Semantic Clustering of Index Terms

A computer procedure to reorganize indexing vocabularies is described. Index terms are drawn from the vocabulary of a structured indexing system and may consist of single words, collections of words, or syntactic phrases. The basic idea is that a measure of the semantic association between index terms can be determined from the structural relationships which the terms exhibit by their relative positions in the system. The association measure, which is based on a priori (preassigned) semantic relationships between terms, rather than their co-occurrence in a document corpus, is then used for grouping index terms into clusters or concepts. Some results of an experimental investigation are presented. K E Y WORDS AND PHRASES: information, retrieval, clustering,
