Domain Ontology Component-Based Semantic Information Integration

Research on architecture of domain ontology component-based information semantic representation and integration is studied. Domain ontology component, a "loosely coupled" approach in the use of ontology, is advocated. As a case study, a prototype for agricultural policy-oriented domain ontology component-based semantic information integration system (APODOCSIIS) is established. Ontology plays a key role in providing a shared terminology and supporting for the semantic representation and integration process. The architecture allows APODOCSIIS-based applications to perform automatic semantic information integration of agricultural policy text at more length: semantic matching of concepts between different ontology components, domain ontology component-based dynamic semantic annotation of unstructured and semi-structured content, semantically-enabled information extraction, indexing, retrieval, integration, as well as ontology management, such as querying and modifying the underlying ontology components. Main frame of this architecture have been implemented and concrete integration example are given.
