基于大语言模型的水利工程运行管理质量概念模型及知识图谱自动化构建
Automated construction of schema and knowledge graphs for the operation and management quality of hydraulic projects based on large language models
摘要
Abstract
At present,the quality management related data of hydraulic projects are mostly stored in unstructured text with a low degree of digitization,making it difficult to meet the higher requirements for high-quality develop-ment.To overcome the shortcomings of the current knowledge graph and knowledge graph schema construction meth-ods,which rely heavily on manual labor and have poor efficiency.This paper proposes an Explore-Construct-Filter(ECF)framework based on large language models(LLMs)to achieve automated construction of conceptual models and knowledge graphs for the quality management of hydraulic project operation.The framework uses LLMs to first discover the entities and relationship types of the knowledge graph,and then designs and generates a conceptual model of the knowledge graph.Subsequently,under the guidance of the conceptual model,instances are extracted from the data source to construct a knowledge graph.Finally,design a filtering mechanism to remove triplet noise from conceptual models and knowledge graphs,ensuring accuracy.By setting the seed text set and the entire text set data,the various components of the ECF framework are evaluated and compared with the existing methods.The results show that the ECF framework performs well in the automatic construction of conceptual models and knowledge graphs,with an accuracy rate 23％higher than that of existing methods,thus optimizing the efficiency of knowledge graph construction,and providing technical and theoretical support for the standardized operation and steady prog-ress of water conservancy engineering.关键词
