Example Embodiment

[0030] In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described below through specific embodiments and accompanying drawings.

[0031] The present invention is a sentiment tendency detection method (or called sentiment tendency analysis method) oriented to comment data, which is used for mining user opinions in comments. The present invention first obtains online review data from major mainstream review websites by focusing on the crawler. Then, for large-scale reviews, the semantic dictionary and sentence pattern library are organized in a semi-automatic way. Finally, for each sentence in the review, perform word segmentation and other processing and analysis, on this basis, extract keywords or key sentence patterns as features, and use the maximum entropy classifier to achieve sentiment tendency detection and sentiment classification. figure 1 It is a flow chart of the steps...

Abstract

The invention relates to an emotion tendency detection method for comment data. The method comprises the steps of 1) acquiring comment data and performing standardization treatment on the same; 2) performing word segmentation treatment on sentences of the comment data subjected to the standardization treatment; 3) performing factor analysis on the sentences subjected to word segmentation and identifying various kinds of words having influence on emotion tendency detection analysis; 4) performing sentence pattern template matching on the comment data subjected to the factor analysis according to a sentence pattern template library; 5) determining antecedents corresponding to reference words in the sentences of the comment data and restoring omitted subjects; 6) regarding sentences containing evaluation object words, evaluation attribute words or emotion words as candidate emotion sentences, and identifying the sentence polarities of the candidate emotion sentences by using the maximum entropy model to obtain the emotion tendencies of the sentences. The method is based on the characteristics of diversification and orality of comment texts and improves the efficiency and the accuracy of comment data emotion tendency detection.
