A method, device and equipment for identifying overlapping relationships of network security entities

Abstract

The embodiment of the present application discloses a method, device and equipment for identifying the overlapping relationship of network security entities. By obtaining the text data to be identified and inputting the text data to be identified into the target joint extraction model, the output of the target joint extraction model can be obtained. The network security entity vocabulary in the text data to be identified and the entity relationship between the network security entity vocabulary, and then determine the target network security entity included in the text data to be identified and the entity relationship between the network security entity vocabulary. The target joint extraction model can realize the parameter and structure sharing in the process of network security entity recognition and relationship extraction, and enhance the correlation between network security entity recognition and entity relationship extraction. It reduces the error transfer of entity recognition, improves the accuracy of network security entity recognition and entity relationship extraction, and realizes the extraction of overlapping relationships between network security entities.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to a method, device and equipment for identifying overlapping relationships of network security entities. Background technique [0002] In the existing network environment, there are many factors that threaten network security. Accurately discovering network security entities and their relationships from network information can effectively analyze the status quo of current security issues and the development trend of future security issues, and make corresponding security decisions accordingly. [0003] In network texts, there are some words and phrases related to network security threats, and such words and phrases are called network security entities. By performing network security entity recognition on related texts, the network security entities contained in the text can be obtained. In addition, specific relationships may exist between network security enti...

AI Technical Summary

Problems solved by technology

[0004] At present, the accuracy of network security entity identification and entity relationship extraction in network information text is not high, and the "one-to-many" overlapping relationship between network security entities in network information text cannot be completely extracted. As a result, network security threat information cannot be obtained timely and accurately from network information, which restricts network security situation analysis and early warning capabilities
