It adopts labeling word characteristic, enacting sentence sentiment orientation estimation rules for several representative sentences. Experimental result proves these rules make the discrimination for sentence more comprehensive and objective.

摘要： 针对中文句子情感倾向性判断问题，提出一种五元表示模型，给出句子级文本情感倾向性判断的定义及其主要任务，通过标注词性、制定句子情感倾向性判断规则，对具有代表性的特定句型进行分析。实验结果表明，与常用的支持向量机方法相比，该方法能够使句子情感倾向性判断更全面客观。
