| 摘 要： | 研究并实现三种文档倾向性识别的方法：基于情感词加权的方法、基于语义模式分析的方法和基于文本分类的方法。第一种方法利用特征词汇的情感语义倾向性。第二种方法对自然语言的句法结构进行简化，以获取合适粒度的倾向性语义模式。第三种方法则直接利用传统的基于文本分类的方法。通过在网络舆情分析系统中的具体实现，探讨这三种方法各自的不足和优势。

| Abstract: | This paper investigates and implements three methods for document semantic orientation recognition: one is based on the weighted emotional words; another is based on the analysis of the semantic pattern; and the third is based on text classification. The first method is try to use semantic orientation of feature words. The second method is to simplify the structure of the natural language syntax, in order to acquire the appropriate size patterns with semantics tendency. The third method is based on the direct use of traditional text classification method. Through experiments and the application in an analysis system of net-mediated public opinions, shortages and advantages of the three methods are proposed. |
