Problems solved by technology

[0005] However, the disadvantage of using Bootstrapping for relationship extraction is mainly the lack of generalization of the template, which does not work well on text with complex contexts, and cannot obtain perfect and correct relationships between entities.

Embodiment Construction

[0049] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0050] Artificial Intelligence (AI for short) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is a comprehensive technique of computer science that attempts to understand the nature of intelligence and produce a new kind of intelligent machine that can respond in a similar way to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines, so that the machines have the functions of perception, reason...

Abstract

The invention discloses a relation extraction method and device, equipment and a storage medium, and relates to the technical fields of artificial intelligence, intelligent transportation and the like. The method comprises the following steps: acquiring a target text containing a first entity and a second entity; labeling the first entity, the second entity and the keyword in the target text to obtain a labeled target text; performing coding processing on the target text with the label to obtain a coding representation vector and an entity keyword representation vector corresponding to the first entity, and a coding representation vector and an entity keyword representation vector corresponding to the second entity; and determining the relationship between the first entity and the second entity according to the code representation vector and the entity keyword representation vector corresponding to the first entity and the code representation vector and the entity keyword representation vector corresponding to the second entity. The invention provides a relation extraction scheme with higher generalization, so that improvement of the perfection and accuracy of a relation extraction result is facilitated.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202111037638.9 and the title of the invention "relationship extraction method, device, equipment and storage medium" submitted on September 06, 2021, the entire content of which is incorporated by reference in this application . technical field [0002] The embodiments of the present application relate to technical fields such as artificial intelligence and intelligent transportation, and in particular to a relation extraction method, device, device, and storage medium. Background technique [0003] Relation extraction refers to obtaining the relationship between entities contained in the text. For example, taking character relationship extraction as an example, two character names are identified from the text, and then based on the information contained in the text, the character relationship between the two character names, such as children and spouses, is determined. ...
