Abstract

NLP methods and applications need to take account not only of "classical" lexical relations, as found in WordNet, but the less-structural, more context-dependent "non-classical" relations that readers intuit in text. In a reader-based study of lexical relations in text, most were found to be of the latter type. The relationships themselves are analyzed, and consequences for NLP are discussed.
