Abstract
As a result of the rapidly increasing number of microblog users, sentiment analysis on mi-croblog data has attracted more and more attention. The first step of sentiment analysis is to effectively identify the subjective information of the texts. How to effectively extract subjective information and analyze opinions on microblog has become a new popular research topic. In this paper, we use Naive Bayes classifier to give a solution for the classification between subjective and objective sentence in Chinese microblog. First, we present the difference between microblog and other texts, and then we select some subjective and objective lexical clues for Chinese microblog. Second, we introduce 2-POS model and its feature selection methods. Third, we take key words and subjective lexical clues as semantic features, 2-POS as grammatical features, and then use them to construct Naive Bayes classifier respectively. The experiment results show that the method that uses both the semantic features and the grammatical features achieves the best performance.关键词
