In this paper the GK` model for the construction of thesaurus classes based on fuzzy semantic association measure between index terms and concepts (thesaurus classes) is presented. The association measure is obtained on the basis of fuzzy semantic relations between

This paper discusses issues concerning the augmentation of thesaurus relationships, in light of new application possibilities for retrieval. We first discuss a case study that explored the retrieval potential of an augmented set of thesaurus relationships by specialising standard relationships into richer subtypes, in particular hierarchical geographical containment and the associative relation...

This paper relates preliminary results towards assessing the possible problems related to the reuse of existing thesauri for the search and retrieval of legal information. In particular, it focuses on the study of the Code of Federal Regulations and its related thesaurus, the Thesaurus of Indexing Terms.
