The chapters in this multidisciplinary volume reflect contemporary research into principles of lexical and semantic organization. Past years have seen much progress in the study of language in understanding the systems of phonology and syntax. The analysis of individual words has been undertaken by lexicography and philology, but the global organization of vocabularies of natural languages has not received comparable attention. Recently, there has been a surge of interest in the lexicon. The demand for a fuller and more adequate understanding of lexical meaning required by developments in computational linguistics, artificial intelligence, and cognitive science has stimulated a refocused interest in linguistics, psychology, and philosophy.
