Abstract

The invention discloses a method and device for determining an association relationship between entities, and equipment and a storage medium, and is applied to the technical field of natural languageprocessing, knowledge maps and deep learning. According to the specific implementation scheme, the method comprises the steps of obtaining target association information, wherein the target association information comprises a first word representing a first entity, a second word representing a second entity and a third word representing a target association relationship; determining a first semantic feature according to the target association relationship and similar text segments for the target association information in a preset text segment library; determining a description text for the target associated information according to the target associated information and a preset knowledge graph; determining a second semantic feature according to the target associated information and the description text; and according to the first semantic feature and the second semantic feature, determining a confidence coefficient of a target association relationship between the first entity and thesecond entity.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, specifically to the technical fields of natural language processing, knowledge graph and deep learning, and more specifically to a method, device, device and storage medium for determining the relationship between entities. Background technique [0002] With the development of artificial intelligence technology, the electronic management of information is gradually emerging. In various fields, in order to improve the efficiency of information acquisition, when managing information electronically, it is possible to carry out related management of related information. Wherein, the association relationship between information can be determined through the association relationship between entities described by the information. [0003] In related technologies, when performing information association management, a natural language processing method is often used to recall tw...
