Embodiment 1

[0035] The embodiment of this application proposes a power knowledge map construction method based on the full service data of the power grid, such as figure 1 As shown, the power knowledge map construction method includes:

[0036] Step 1. Convert the full service data of the power grid into an RDF model;

[0037] Step 2, classify the data in the RDF model, and select phrases with similar meanings based on the divided data;

[0038] Step 3, the selected phrases are constructed into knowledge triplets according to different entity attributes;

[0039] Step 4: Construct the power knowledge map according to the triplet.

[0040] In implementation, the full-service unified data center is a platform for modeling, collecting, unified storage management and analysis and application of structured data, measurement and collection data and unstructured data of the power grid. The main technical structures are as follows: figure 1 shown. The data layer is the data of each business s...

Abstract

The embodiment of the invention provides an electric power knowledge graph construction method based on power grid full-service data. The electric power knowledge graph construction method comprises the steps of converting the power grid full-service data into an RDF model; performing type division on data in the RDF model, and selecting phrases with similar meanings based on the divided data; constructing knowledge triples for the selected phrases according to different entity attributes; and constructing an electric power knowledge graph according to the triple. By means of the knowledge graph technology, cross-service communication of service data is achieved, and gridding high-speed retrieval and deep mining functions are provided, and the normalization, standardization and lean levelof enterprise management is improved.

Description

technical field [0001] The invention belongs to the field of database management, and in particular relates to a method for constructing a power knowledge map based on power grid full-service data. Background technique [0002] The full-service unified data center is the collection center of full-service, full-type, and full-time dimension data. It provides complete data resources, efficient analysis and computing capabilities, and a unified operating environment for the company's various analysis and decision-making applications, changing the past analysis. Applying the situation of repeated data extraction and redundant storage, it realizes the transition from "moving data" to "moving computing", and supports the comprehensive development of enterprise-level data analysis applications. [0003] At present, data integration and data management are carried out in the full-service unified data center through master data management, unified coding management, etc., but the com...
