Abstract

The invention provides an information recommendation method and device based on a knowledge graph. The information recommendation method based on the knowledge graph comprises the steps of when a search request carrying a target entity is received, generating the knowledge graph for the target entity, and the knowledge graph comprises similar entities, association relationships between the similarentities and association relationships between the target entity and the similar entities; calculating the similarity between each similar entity in the knowledge graph and the target entity; and recommending similar entities to the target entity according to the similarity from high to low. According to the scheme provided by the invention, the recommendation accuracy is effectively improved.

Description

technical field [0001] The invention relates to the field of computer technology, and in particular, to a method and device for recommending information based on a knowledge graph. Background technique [0002] Knowledge Graph (Knowledge Graph), also known as scientific knowledge graph, is called knowledge domain visualization or knowledge domain mapping map in the library and information industry. Build, map and display knowledge and the interconnections between them. However, the amount of information given by the knowledge graph is relatively large, and it is sometimes difficult for users to quickly search for the content they want from the knowledge graph. SUMMARY OF THE INVENTION [0003] The embodiments of the present invention provide an information recommendation method and device based on a knowledge graph, which effectively improves the accuracy of recommendation. [0004] An information recommendation method based on knowledge graph, comprising: [0005] When...
