WORDNET: A Lexical Database For English


WordNet is a lexical database for English organized in accordance with current psycholinguistic theories. Lexicalized concepts are organized by semantic relations (synonymy, antonymy, hyponymy, meronymy, etc.) for nouns, verbs, and adjectives. Work under this grant is intended to extend and upgrade WordNet, to make it generally available, and to develop it as a tool for use in practical applications. In order to make it available for information retrieval and machine translation, a system is being developed English text as input and automatically gives as output the same text augmented by syntactic and semantic anotations that disambiguate all of the substantive words. Initially, the semantic tagging is being done manually so that we can (1) obtain extensive experience with the tagging process and (2) create a database of correctly tagged text for use in testing proposals for automatic sense disambiguation.
