief discussion of the nature, functions, and components of indexing vocabularies, a set of…

Construction planning, vocabulary base development, and term analysis and grouping are the main subjects treated in this paper. (NH)

Analysis of current methods for achieving compatibility or convertibility between two or more indexing languages draws attention to the need for a switching language to establish equivalency between concepts, not terms. In order to examine the assumption of the conceptual equivalency of identical terms in the indexing languages of related subject…
