A New Exploration into Word Sense Induction

Existing study in word sense induction(WSI)from linguistic perspective need further improvements in systemacity, principle, and methods. The following measures are used to improve existing studies:(1)WSI is carried out against the background of linguistic ontology; (2)WSI is carried out according to the part of speech of words, certain steps, and parameters, and refferring to valency theory, event type theory, and qualia structure theory of the Generative Lexicon. A principle is offered to decide on the sense number of a word and 3 standards are offered for WSI. Studies show that operatability, completeness and discreteness of WSI are improved obviously.
