Semantic Web Services propose to extend the traditional Web Services technologies on the way to consolidate ontology and semantics. This makes it possible to select, integrate and invocate services dynamically. In this paper, an approach of Semantic Web Services discovery is presented. In this approach, the semantic distance is calculated with vector space model at first. Then match web services with...
With the quick increase of web services on the Internet, how to discover proper services efficiently in a large number of web services becomes more and more difficult. Services discovery efficiency can be improved greatly after services have been classified well, so an algorithm of clustering services which uses graph theory and a corresponding algorithm of discover services are proposed in this paper...
In the service collaboration field, there exists the need to combine two or more services together to fulfill a complex goal. Though service composition is an active research field, most of solutions are focused on Web services and lack of the consideration for business-level collaboration. In this paper we present a discovery architecture that supports business-level service composition. In our architecture,...
In the context of distributed and open systems, the dynamic evolution of the distributed entities (or services) and their adaptation is one of the main prevailing challenges. In this paper, our aim is to show that is possible to automate (at least partially) the discovery, the selection and the adaptation of components, on the one hand associating a semantic description based on functional and non-functional...
In semantic Web technologies, searching for a service means to identify components that can potentially satisfy the user needs in terms of outputs and effects (discovery), and that, when invoked by the customer, can fruitfully interact with her (contracting). In this paper, we present an application framework that encompasses both the discovery and the contracting steps, in a unified search process...
The amount of ecological data available electronically is increasing at a rapid rate, e.g., over 15,000 data sets are available today in the Knowledge Network for Biocomplexity (KNB) alone. Using the existing search capabilities of these online data repositories, however, scientists struggle to quickly locate data that are relevant to their needs or that will integrate with their current data sets...
In this paper, we present a new approach for service discovery combining semantic web and peer-to-peer techniques. A reference ontology is used to describe and discover services in our approach. We do not need a central point of control at any time. All information required for service description and discovery is completely distributed across the nodes of a peer-to-peer overlay network. We describe...
