Study of chinese word sense disambiguation based on scenario words

摘要

Word sense disambiguation (WSD) is the hot and difficult issue in natural language processing. Feature selection is the major factor that influences WSD. Different disambiguation methods selected different characteristics. Because the word in the context influences the polysemous disambiguation results, we proposed the concept of scenario word. Scenario words play different roles when we use them to determine the meaning of polysemy. We divide scenario words into co-occurrence words, collocations and demonstratives. Through the experiment, we test the feasibility of the method.
