| 摘 要： | 极性词典是文本情感分析和倾向性分析的基础。本文构建了一个全面、高效的极性词典,包括基础词典、领域词典、网络词词典以及修饰词词典,深入研究了修饰词对极性词的影响,将极性词与修饰词组合成极性短语作为极性计算的基本单元,提出了一种基于极性词典的情感分析方法。实验结果表明,利用本文构建的词典进行倾向性分析效果不错。

| Abstract: | A polarity lexicon is the foundation of sentiment analysis and orientation analysis.An overall and effective polarity lexicon was constructed,including base lexicon,domain lexicon,network lexicon and modifier lexicon.The influence of modifiers to polarity words was studied.A sentiment analysis method based on a polarity lexicon was proposed,in which the modifiers and polarity words were combined into polarity phrases,and the phrase was used as the basic unit to compute the polarity of sentences and texts.Experimental results showed that the effect of orientation analysis using polarity lexicon raised in this paper was good. |
