Abstract

Review of various approaches to automatic thesaurus formation and presentation of the SEXTANT system to analyse text and to determine the basic syntactic contexts for words. Presents an automated method for creating a first-draft thesaurus from raw text. It describes natural processing steps of tokenization, surface syntactic analysis, and syntactic attribute extraction. From these attributes, word and term similarity is calculated and a thesaurus is created showing important common terms and their relation to each other, common verb-noun pairings, common expressions, and word family members
