Research on building Chinese basic semantic lexicon

词语的情感倾向判别是文章语义情感倾向研究的基础工作。利用中文情感词建立一个基础情感词典,为专一领域情感词识别提供一个核心子集,能够有效地在语料库中识别及扩展情感词集,并提高分类效果。在中文词语相似度计算方法的基础上,提出了一种中文情感词语的情感权值的计算方法,并以HOWNET情感词语集为基准,构建了中文基础情感词典。利用该词典结合TF-IDF特征权值计算方法,对中文文本情感倾向进行判别,实验结果表明,该方法取得了不错的分类效果。

Judging the emotional tendencies of Chinese words is the basic work of the semantic emotional tendency study of text. Building a basic emotional lexicon with Chinese emotional words will provide a core subset for identifying emotional words in a special area. It is able to identify and enlarge emotional word set effectively in corpus and also improve the efficiency of classification. A method of calculating the emotional value of Chinese emotional words on the basis of the similarity of Chinese words was provided.
