INTERACTIVE RELATIONS BETWEEN SEMANTIC AND SYNTACTIC FEATURES IN WORD SENSE DISAMBIGUATION OF SEMANTICALLY COMPLEX WORDS

摘要

The interactions between the semantic and syntactic features in the word sense disambiguation (WSD) of semantically complex words are studied in this paper. A structural partial-ordered attribute diagram (SPOAD) is generated for the WSD of English secondary modal verb "should", and the accuracy of WSD reaches 98%. Some rules are extracted from the SPOAD for WSD of "should", and the accuracy of WSD by the rules reaches 97%. The discovered interactive relations between semantic and syntactic features in WSD and contributions of the features to WSD provide significant and valuable evidence for the proper feature selection in natural language processing, decision making of modality in information processing and semantic study of English modal verb and other semantically complex words.
