摘要 针对中文的语料,采用基于条件随机场的方法,在词、词性特征的基础上结合最近名词、句法依赖关系和句子倾向性等特征,分析不同特征对于评价对象抽取的影响.实验结果表明,结合了词、句子倾向性、词性、语法依赖关系、邻近名词等特征的条件随机场方法对于中文句子评价对象的抽取更有效. In this paper we adopt CRFs and focus on analyzing the effectiveness of features used in ex tracting sentiment objects from Chinese sentences such as token, part of speech ( pos), senti ment of sentence, grammar dependence and so on. Results of experiment has shown that the features of token, pos, sentiment of sentence and grammar dependence and so on are effective when using con ditional random fields to extract the sentiment obiects.
