Related entity determination method and device and computing equipment

Abstract

An embodiment of the invention provides a related entity determination method and device and computing equipment. The method includes: acquiring a target knowledge graph which at least comprises a target entity; determining a candidate entity set, in the target knowledge graph, of the target entity, wherein the candidate entity set includes candidate entities corresponding to reachable sides of the target entity; determining target entity related entities according to the candidate entity set. By the related entity determination method and device and the computing equipment, the recall rate ofrelated entity determination results can be increased.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method, device and computing equipment for determining related entities. Background technique [0002] Related entities can be considered as other entities that co-occur with the queried target entity in the same query, which is of great significance for users to obtain relevant information about the queried target entity; for example, after the user enters a query statement, the search engine will not only search In addition to displaying the target entity (such as a web page link) corresponding to the query statement to the user, it will also recommend related entities that co-occur with the target entity during the query process to the user to guide the user to search again and improve the user's access to relevant information convenience; a typical scenario is that after the search engine searches for the target entity corresponding to the query statement, i...

Problems solved by technology

[0003] The inventors of the present invention have found that at present, statistics of other entities co-occurring with a target entity are mainly performed through open texts (such as news texts) to determine the related entities of a target entity; however, the content of open text entry has certain limitations and timeliness, which makes the determination results of related entities through open text statistics uncontrollable, resulting in a low recall rate of related entity determination results (recall rate indicates the ratio of the number of related entities determined to the total number of related entities, which is a comprehensive measure of the determination results a manifestation of sex)
