English abstract

Presents a brief background of set theory relations including equivalence and ordering relations. Proposes four working hypotheses concerned with thesauri relations (USE, UF, NT, GS, BT & RT) and examines these relations against the characteristics of relations defined in Mathematics. Explores the possibility of generating equivalence class of descriptors from a single descriptor to aid information/ document retrieval. Provides a new mathematical approach to thesaurus and its relations and compares it with traditional way of representing thesaurus. Proposes new areas for investigation in this direction.
