Text mining and Natural Language Processing software usually integrate lexical resources like WordNet, a lexical database for the English language, developed starting from 1985 by the Princeton University, department of Psychology, under the direction of George A. Miller. WordNet groups nouns, verbs, adjectives and adverbs into sets of cognitive synonyms, each expressing a distinct concept. The concepts are interlinked by means of conceptual-semantic and lexical relationships.
