Lexical Functions and Their Applications
As a concept, lexical function (LF) was introduced in the frame of the Meaning-Text Theory (MTT) presented in (Mel’čuk, 1974, 1996) in order to describe lexical restrictions and preferences of words in choosing their “companions” when expressing certain meanings in text. Here we will give a brief account of the fundamental concepts and statements of MTT as the context of LFs. Actually, the formalism of lexical functions has been one of those parts of MTT which attracted most attention of specialists in general linguistics and, in particular, computational linguistics. A lot of research began in the area of natural language processing with the purpose to develop various approaches and techniques of employing LFs in such applications as word sense disambiguation, computer-assisted language learning, machine translation, text paraphrases, among others.
