With the advent of Semantic Web, the fast dissemination of ontologies to represent and share information causes a deep impact on knowledge retrieval, as a whole. In this context, the use of different ontologies to express meaning on the same application domain leads to a kind of "Tower of Babel Effect" on the Web, bringing new problems to the communication among different applications. This problem still remains in service-oriented architectures, considering that a same service can be described by the use of different ontologies and standards. Therefore, the urge of an ontology reconciliation approach arises in order to enable communication despite the differences. This paper focuses on providing a formal description of ontology reconciliation techniques, such as merging, alignment and integration, to provide better understanding of how these techniques can be used on the scope of Semantic Web Services Architecture.
The adoption of service-oriented approach and the increasing of business-to-consumer applications have produced impacts over software development. Traditional tasks, such as discovery of appropriate Web Services, are becoming more and more an individual experience. This paper presents an ontological approach for personalized services that is based on the perception concept. The proposed model considers user preferences, priorities and constraints, the natural starting point for service configuration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
