[0072] (2) Analyzing the structured data by using a preset rule model to obtain the first instance element data contained therein;

[0073] (3) Analyzing the unstructured data by using a pre-built NLP recognition model to obtain the second instance element data contained therein;

[0074] (4) Fusing the first instance element data and the second instance element data to obtain the extracted instance element data.

[0075] For example, for highly structured structured data such as name, gender, and age, you can directly use the rule model to extract the instance element data contained in it. For unstructured data, such as judicial documents in the legal field, if you want to extract a certain type of dispute focus from all judicial documents under a certain case, you need to manually label the data, train the NLP model, and then optimize iteratively to reach a certain target. After that, it is parsed to extract the instance feature data contained in the unstructured data.

Abstract

The invention is applicable to the technical field of computers, and provides a knowledge graph creation method and device, a storage medium and a server. The knowledge graph creation method comprisesthe steps of obtaining a material text of a knowledge field to which a to-be-created knowledge graph belongs; analyzing the material text according to a pre-constructed graph knowledge layer schema,and extracting instance element data; performing data fusion on the extracted instance element data and the graph knowledge layer schema to obtain a first knowledge graph in the vertical field; searching for other knowledge graphs having at least one associated graph node with the first knowledge graph from a preset knowledge graph library; and transversely fusing the first knowledge graph and theother knowledge graphs by taking the associated graph nodes as connection points to obtain a created knowledge graph. By adopting the knowledge graph creation method provided by the invention, the knowledge graph creation efficiency can be improved.

Description

technical field [0001] The present application belongs to the field of computer technology, and in particular relates to a method, device, storage medium and server for creating a knowledge map. Background technique [0002] At present, the creation process of the knowledge map mainly includes: business personnel sort out the knowledge framework, nodes, relationships, and triples in the vertical field in Excel, and output the knowledge layer schema in Excel format; hand over the knowledge layer schema in Excel format to the modeler , the code is written by the modeler and stored in the graph database; the data is processed and cleaned offline according to the knowledge layer schema, and the unstructured and semi-structured data are processed into structured data corresponding to the knowledge layer schema; the modeler writes The code fuses the knowledge layer schema with structured data to generate a complete knowledge map. The above process involves a lot of manual operati...
