Abstract

The invention provides an automatic classification method based on Chinese privacy policy terms, which belongs to the technical field of natural language processing, and comprises the following steps:data processing: obtaining privacy policies of a plurality of applications as a data set, manually labeling to obtain a data set with labels, and then cleaning the data set to obtain a training sample data set; data training: performing feature selection on the training sample data set, selecting effective features capable of identifying different clause categories, and establishing a detection model; and judging whether the privacy policy text has integrity or not. According to the automatic classification method based on the Chinese privacy policy terms, through automatic classification based on the privacy policy terms, the privacy policy content is quickly classified to each classification category attribute, so that a user can read and understand conveniently, and integrity detectionof the privacy policy terms is realized; and the user can quickly identify whether the privacy policy is complete or not.

Description

technical field [0001] The invention belongs to the technical field of natural language processing, and more specifically relates to an automatic classification method based on Chinese privacy policy clauses. Background technique [0002] Nowadays, with the increasing number of APP users, user privacy data leakage incidents emerge in an endless stream. The APP privacy policy is a statement disclosing how user data is collected, used, shared and managed, and it is a self-discipline measure for APP operators to collect user information. However, because the privacy policy is long, difficult to understand, and takes a long time to read, most users agree to the privacy policy without reading it. Therefore, the problems in the privacy policy are likely to become loopholes in user privacy security. In response to the above phenomena, in order to help users read the Chinese privacy policy and reflect the quality of the privacy policy, it is necessary to automatically classify the ...
