Abstract

The invention provides an emotion recognition method and an emotion recognition device for customer consultation texts and belongs to the technical field of date service. The emotion recognition method for customer consultation texts comprises choosing characteristics of a customer consultation text training set to form a characteristic set which comprises a flagged text having being flagged emotion category; converting the flagged text into a characteristic vector represented in the characteristic set to obtain a training data set; training the training data set to generate a support vector machine (SVM) classifier; and inputting the to-be-analyzed customer consultation texts into the SVM classifier to be analyzed to obtain emotion categories represented by the customer consultation texts. The emotion recognition method can improve emotion classification accuracy.
