The Thesaurus is the alphabetically or topically structured vocabulary. The terms in a thesaurus are grouped together according to similarity of meaning or domain of knowledge, and are interconnected by semantic relations such as synonym, antonym, hypernym (generalization), hyponym (specification), etc.
There are thesauri with word definitions, or/and translations, monolingual and multilingual. Thesauri are used in many applications including information retrieval and natural language processing, for example for identifying the synonyms and other semantically similar related terms for indexing online material or for text analysis applications.
