Construction of Typhoon Disaster Chain Knowledge Graph Based on Disaster Risk Survey Knowledge
摘要
Abstract
Based on the disaster system theory and Knowledge graph construction technology,we use the tech-nical specifications for risk assessment of various disasters provided by the first national comprehensive risk survey of natural disasters,and supplement other existing literature and historical typhoon disaster cases to extract the dis-aster causing factors,disaster carriers and the disaster chain relationship between them;Based on the spatiotempo-ral topological relationship theory in GIS,extract the spatiotemporal topological relationship words between the dis-aster bearing entity and the spatial features of the disaster causing factors;The disaster verbs and disaster degree words are extracted from the news and social media corpus of typhoon disaster reports based on Natural Language Processing technology,which are used as relational words to describe the disaster situation of disaster victims;On this basis,a knowledge network with the"disaster causing factor disaster chain relationship disaster carrier"triplet as the basic chain of the disaster chain was constructed,thereby constructing a comprehensive typhoon disaster chain network.The knowledge network consists of 59 nodes and 787 triplets.Through Neo4j Graph database,the complete typhoon disaster chain network is displayed more concretely and vividly,which lays the foundation for fur-ther typhoon disaster network analysis and knowledge reasoning.关键词
