MFI4Onto: Towards Ontology Registration on the Semantic Web

Recently, ontology has become the key technique to annotate semantics and provide a common foundation for various complex resources on the semantic web. Efficient registration is the fundamental basis of other applications based on ontology, but extant registry mechanisms are insufficient to register semantic information and enable interoperation based on them. So in this paper, MFI4Onto is proposed as a common framework to register ontology and its evolution information for semantic interoperation between ontologies and information systems based on them. Furthermore, MFI4Onto can also be extended to coordinate with ebXML and enhance its capability for complex resources. Under the guidance of MFI4Onto, it is feasible to perform semantic interoperation between heterogeneous registries on the semantic web.

A MFI4OR-based Approach of Semantic Annotation for Web Service

Compare to the traditional annotation technology for web service, a novel approach for the semantic annotation to web service based on MFI4OR is proposed in the paper. This proposal permits multi-ontology based annotation to web service in the same domain which will lead to the flexible annotation, and then the flexible publication and discovery of web service in Web Service Registry (WSR). The result of experiment illustrates the efficiency of web service discovery and the degree of satisfaction to users in WSR is highly improved.

Using MPMR to Support Developing Web Service Applications for Enterprises

As a temporary alliance of enterprises, a virtual enterprise(VE) is tended to share skills and integrate business processes from different firms for customized business requirements. Since it is hard for end-users to combine heterogeneous business processes and obtain Web service-based solutions, this paper proposes MPMR (Metamodel for Process Model Registration) to register business process and Web service in a unified and normative manner and then enable semantic interoperation between them. In this way, the MPMR-based registration information of them can be used to help smoothly translate professional business process requirements into the corresponding solution based on Web services. Finally, a typical case study in urban transportation is demonstrated to show the practice of using MPMR to support development of Web service applications for a VE or the participating enterprises.

Mappings from OWL-s to UML for Semantic Web Services

As a member of resources on Semantic Web, Web Services become increasingly important to realize accurate composition for interoperation between human beings and information systems. In order to address the need for semantic annotation of existing Web Services, a special UML profile can be built upon UML metamodel and MMFI4Ontology Registration for Semantic Web Services described with OWL-s. Then the mappings from OWL-s to UML are defined in detail to indicate that our UML profile and transformation rules can be used to represent services with UML activity models. Efforts on our UML profile and further mappings can enrich the semantics of ubiquitous Web Services, facilitate services modeling for domain experts and make it easy to update current tools for supporting growing services on semantic web.

On Ontology Management in Semantic Web Service Registry

Ontology plays a key role in Semantic Web Service Registry (SWSR) which will add semantic information to web service. There exist some cases that users use different ontologies in the same domain to annotate web service. Therefore in this paper we present an approach to effectively manage the ontologies in SWSR based on ISO SC32 19763-3: MFI-3 (Metamodel Framework for Interoperability: Metamodel for Ontology Registration). We manage these different ontologies and the Same As relationship between them in order to maintain the semantic interoperability of web service based on these ontologies. Finally a prototype of Ontology Management Platform (OMP) is realized.

Towards Service-Oriented Semantic Interoperability Based on Connecting Ontologies

In service-oriented software development, the basic objective is to provide on demand service by discovering and aggregating available service resources. Faced with the distributed, heterogeneous, autonomous and dynamic service resources in Internet, how to provide semantic interoperability support across domains becomes an urgent issue. In this paper, Connecting Ontologies (CO), which are driven by users’ requirements, are proposed as a new method to provide on-demand semantic interoperability support for aggregating services. Then the semantic interoperability based on CO is discussed. In addition, an example in urban transportation domain is given to illustrate the method.
