Method and device for identifying target user of service provider

Abstract

The embodiment of the invention provides a method and device for identifying a target user of a service provider, and the method comprises the steps: obtaining a knowledge graph which comprises a plurality of nodes, wherein each node represents one entity and corresponds to one entity vector; and in the plurality of nodes, connecting the nodes with the association relationship through connecting edges, wherein each connecting edge corresponds to one association vector; for the first node of any first type of service party in the knowledge graph, when a target user is identified, determining asecond node of the second type of service party and a third node of the target user of the second type of service party in the knowledge graph; determining a reference entity vector based on the entity vector of the first node and the association vector of the connection edge of the second node and the third node; calculating distance between the reference entity vector and an entity vector of a node of each person user;. based on the distance, selecting a target node, and taking a personal user represented by the target node as a target user of the first type of service provider.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer technology, and in particular to a method and device for identifying a target user of a server. Background technique [0002] In the Internet field, in order to implement risk control, it is usually necessary to identify the user's identity. The users here can include two categories: individual users and unit users (also called service parties). For an individual user, the identity of the user is usually identified based on the user's description information, such as age, salary, and occupation. As for the service provider, the identification of the service provider is realized by identifying the identity of the target user. The target users here may include, but are not limited to, the ultimate beneficiary, etc. Among them, the ultimate beneficiary refers to the natural person who ultimately controls the unit directly or indirectly. [0003] In traditional technology, th...

Problems solved by technology

[0003] In traditional technology, the method of equity penetration is generally used to mine the target users of the service provider. However, due to the fact that there may be incomplete unit holding data, this makes it impossible to identify the target users of the service provider based on traditional methods.
