Abstract

The invention discloses a similar user search device based on community search. The device comprises a memory and a processor; the memory stores a user search program which can run in the processor. When the program is executed by the processor, the processor realizes the following steps of constructing an undirected connected graph according to user information in a target social network platform; obtaining a query node set composed of multiple target users with an association relation, wherein the query node set is a subset of a node set in the undirected connected graph; performing iterative operation on the undirected connected graph according to the query node set and a preset community search algorithm, thereby deleting nodes on the undirected connected graph, until a spanning subgraph meeting a second preset condition is obtained after the nodes are deleted; and taking users corresponding to nodes in the spanning subgraph as similar users of the multiple target users. The invention further provides a similar user search method based on community search and a computer readable storage medium. The method and the device have the advantages that the accuracy of searching for thesimilar users is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a similar user search device, method and computer-readable storage medium. Background technique [0002] With the development of information technology, the Internet, mobile Internet, and Internet of Things can collect more and more user information, how to collect, store and analyze this information, and then discover the similarities between different users is becoming a research hotspot. [0003] At present, existing calculation methods for user similarity mainly rely on user profiles. This method has the following defects: on the one hand, it is difficult for the user profile to reflect all the characteristics of a person, and on the other hand, if the user profile is incomplete, then the calculation of the similarity is not ideal. The resulting similar users are less accurate. Contents of the invention [0004] The present invention provides a similar user sear...
