基于知网的模糊情感本体的构建研究

摘要

构建模糊情感本体是在线评论情感分析的基础.针对在线评论情感表达的多样性和模糊性,将情感本体划分为评价词本体和情感词本体,利用模糊理论和知网相关概念,构建模糊情感本体的基本模型.根据评价词和情感词的各自特点,运用模糊化处理和语义相似度的相关理论,分别对评价词模糊本体和情感词模糊本体的情感类型和隶属度进行了相应处理.并通过与点互信息方法比较,验证了情感本体模型在自动获取情感类方面的有效性,最后进行了相关数据统计.%Considering the diversity and ambiguity of emotional expression in Chinese on-line reviews, this study uses fuzzy theory and ontology concept to build the basic model of fuzzy emotion ontology based on HowNet. Based on each features of the evaluation words and emotional words, using the relevant theories of fuzzy processing and semantic similarity, respectively processing the emotion classes and membership of the fuzzy ontology of evaluation words and emotional words, and by comparison experiment, our fuzzy emotion ontology outperform Pointwise Mutual Information in the aspect of getting emotion classes automatically.
