Complex tail entity link splitting method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a complex tail entity splitting and linking method and device. The method comprises: determining a complex tail relationship and a complex tail entity in a complex tail triple; and inputting the complex tail relationship and the complex tail entity into the entity splitting link model to obtain link results of a plurality of simple entities output by the entity splitting link model, wherein the entity splitting link model is used for splitting the complex tail entity into a plurality of simple entities, and respectively linking the plurality of simple entities based on the corresponding label set of the complex tail relationship in the knowledge graph. According to the complex tail entity link splitting method and device provided in the embodiment of the invention, the complex tail entity is split into the plurality of simple entities, and the plurality of simple entities are respectively linked based on the tag set corresponding to the complextail relationship in the knowledge graph, so that the splitting of the complex tail entity is realized, the semantic information of the simple entities is expanded, and the link accuracy of the simpleentities is improved.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a complex tail entity splitting and linking method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of artificial intelligence technology, knowledge graph, as one of the key technologies in the development and application of artificial intelligence technology, is widely used in intelligent search, intelligent question answering, personalized recommendation and other fields. The knowledge graph organizes knowledge into triples to describe entities and the relationship between entities in the real world. However, there are a large number of complex tail triples in existing general knowledge graphs, that is, tail entities in triples are composed of multiple simple entities, and none of these simple entities are linked into the knowledge graph. Therefore, it is necessary to split the complex tail entity, a...
