5 Applying Ontology on Semantic Interoperability of Disaster Management Disaster Management Risk Management and Emergency Response Lots of actors Various kinds of information in different formats, different levels, different domains Interoperability is urgent!

6 Applying Ontology on Semantic Interoperability of Disaster Management Interoperability System interoperability Syntax and structure interoperability Semantic interoperability? Ontology

7 Applying Ontology on Semantic Interoperability of Disaster Management Spatial Information Semantic information should be represented Context-related information should be extracted Implicit relationships between concepts should be computed

8 Applying Ontology on Semantic Interoperability of Disaster Management A Case Study SII (Spatial Information Infrustructure) City planner: road lake building farmland Fire brigade: highway lane water source Medical center: shelter clean water source

18 Applying Ontology on Semantic Interoperability of Disaster Management Research Problem What is the added values and limitation of applying ontology to integrate the (spatial) information efficiently and show to users friendly in time when the disaster happens?

19 Applying Ontology on Semantic Interoperability of Disaster Management Subquestions How to build the ontology for the data schema? Starting from the abstract level or the concrete level? What is the most efficient way to build the ontology? How to find the corresponding link between two ontology? Is it necessary and possible to build a domain ontology to be referred to by each ontology? How to evaluate whether an ontology is built efficiently or not? What kind of information is ignored or changed when building ontology? What kind of information do actors in Disaster Management want? Which kind of forms should the extracted information be represented? How to evaluate whether the ontology method could efficiently represent the semantic information than non-ontology method? What kind of criteria could be used? time cost?
