目前主流的评价搭配抽取方法以句法依存分析为基础，由于中文评价文本的不规范性，导致其句法分析结果不稳定，进而影响评价搭配的抽取效果。针对该问题，提出一种改进的基于核心句的评价搭配抽取方法。设计融合核心句和句法依存关系的评价搭配抽取方法，提高评价语句句法分析结果的稳定性，并且在处理复杂的评价语句时，加入对评价对象之间、情感词之间并列关系的分析。实验结果表明，该方法能提高召回率和准确率。

The mainstreaming evaluation collocation extroction methods are based on syntactic dependency parsing. Because the grammar of most Chinese evaluation text is not normative,the syntax analysis result is unstable and affects the result of extracting evaluation collocation. To solve this problem,this paper presents an improved method of extracting evaluation collocation based on kernel sentences,which extracts evaluation collocation by combining kernel sentences and syntactic dependency. This method can significantly improve the stability of the syntax analysis result,and it also can add the analysis of the coordinative relationship among the emotional words and among the opinion targets when dealing with complex sentences. Experimental result exhibits that this method can improve the recall rate and accuracy.
