摘要: Two novel techniques based on term expansion for domain-specific Word Sense Disambiguation are presented in this paper. A list of terms correlated with the ambiguous word is obtained by means correlation methods such as Pointwise Mutual Information and Chi-square. The used expanding context which an occurs, thus leading to a better number may be further determining correct sense target word. proposed method has been tested corpora (Finance Sports) one balanced corpus, British National Corpus (BNC). results competitive (Finance) ever (Sports BNC) than those reported previous works.
