Abstract

The invention discloses a sentiment classification method and device based on a combined feature vector and a SVM[perf] (Support Vector Machine). The method comprises the following steps: obtaining a plurality of comment texts from the Internet; carrying out word segmentation on the plurality of comment texts, and dividing each sub-component word; obtaining the morphology features of a sentence; extracting the syntax features of each comment text; through a preset algorithm, combining the morphology features with the syntax features to obtain the combined feature vector of each comment text; and according to the combined feature vector of each comment text, training a SVM[perf] model so as to regulate the operation parameter of the SVM[perf] to obtain an optimal classification result. The method uses the combined feature vector with the SVM[perf] to carry out sentiment classification on the comment texts so as to obtain the optimal classification result, classification accuracy is improved, the emotional tendency of a user in the text is better identified, and the method is simple and convenient.

Description

technical field [0001] The present invention relates to the field of computer and Internet technologies, in particular to a combination feature vector and SVM perf The Chinese emotion classification method and device of the present invention. Background technique [0002] With the continuous development of the Internet and Web 2.0, e-commerce has become an important shopping channel that is indispensable in people's daily life. On the e-commerce website, buyers can comment on the purchased items and express their opinions and satisfaction, and these comments often contain emotional factors, including the buyer's attitude. By analyzing the purchase reviews posted by users, the emotions of users can be classified. All e-commerce companies are also fully aware of the important value of this part of data information, and strive to obtain more accurate and effective data to provide data support for future decision-making. However, the transaction volume of an e-commerce platfo...
