Personalized u-Portal System with Ontology and Web Services

Most portal systems provide simple web services in existing web environment but cannot support semantic web environment. Moreover, current portal systems are not adequate to compose personalized services. We also need semantic portlet search methods using portlet ontology, which can support ubiquitous environment, as well as portlet API that supports users’ access to u-Portals through various types of terminal equipment. This paper constructs a user-centered customized web service u-portal system that supports semantic web service search and composition through a ubiquitous portal engine.
