基于合作网的汉语句子隐喻理解

Chinese Sentential Metaphor Comprehension Based on Cooperative Network Model

我们的认知思维和概念系统建立在隐喻之上.隐喻理解的实现,是自然语言处理任务中关键的一环.为了让理解过程更好地切合隐喻的工作机制,基于隐喻的互动理论,提出了合作网模型,将隐喻理解的过程部署为一个网状结构,实现汉语句子隐喻的理解计算.相比于其他模型,合作网模型体现了目标域和源域之间“求同存异”的语义关系,强调概念之间的双向语义联结,通过计算各个关系的强弱,输出更适应于上下文信息的表述意义.实验结果表明,合作网模型合理、有效.基于合作网得到的理解结果,能够初步反映隐喻理解过程的动态性和突显性.

Chinese cognition and conceptual system is built on metaphors.Metaphor comprehension is an important task in natural language processing.Based on the interaction theory,the cooperative network model(CNM)is proposed,which better conforms to the character of metaphor,to perform metaphor comprehension.The CNM reveals the semantic relations between target and source domain,i.e.,seeking common ground while reserving differences.Besides,the CNM addresses bidirectional semantic relations between concepts.By computing cooperative strength of relations,the CNM obtains the meaning of metaphorical context.The experimental results demonstrate the effectiveness of the CNM.The outputs of the CNM preliminarily reflect the dynamic and prominent mechanisms of metaphor comprehension.
