Abstract

The invention provides an intelligence data fusion method and device, a Smart rule is trained and generated by adopting a decision tree ID3 algorithm, and fusion of network intelligence data is realized by performing entity extraction, entity classification, attribute recognition and attribute extraction on original network intelligence data and automatically selecting a fusion rule. The invention mainly aims to solve the problems of low efficiency and uneven fusion effect of the existing information data fusion, realize the efficient, rapid and standardized fusion of the network information data, and reduce the dependency of the network information data fusion on the knowledge of field experts.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an intelligence data fusion method and device. Background technique [0002] Intelligence data fusion is mainly to process the new intelligence data, and realize the storage of entities and attribute values ​​of the new intelligence data. Intelligence data fusion is to carry out operations such as entity fusion and attribute fusion on intelligence data, and integrate entities and attribute values ​​into the existing intelligence database by adding or updating them. [0003] At present, the method for intelligence data fusion mainly uses program scripts to verify entities and attribute values, manually extracts entities and attribute values, and combines domain expert knowledge with background or foreground visual operations to manually save network intelligence data to intelligence library. This method requires manual intervention to write new data, and the verificatio...
