In natural language, the meaning of a lexeme often varies due to the specific surrounding context. Computational approaches to natural language processing can benefit from a reli- able, long-range-context-dependent represen- tation of the meaning of each lexeme that appears in a given sentence. We have devel- oped a general new technique that produces a context-dependent ‘meaning’ representation for a lexeme in a specific surrounding context. The ‘meaning’ of a lexeme in a specific con- text is represented by a list of semantically re- placeable elements the members of which are other lexemes from our experimental lexicon. We have performed experiments with a lexi- con composed of individual English words and also with a lexicon of individual words and selected phrases. The resulti...
