Abstract

There are few studies on automated parsing of Chinese privacy policies, and the extracted information is not comprehensive enough which cannot meet the demand of management for automated review of Android App privacy policies. In order to realize the automated parsing of Chinese privacy policies, this paper proposed a Chinese privacy policy parsing algorithm based on dependent syntax, called PPExtractor. Based on two types of seed patterns, verb and preposition, PPExtractor used the bootstrap pattern method to generate the set of privacy event patterns. Through pattern matching, PPExtractor could effectively extract the privacy information collected and used by developers and third parties in privacy regulations, as well as the privacy information that Apps required users to input, providing a basis for management to regulate Android Apps' Illegal acts related to privacy information. This method could more comprehensively extract the privacy information collected in the Chinese privacy regulations. The experimental results show that PPExtractor can effectively identify privacy-related sentences in privacy policies and extract information related to user privacy in the sentences.
