Abstract

The present application discloses a text classification feature extraction method, which obtains a feature word set from multiple training texts in a training set, and determines the attribute correlation between each feature word in the feature word set and a certain category and the attribute correlation of each feature word in the feature word set. For the word frequencies in this category, the feature words whose attribute relevancy meets the preset first condition and the feature words whose word frequencies meet the preset second condition are selected from the feature word set as the classification feature words of the corresponding category. The present application also proposes 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, device, 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, and a large number of texts provide convenience to users, but also bring great inconvenience to users' search. How to effectively manage these texts is a current hot issue. Faced with this problem, text classification has been proposed. Text classification can determine a category for the text according to the pre-defined subject categories, 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. SUMMARY OF THE INVENTION [0003] An example of this application provides a text classification feature extraction...
