Abstract

The invention discloses a knowledge graph construction method and device, and a computer readable storage medium. The knowledge graph construction method comprises the following steps: constructing an initial structured knowledge graph according to a structured database, and extracting a reference entity and a reference relationship in an unstructured text of a target field according to a standard entity and a standard relationship of the initial structured knowledge graph; and performing knowledge fusion on the reference entity and the reference relationship extracted from the unstructured text and the standard entity and the standard relationship in the initial structured knowledge graph to construct a knowledge graph of the target domain. The initial structured knowledge graph constructed by the structured knowledge is a high-quality and high-accuracy knowledge graph, and the initial structured knowledge graph is subjected to targeted expansion and completion by the aid of the unstructured text, so that a complete and high-quality target domain knowledge graph can be constructed.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a method for constructing a knowledge graph, a device for constructing a knowledge graph, a computer-readable storage medium, and an electronic device. Background technique [0002] Knowledge graph is an important cornerstone of artificial intelligence. It stores the knowledge system, concept and content of human society in the form of basic triples of "entity-relationship-entity" in the computer to form a semantic network, realizing the realization of human knowledge. The mapping between the data processed by the computer, and the knowledge graph also has the capabilities of knowledge association, knowledge reasoning, and knowledge learning, helping computers understand human language more accurately. [0003] Since the concept of knowledge graph was put forward, it has always been a hot topic of research in academia and industry. At this stage, knowledg...
