Background

•Disaster Management

•Spatial Information

•A Case Study

5Applying 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!

6Applying Ontology on Semantic Interoperability of Disaster Management

Interoperability

• System interoperability

• Syntax and structure interoperability

• Semantic interoperability?

Ontology

7Applying 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

How to integrate them?

•Road, highway, lane

•Lake, water source, clean water source

•Building, shelter

10Applying Ontology on Semantic Interoperability of Disaster Management

Road, highway, lane

•Lane is a kind of road•Highway is also a kind of road•Lane is different from highway

Road:Path vehicles and pedestrians

Highway:PathOnly vehiclesWith speed limitation

Lane:Path

Pedestrians

Lake, water source, clean water source

Clean water source:Water on the earth crust

Human reachableWithout poisonous substance

Water source:Water on the earth crust

Human reachable

Lake:A small earth area

Water on the earth crustWater covered

Building, shelter

Building:Walls + roof

Shelter:Walls + roof Firmly built

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?

19Applying 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?
