Example Embodiment

[0059] In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application.

[0060] To facilitate understanding, the terms involved in the embodiments of this application are explained below:

[0061] Graph database: It is a type of NoSQL database that uses graph theory to store the relationship information between entities. Graph database is a non-relational database, which uses graph theory to store the relational information between entities. Common graph databases include Neo4j, FlockDB, AllegroGrap, GraphDB, InfiniteGraph, etc.

[0062] Knowledge Graph: Known as knowledge domain visualization or knowledge domain mapping map in the library and information industry, it is a series of various graphs showing the relationship b...

Abstract

The invention discloses a knowledge graph construction method and device, electronic equipment and a storage medium. The difficulty of creating the knowledge graph is reduced; the method comprises thesteps that tables corresponding to at least two entity categories respectively are obtained, each table comprises a name column and at least one relation column, the name column comprises entity names of entities belonging to the corresponding entity categories, and each relation column comprises the incidence relation between entities in the table and entities in any other table; according to the entity names extracted from the name columns of the tables, first statements corresponding to the entity names are generated respectively, and each first statement is used for adding entity nodes corresponding to the entity names into a graphic database; according to the association relationships extracted from the relationship columns of the tables, second statements corresponding to the association relationships are generated respectively, and each second statement is used for adding an edge representing the association relationship between the entity nodes; and calling a graphic databaseto analyze the generated first statement and second statement to obtain a knowledge graph.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a knowledge map construction method, device, electronic equipment and storage medium. Background technique [0002] The construction of a knowledge map usually involves a relatively complicated process: first, professionals process the data to be processed into a data form that meets the import requirements of the graph database according to the requirements of the graph database; The data to be processed required by the import is imported into the graph database, and the corresponding knowledge map is generated by the graph database. However, it is extremely error-prone in the process of manual data processing, the data maintenance is difficult, and users need to learn how to use the graph database, so the threshold for use is very high. Contents of the invention [0003] Embodiments of the present application provide a knowledge map construction method, devic...
