Embodiment Construction

[0055] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0056]The present invention provides a method for constructing a power grid knowledge graph, such as figure 1 shown, including the following steps:

[0057] S1. Collect power grid related content and organize power grid corpus. Corpus is the basis of natural language processing, and the power grid field is very different from the common open field. There are many proper nouns, and there are a lot of idioms and abbreviations with different meanings. In order to ensure the accuracy and reliability of subsequent processing, the present invention Organize the grid corpus by collecting relevant content in the grid:

[0058] S11. Construct a dictionary of professional nouns. The diction...

Abstract

The invention discloses a power grid knowledge map construction method and system, aiming at solving the technical problem of lack of practical and efficient knowledge map construction tools in the field of power grid technology in the prior art. It includes: collecting power grid related content to organize power grid corpus; constructing and training a natural language processing model according to the power grid corpus; extracting power grid knowledge based on the natural language processing model, and storing the extraction results in a graph structure database. The invention can effectively extract the power grid knowledge, build a knowledge map in the power grid field, and provide support and guarantee for the subsequent application of the knowledge map.

Description

technical field [0001] The invention relates to a method and a system for constructing a power grid knowledge map, belonging to the technical field of power grid knowledge map. Background technique [0002] The power grid includes three major links: power generation, transmission and distribution. The entire physical structure is a huge and complex network. Due to the characteristics of the physical structure of the power grid, it is very suitable to use the graph data structure to create the power grid data model, and the graph data structure does not exist. Associative foreign keys are associated between relational nodes, and their performance is greatly improved compared to traditional data structures. [0003] Knowledge graph is a technical system that includes a variety of technologies such as knowledge representation, knowledge extraction, knowledge reasoning, knowledge retrieval, etc. Knowledge graphs can be used in scenarios such as question answering systems, logic ...
