Research on Construction Method of Water Resources Carrying Capacity Evaluation Indicator System Based on Knowledge Graph
In order to solve the complexity problem of water resources carrying capacity influencing factors,this pa-per introduces knowledge graph technology and takes massive research results as data sources.The indicator entities set is established through knowledge extraction.Entropy value and variation coefficient is coupled to enhance the representa-tiveness of indicators.Knowledge merging based on the maximum information coefficient reduces the crossover and dupli-cation of indicators.Grey correlation knowledge reasoning is used to select the key indicators.Finally,high-quality knowledge based on expert consultation is formed and the indicator knowledge such as entities,relationships,and attrib-utes is stored using the Neo4j graph database.This indicator system based on knowledge graph is not only knowledgea-ble,but also comprehensive,which solves the problem of complex modeling of influencing factors of water carrying ca-pacity,and provides a new method for the construction of water resource carrying capacity evaluation indicator system.
