Method for automatically extracting privacy policy of application software

The invention provides an automatic privacy policy extraction method for application software, and relates to the technical field of Android application, the method comprises the following steps: statically extracting network address links in an application software code file to obtain a first network address set; dynamically extracting associated network address links in the application software test running period to obtain a second network address set; obtaining a union set of the first network address set and the second network address set to obtain a target network address set; and traversing and extracting the text content in each network address in the target network address set, and detecting the text content of which the type is the privacy policy in the target network address set based on the trained text classification model. According to the invention, the extraction efficiency of the network address can be improved, the situation of missing extraction of the network address link is avoided, and t
