AI Technical Summary

Technical Problem

Traditional power safety management methods rely on static documents and manual interpretation, which makes it difficult to understand the complex semantics, time constraints and logical relationships of policy provisions. They cannot support cross-system and cross-time period correlation reasoning and dynamic updates, and lack real-time monitoring and quality verification, resulting in inaccurate Q&A results and data redundancy.

Method used

A knowledge graph-based approach is adopted to acquire power safety policy data and transform it into temporal facts, construct a knowledge graph, and achieve dynamic updates through differentiated incremental storage and snapshot reconstruction strategies. Combined with data quality detection and model optimization, this ensures efficient knowledge management and accurate question answering.

Benefits of technology

It enables efficient and dynamic management of power safety regulations, supports cross-time period correlation reasoning and accurate question answering, improves data reliability and decision support capabilities, and ensures the efficiency and stability of the method.

Abstract

The invention provides an electric power security system question and answer method based on a knowledge graph and related equipment. The method comprises the following steps: acquiring electric power safety system data; converting the electric power safety system data into tense facts; constructing a knowledge graph based on the tense facts; and in response to a user query event, retrieving the tense fact conforming to the temporal context in the knowledge graph, and generating a reply result corresponding to the user query event based on the tense fact. According to the embodiment of the invention, dynamic management and query of multi-source heterogeneous data are realized through temporal modeling, and version reconstruction is supported by adopting an incremental storage and snapshot strategy. The trigger type retraining mechanism dynamically adapts to new data and laws and regulations, and the conflict judgment mechanism solves multi-source contradictions, so that the efficiency, accuracy and decision support capability of power safety system management are remarkably improved, and technical guarantee is provided for industry compliance management and intelligent question and answer service.
