Abstract:

In this paper, we propose a new model of sentiment analysis which is based on the recursive and divided function, and explain the rationality of the model. The paper analyzes the advantages and disadvantages of sentiment analysis. The advantages of the resourcebased approach are that the emotional vocabulary is accurate. The shortcomings of this method is that the soundness is poor. But the statistical methods are opposite. Additionally, the paper provides a new way to analyse the sentiment of texts,and verifies the effectiveness. The method attains an accuracy of 77.68% on the test, although the data is imbalancing.
