语义相关度计算作为中文信息处理领域中的一项关键技术,在信息检索、语义消岐、文本分类中起着重要的作用。利用汉语复句的句法理论和关系标记搭配理论,以汉语复句语料库以及搜索引擎获取的复句为语料,提出了一种基于汉语复句的语义相关度计算方法—SRCCS。本方法不仅能够计算词语的相关度,而且能够表明相关的性质与类别。与通过短文计算相关度的方法相比,本方法选取的计算对象范围更小,因而结果更准确,计算复杂度更低。在同一测试集上与搜索引擎方法的对比分析证明了基于汉语复句的语义相关度计算方法的有效性与优越性。

As a critical technique in the field of Chinese information processing, word semantic relevancy computation plays an important role in information retrieval, ambiguity elimination, and text processing. Using syntactic theory and the collocation theory of the relation markers of Chinese compound sentences, as well as making the corpus of Chinese compound sentences and some compound sentences from search engine as the data resource, a semantic relevancy com- putation method was proposed based on Chinese compound sentence （SRCCS）. This method ca...
