The practical outcome of the project,Analysis of the Organization of Lexical Memory, is an electronic lexical database called WordNet that can be incorporated into computer systems for processing English text. WordNet includes approximately 45,000 lexicalized concepts, providing a coverage equivalent to a handheld dictionary. The database has three components, one each for nouns, verbs, and adjectives. The semantic relations that organize each component are different, but in general a lexicalized concept is represented by a set of synonyms that can be used to express the concept, the familiar semantic relations are presented by labeled pointers between synonym sets. In order to create the database, programs were written to write and edit lexical files, to convert lexical files into a database, to search the database, to strip inflections from search requests, and to display retrieved information for a user.
