Abstract

The present application provides a method and device for determining an entity category in a knowledge graph. The scheme acquires a set of candidate data pairs, wherein the set of candidate data pairs includes at least one candidate data pair, and each of the candidate data pairs includes at least An entity and at least one category; based on the attribute information of the entity, the attribute value of the entity and / or the attribute information of the category, it is judged whether at least one entity contained in the at least one candidate data pair belongs to at least one of the candidate data pairs. category, and if so, marking the at least one category as the category of the at least one entity. In this way, the classification of entities is determined, the number of classifications of entities is expanded and / or the accuracy of classification of entities is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular, to a method and device for determining an entity category in a knowledge map. Background technique [0002] As a structured information network, the knowledge graph breaks the limitations of the original relational database, has powerful expressive ability, and plays an important role in the fields of information retrieval and information integration. Among them, classifying entities can clarify the category to which entities belong, improve the network topology structure of knowledge graphs, and improve the expressive ability of knowledge graphs. significance and value. [0003] However, in the existing technology, no matter whether manual labeling or automatic labeling is used, the classification granularity of entities is relatively rough and the accuracy is poor, which makes the knowledge coverage of the constructed knowledge map poor and limits the applicati...
