Abstract :
Recently public, government, company and other forms of communities are extremely vocal about their opinions and perceptions on their appeals, policies and products on the micro-blog. Sentiment analysis on micro-blog data has attracted much attention for its application on opinion polarity, classification, summarization and query. However, the related state-of-the-art approaches for sentiment analysis are mainly focused on Twitter data. They don´t work well with Chinese micro-blog for word segmentation, feature word combination and feature extraction problems. In this paper, we propose to improve Chinese micro-blog sentiment analysis performance by 1) use sliding window feature combination detection and sentiment phrase dictionary combined method to address semantic recognition problems on metaphor, adversative, multiple negation and irony; 2)propose ten Chinese micro-blog features for sentiment analysis; 3)find most impactful feature combination for the sentiment classifier. Experimental results show that our semantic sentiment space model is helpful to Chinese micro-blog sentiment classification and our basic feature combination outperforms the traditional classification algorithm TD-IDF and KNN on standard measurement.
