地质灾害领域本体的研究与应用

Research and Application of Geological Hazard Domain Ontology

引入了由斯坦福大学医学院开发的七步法,并采用OWL DL语言描述本体,利用目前成熟的且流行的本体可视化构建工具Protégé完成地质灾害信息领域本体库的构建。基于行业标准、地质灾害信息处理标准、专家知识等相关标准,建立地质灾害领域本体。用OWL形式化描述基于多层结构的地质灾害空间数据本体应用模型来实现三层地质灾害本体。以具有优势的三峡库区丰富地质灾害资料为依托,以地质灾害多源异构空间信息集成与共享为主线,引入本体理论和GeoSciML,研究建立基于顶级、领域及应用多层本体的地质灾害空间数据语义集成和共享模型,实现地质灾害信息系统数据集成和应用集成,目标是解决横向各部门间的有效沟通和信息共享,以及单体灾害和群体灾害发生时的应急指挥和决策支持等问题。

Seven-step method developed by Department of Medicine in Stanford University is introduced to establish geo-hazard domain ontology,and OWL DL is applied to describe the domain ontology in this paper.Protégé is developed by Stanford University,which is a mature and popular visual ontology building tools,is used in the establishment,management and inquiry access of the geological hazard information ontology.On the basis of related standards such as industry professional standard,geological hazard information processing standard and expert knowledge,geo-hazard domain ontology can be set up.According to the multi-level structure,geological hazard spatial data ontology application model is designed to implement the three level of geological hazard ontology with formalized representation by using OWL.Based on the abundant geological hazard data of Three Gorges Area in China,taking the multi-source heterogeneous geological hazard spatial information integration and sharing for the main line,the introduction of the ontology theory and GeoSciML for the new technical means,geological hazard ontology is applied to realize data and application integration and resolve the problem of decision making when single hazard or group hazards occur.Ontology is used to carry out semantic sharing model to improve interoperability capacity of geological hazard information system.
