Abstract

The invention relates to the technical field of computer natural language processing, and discloses an entity relationship extraction method and device for an open domain and terminal equipment. The method comprises the steps of obtaining to-be-processed open domain data; inputting the open domain data into a trained entity relationship extraction model to obtain an entity relationship in the opendomain data; wherein the entity relationship extraction model is trained by adopting a supervised learning algorithm. According to the invention, the accuracy of an open domain-oriented entity relationship extraction result can be improved.

Description

technical field [0001] The invention relates to the technical field of computer natural language processing, in particular to an open domain-oriented entity relationship extraction method, device and terminal equipment. Background technique [0002] The purpose of relational extraction is to extract the semantic relationship of entities from a large number of unstructured texts that exist on the Internet, and use them to build knowledge graphs or provide people with more efficient information acquisition tools. Relationship extraction usually uses triples as a basic data unit, in the form of <subject, predicate, object>, where subject is the head entity, object is the tail entity, and predicate is the relationship between the two entities. Usually the head entity refers to a specific person or thing, and the tail entity can refer to some attributes besides a specific person or thing. [0003] At present, the commonly used entity relationship extraction methods can be ...
