摘　　要：在自然语言处理中,多义疑问词的词义识别尚存改进空间。以"怎么"为例,其可表全称解读(任指)、存在解读(虚指)和疑问解读(询问状况、性状、方式和原因)。目前主流机器翻译系统在处理"怎么"的识别情况上仍需改进。该文从词义排歧的角度出发,尝试总结"怎么"的三类解读所处的句法环境的特征,确立复杂句法环境中其语义表现,进而构建一个基于规则的词义排歧模型,制定词义排歧决策表,为提高机器对该类词的识别率提供一种思路。最后,通过实验验证该决策表,并对其改进。There are at least six interpretations of wh-phrase zenmein Mandarin Chinese:universal implication,existential implication and interrogative implication(including 4 sub-division of situation,character,manner,reason).This paper proposes a rule-based approach to recognize zenme’s interpretations in different syntactic contexts.On the basis of the summarization of the syntactic contexts of the different complications,a word sense disambiguation model of zenmeis proposed.The rule based method is validated and finally optimized by experiments.
