Abstract

The invention discloses a text classification method and device, and relates to the technical field of computers. A specific embodiment of the text classification method comprises the steps of extracting sentence vectors of a to-be-classified text by using a word vector model to obtain a sentence vector set of the to-be-classified text; extracting a topic sentence vector of the to-be-classified text from the sentence vector set of the to-be-classified text; utilizing a topic sentence vector of the to-be-classified text; using a classifier model to predict the category of the to-be-classified text, the classifier model comprising a plurality of clustering center vectors, and predicting the category corresponding to the clustering center vector having the smallest distance with the topic sentence vector of the to-be-classified text as the category of the to-be-classified text. According to the embodiment, new events can be automatically classified, and the labor cost is reduced, and theclassification accuracy can be improved, and the problem that the category number is difficult to determine is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a text classification method and device. Background technique [0002] The customer service system of e-commerce is the communication window between customers and merchants. There are various ways of communication between customer service and customers, among which online communication, that is, online text communication between the customer and customer service through the Internet, is the most common way of communication. A complete online communication between the customer and the customer service is defined as an online communication event, referred to as an event. Usually, an event includes multiple rounds of textual communication between the customer and the customer service. The data generated by the customer service system has great commercial value in analyzing customer needs, understanding customer service experience, and making business decisions, and the co...
