基于HowNet句子相似度的计算
Calculation of Sentence Similarity Based on HowNet
摘要
Abstract
Chinese sentence similarity computation is a fundamental and important work in the natural language processing. It directly de-termines the status of research and development for certain related fields. Based on the word similarity computing,for the shortcoming of current sentence similarity computing methods,present a method to compute sentence similarity Based on HowNet. Based on the lexical semantic similarity calculation of HowNet,antonyms,negative single sememe,symbol sememe,and definition information are demonstra-ted to calculate word similarity. In this method,word disambiguation is completed before the calculation of sentence similarity. The situa-tion of the similarity between the relation sememe of a word definition and a certain sememe of the given word are considered,and the re-lation sememe weight is added. Under the same test conditions,the experimental results show that the proposed method can improve the computational accuracy of sentence similarity and it is much closer to the people' s comprehension to the meanings of the sentences.关键词
