在自然语言中,动词的用法主要包含3种:字面、转喻和隐喻.动词的隐喻用法在隐喻的研究中占有重要的地位.动词的隐喻计算包含两个子任务:隐喻识别和隐喻理解.本文采用条件随机场、最大熵模型来识别动词的隐喻搭配,并在此基础上,加入了两种语义信息:《同义词词林》的同义词信息和《知网》的语义信息来识别动词的隐喻表达,实验识别正确率可达94.47%.
In a natural language, the expressions of verbs contain three types : literal, metonymic and metaphoric. Verb metaphor plays an important role in the field of metaphor study. The computing of verb metaphor can he divided into two subtasks: metaphor recognition and metaphor interpretation. This paper uses two models: Conditional Random Fields model and Maximum Entropy model to recognize verb metaphor. And in these basic models, this paper adds two kinds of semantic knowledge : synonymy information of Tongyici cilin and semantic information of HowNet to recognize verb metaphor. The accuracy of experiment reaches 94.47%.
