面向电影评论的情感词典构建方法研究

Research on the Construction Method of Emotion Lexicon for Movie Review

在对中文网络文本进行情感分析时,情感词典的完备性以及好坏对情感分析的效果有着至关重要的影响。虽然已经有了几个通用的中文情感词典,但是现实生活中电影领域有自身特有的领域词汇、领域词语的特殊使用方式等,现有的几个情感词典若用在电影评论的情感分析中使用,往往效果不佳。现今还没有学者发布行业认可的、官方的可用于分析电影评论的领域情感词典。因此,论文的重点工作是自主构建一个电影领域情感词典,并用其完成电影评论的情感分析任务。

The completeness and quality of the emotional lexicon have a crucial influence on the effect of the emotional analysis on the Chinese network text.Although there are several general Chinese emotion dictionaries,in real life,the movie field has its own unique domain vocabulary,the special use of domain words,and so on.There is no industry-approved,official domain sentiment lexicon that can be used to analyze movie reviews.Therefore,the focus of this paper is to construct a movie domain emotion lexicon and use it to complete the task of emotion analysis of movie reviews.
