Abstract

Embodiments of this specification provide a structured data classification method, apparatus, device, and medium. The method includes: performing a sampling operation on one or more tables stored in a structured database, so as to obtain a field set corresponding to the table; obtaining field information corresponding to each field in the field set, and using a preconfigured scoring rule Or the scoring model performs a scoring operation on the field information to obtain a scoring result corresponding to the field; wherein, the scoring result can vaguely represent the category of the field; according to the scoring result corresponding to the field, a predetermined deep learning model Perform training to obtain a trained deep learning model; use the trained deep learning model to predict fields of structured data of unknown categories, and determine a category corresponding to the structured data according to the prediction results.

Description

technical field [0001] This specification relates to the technical field of data processing, and in particular, to a structured data classification method, apparatus, device, and medium. Background technique [0002] With the wide application of the Internet and big data technology, network data security has been highly valued by governments at all levels, enterprises and institutions, especially with the country's increasing emphasis on user privacy protection, various laws and regulations on data security and privacy protection have been introduced . Internet companies will collect various user data in the normal business process, such as collecting personal privacy data such as mobile phone numbers, ID numbers, bank card numbers, etc. with the authorization of users. When protecting the security and privacy of user data, it is necessary to classify and grade the user data saved by the enterprise, and then further protect the data of different security levels in accordanc...
