| 摘 要： | 句子相似度计算在中文自然语言处理领域有着广泛的应用背景。要准确地刻画一个句子所表达的意思,必须深入到语义层面级并结合语法结构信息,提出了一种基于改进编辑距离和依存文法的汉语句子相似度计算方法。依存文法考虑到句子内部的结构和词语之间的相互作用关系,而编辑距离由于《同义词词林》的应用可以兼顾同义词之间的替换,因此该方法与其他方法相比,描述句子的信息更加全面,试验结果表明该方法是有效的。

| Abstract: | Sentence similarity computing has wide application background in the field of Chinese natural language processing.For describing accurately the meaning of a sentence,the deep study must be done at semantic level as well as considering its features of grammatical structure.The paper proposes an approach for computing sentence similarity based on Improved Edit-Distance and Dependency Grammar.Dependency Grammar refers to the structure inside a sentence and the relations among phrases and words,and Edit-distanc... |
