Abstract

The embodiment of the invention discloses a user identity recognition method and device, and relates to the field of knowledge graph data processing. The method comprises the steps that graph embeddedprocessing is conducted on nodes in knowledge graph data, and obtaining low-dimensional representation vectors of the nodes; extracting node data from the knowledge graph data through a pre-trained extraction model to form a node matrix; calculating and combining the low-dimensional representation vector with the node matrix to generate node sequence data; and inputting the node sequence data into a pre-trained judgment model, and outputting a user identity recognition result.

Description

technical field [0001] The present disclosure relates to the field of knowledge graph data processing, and in particular to a user identity identification method and device. Background technique [0002] The field of financial big data is a relatively mature field of artificial intelligence technology application. In the field of financial credit, the use of knowledge graphs to identify identities and then carry out anti-fraud identification has been widely used in actual business. [0003] In the existing technology, such as figure 1 As shown, a typical anti-fraud system based on knowledge graph is shown. Combined with graph database, relational data query is performed on the input items, variable calculation is performed, and the calculation results are input into the fraud model; the output of the fraud model is The fraud results are input into the anti-fraud and risk control system for subsequent data statistics and analysis. Depend on figure 1 It can be clearly concl...
