Build-up of Ontology-Based Real-estate Information System Integration Platform

摘要

Ontology technology resolves the problems of semantic heterogeneity in information integration,which realizes the semantic interoperability between information systems.In order to realize information sharing and data exchanging effectively between real-estate information systems,in this paper the author introduced ontology into heterogeneity information integration for real-estate information systems.Firstly systematically analyzed the origins of heterogeneous data in real-estate information systems,then designed ontology-based information system integration platform with protege 2000 and described the work process of the platform,finally verified the feasibility of the prototype system.At present ontology has wild-scale application in numerous fields,but it is seldom in real-estate profession.Its realization is to partially resolve semantic heterogeneity existing real-estate enterprises.
