An applied ontology: A semantic query builder for health GIS system

GIS information is important for e-Health surveillance because such information is required for monitoring, exchanging and shared across health GIS systems. However, interacting with the health GIS system is difficult for the users who may have less knowledge about GIS systems. This paper proposes a semantic query builder that provides a query service and can interact with health GIS systems. The semantic query builder receives the semantic query and translates such queries into a SQL query to allow querying information from databases stored in the health GIS system. It delivers GIS tuple data - the data from the map service is provided by the health GIS system. With the proposed semantic query builder, the users who may have less knowledge of SQL and GIS system are able to specify the query flexibly which meets their requirement.
