Abstract

The invention provides an automatic knowledge graph construction method based on multi-source heterogeneous power equipment data, and aims at structured data such as table data, various types of table data are transferred into an Excel table, and a data conversion rule and a data processing rule are defined, so that mapping from the structured data to a knowledge graph is completed; automatic extraction from a database to a knowledge base is performed, information extraction is performed on power text and webpage information by mainly adopting a deep learning method aiming at unstructured text data, an entity identification relation extraction process is completed, SPO triple extraction on the unstructured data is achieved, and finally integrated data is stored into Neo4j in a form of an RDF (Resource Description Framework) file. Visual display of the knowledge graph is achieved through a Neo4j graph database, and semantic query is performed by using a cypher query language.

Description

technical field [0001] The present application relates to the fields of electric power technology and knowledge map technology, and in particular to an automatic knowledge map construction method based on multi-source heterogeneous power equipment data. Background technique [0002] In the field of electric power, my country's power system has entered a period of rapid development. In order to improve the informatization level of the power grid, at the beginning of 2019, the State Grid proposed to build "three types and two networks" to raise the ubiquitous power Internet of Things to the same level as the strong smart grid. high. The ubiquitous power Internet of Things refers to the full application of modern information technologies such as mobile Internet and artificial intelligence and advanced communication technologies around all links of the power system to realize the interconnection of all things and human-computer interaction in all links of the power system, with c...
