Abstract

The embodiment of the invention discloses a knowledge graph construction method and device, equipment and a medium. The method comprises the steps of obtaining a text corpus of at least one information object; extracting phrases from the text corpus; from the extracted phrases, identifying content phrases of an attention theme, an object entity, an object side surface and an action event, and identifying an association relationship between the phrases; and updating the content phrases to point elements of the knowledge graph, and updating the association relationship to edge elements of the knowledge graph. According to the technical scheme of the embodiment of the invention, the information object text corpus is extracted, the knowledge graph of the information object is constructed, a plurality of point elements and corresponding side elements such as attention topics, action events and object side surfaces are added, information extension of existing object entities in the knowledgegraph is realized, and new object entities are continuously mined from the information object to continuously expand and supplement the composition of the knowledge graph.

Description

technical field

[0001] The embodiments of the present application relate to data processing technology, in particular to natural language processing technology, and in particular to a method, device, device and medium for constructing a knowledge graph. Background technique

[0002] In the existing natural language processing (NLP) technology, in order to facilitate the identification of semantic knowledge, a database of knowledge graphs is gradually constructed. The knowledge graph includes point elements and edge elements. Point elements are used to record entities, and edge elements are used to record the relationship between entities. Entities are usually specific things in the real world.

[0003] However, when the knowledge graph is used to identify information beyond text, such as pictures, audio, and video, it is difficult to meet the information identification requirements because the above information covers the complexity of entities. Contents of the invention ...
