An Approach to Support Portlet Semantic Interoperation by Using Ontology Based on JSR268

Web portals are integration of enterprise applications and services. The further integration of applications in portal context is actually the problem of portlet interoperation. However, there is not yet a definitive answer to portlet interoperation. This paper focuses on using ontology to support portlet semantic interoperability based on new features of JSR268. The proposed approach maps the portlets to concepts in ontology, and then constructs semantic data associations between such concepts, and finally achieves portlet interoperation based on the data associations. Experimental results show that this proposed approach can achieve application integration in portal without modifications to the applications.
