摘要
将知识图谱技术与地缘环境领域相结合,剖析地缘环境知识的内涵和特点,提出基于多源异构地缘环境数据构建地缘环境知识图谱的基本框架,设计地缘体、地缘事件等知识表示模型,对地缘知识查询、地缘事件演化分析和地缘环境影响力分析进行了实验。结果表明:(1)基于地缘实体能够快速关联查询地缘要素知识、地缘事件知识和地缘专家知识等各类地缘知识;(2)根据地缘事件之间的因果、顺承等关系可以快速分析事件的发展脉络,厘清地缘环境之间的相互影响规律;(3)大规模网络图关联了地缘体、环境、事件等多源异构信息,为地缘环境分析提供了基础的信息底图。
This paper combines the knowledge graph with geo-setting,firstly,it analyzes the connotation and characteristics of geo-setting knowledge,and puts forward the basic framework of geo-setting knowledge graph,which bases on the multi-source heterogeneous geo-setting data,and discusses its key technology;Then,the article designs the knowledge representation models of geo-body and geo-event.Finally,the application analysis is carried out from the following aspects:fast search of geo-setting knowledge,correlation analysis and mining of geo-setting knowledge.The results show that:(1)Based on geo-entity,geo-element knowledge,geo-event knowledge,geo-expert knowledge and other geo-knowledge can be queried quickly.(2)The causality and consequent relationship between geo-events can quickly analyze the development context of events and clarify the law of interaction between geo-setting.(3)A large-scale network graph that correlates multi-source heterogeneous information such as geo-objects,environments,events,etc.,provides a basic information base map for geo-setting analysis.
