摘要: 在互联网上用户评价内容中很多比较句的比较结果反映了语句陈述者对比较对象的倾向性态度。根据已有的10类比较句句型总结了它们的常见概念搭配,在基于语义块的语句倾向性分析方法的基础上构建了比较句自动识别系统和比较句倾向性自动分析系统。采用第四届中文倾向性分析评测的语料进行实验,对语料中的比较句进行了识别,对比较句中的要素进行了抽取并且分析了比较句的倾向性,识别结果和倾向性分析结果均好于所有参评系统的平均值。

关键词: 用户评价,比较句,倾向性分析,概念搭配

Abstract: There are many opinions of narrators in the comparative results of comparative sentences which come from the content of user views on the internet.This paper summarized some usual conceptual collocations in ten kinds of comparative sentences.We proposed a method of recognizing comparative sentences and analyzing the opinion of a comparative sentence based on the semantic chunks of a sentence.An experiment was done by analyzing the corpus in the 4th Chinese Opinion Analysis Evaluation,which requires recognizing comparative sentences and analyzing the opinion and elements in a comparative sentence.The experimental results are both better than the average of all systems in the evaluation.

Key words: User views,Comparative sentences,Opinion analysis,Conceptual collocation
