Sentence semantic orientation calculation algorithm based on structure analysis

摘要

It is urgent to find an automatic method of an automatic orientation calculation on the large-scale text in Chinese. Rather than comment their orientation directly in comment texts, people may express their orientation on topic by describe its features using orientation words. The describe word on features indicated their orientation. The orientation of comments on object is called topic orientation. Although the word orientation, also called word polarity, is the foundation for the text orientation analysis, the sentence structure also should be considered in this process. In this paper, text topic orientation is calculated by not only word orientation, but also sentence structure, and an Emotion Submission algorithm is proposed to calculate the sentence topic orientation. This method is suitable for goods comments. The experiment results show that the proposed algorithm is reasonable.
