Abstract

The invention discloses a similar user search device based on community search, which includes a memory and a processor. The memory stores a user search program that can run on the processor. When the program is executed by the processor, the following steps are realized: The user information in the network platform constructs an undirected connected graph, wherein; a query node set composed of multiple target users with associated relationships is obtained, and the query node set is a subset of the node set in the undirected connected graph; according to the query node set Perform iterative operations on the undirected connected graph with the preset community search algorithm to delete the nodes on the undirected connected graph until the generated subgraph that meets the second preset condition is obtained after the node is deleted; the nodes in the subgraph will be generated The corresponding user acts as a similar user of multiple target users. The invention also proposes a method for finding similar users based on community search and a computer-readable storage medium. The invention improves the accuracy of finding similar users.

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...
