Embodiment Construction

[0045] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below in conjunction with examples and accompanying drawings, but this does not constitute a limitation to the present invention.

[0046] figure 1 It is a flowchart of a method for constructing domain knowledge graph based on semantic triangle as an example of implementation of the present invention. refer to figure 1 Content, a method for constructing a domain knowledge map proposed by the implementation example of the present invention specifically includes the following steps:

[0047] S1: Extract data dictionaries, data planning and data operation scripts from domain-related relational databases, and obtain the concept of semantic triangle and the relationship between concepts. Among them, the field-related relational database refers to the relational database of the business support system in the professional field, su...

Abstract

The present invention discloses a domain knowledge map generation method and apparatus based on a semantic triangle. The method comprises: generating entities, concepts and representation representingterms and concepts in the semantic triangle in a knowledge map of the target domain; according to the preset relationship type classification rule, carrying out rule matching on the data planning ofthe application system relational database of the target domain, and establishing the relationship between the concepts; according to the concepts and the relationship between the concepts, using a graph model to establish a concept layer of the knowledge map; according the concept matched with the field including the entities in the knowledge map, establishing the concept instantiation of the entities; according to the concept layer of the knowledge map, deriving the concept layer to the relationship establishment between entities, and obtaining the relationship between entities; and according to the relationship between entities, establishing the entity layer of the knowledge map. According to the technical scheme of the present invention, concepts are separated from entities to addressthe professional needs of knowledge in a particular domain.

Description

technical field [0001] The invention belongs to the field of artificial intelligence, and in particular relates to a method and device for generating domain knowledge graphs based on semantic triangles. Background technique [0002] Financial auditing is a very professional financial supervision activity. The knowledge generated in this field is inseparable from information and data reflecting financial phenomena, which is very different from general common sense and knowledge reflecting social and natural phenomena. On the one hand, the knowledge needs of auditors are very dependent on the field, and there are many terms in the field, so the generalized knowledge base and knowledge graph cannot meet the long-tail needs of professional auditors; on the other hand, the financial audit work It is very dependent on expert experience. The summary of current audit knowledge requires the labor input of a large number of mixed talents. Audit evidence collection and audit conclusion...
