Abstract

The invention discloses a text classification feature extraction method. According to the method, a feature word set is acquired from multiple training texts in a training set, the property correlation between each feature word in the feature word set and a certain category and the word frequency of each feature word in the category are determined, and the feature word with the property correlation meeting a first preset condition and the feature word with the word frequency meeting a second preset condition are selected from the feature word set to serve as classification feature words of the corresponding category. The invention furthermore provides a corresponding text classification method, a text classification feature extraction device and a text classification device.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular to a text classification feature extraction method and device, and a text classification method and device. Background technique [0002] At present, with the development of Internet technology, there are more and more texts on the Internet. While providing convenience to users, a large number of texts also bring great inconvenience to users' search. How to effectively manage these texts is a current hot issue. In the face of this problem, text classification is proposed. Text classification can determine a category for the text according to the pre-defined topic category, and classify the text according to the category, so as to facilitate users. find. As a key technology for managing massive data, text classification has been widely used. Contents of the invention [0003] The application example provides a method for extracting text classification...
