摘　　要：【目的】从社交媒体用户生成内容中发现未知情感词,构造领域情感词典,应用于汽车评论的情感分析。【方法】选取HowNet情感词典作为种子,以实际汽车评论作为语料,分别利用PMI和Word2Vec算法识别新词情感极性,根据集成规则对二者识别结果综合判定,通过情感分类实验对比显示本文算法的有效性。【结果】按照该方法构造的情感词典准确率比How Net情感词典提高21.6%,较分别使用PMI和Word2Vec算法构建的词典分别提升3.7%和2.1%,同时正面、负面情感词数量均有大幅增加。【局限】语料来源单一,应用于其他领域具有一定局限性。【结论】该方法构造的情感词典可有效应用于社交媒体文本情感分析。[Objective] This study aims to construct a domain sentiment lexicon by discovering unrecognized sentiment words from user-generated contents on Chinese social media to apply it to automotive comments sentiment analysis.[Methods] First,words in HowNet are selected as the seeds,and PMI and Word2Vec algorithm are used to calculate the sentiment polarity of the candidates respectively on real automative corpus.Then the results of the two discriminations are judged synthetically according to the ensemble rules.Finally the proposed method was shown effective by the comparison of the sentiment classification experiments.[Results] The accuracy rate of the lexicon constructed according to proposed method is 21.6% higher than that of HowNet.The lexicon constructed by PMI and Word2 Vec respectively increase 3.7% and 2.1%.Meanwhile the number of positive and negative emotional words are greatly increased.[Limitations] The source of corpus is single,and it has certain limitations in guiding other fields.[Conclusions] The sentiment lexicon constructed by this method can be applied to sentiment analysis of social media texts effectively.
