The success of the Web service technology has brought topics such as software reuse and discovery once again on the agenda of software engineers. While there are several efforts towards automating Web service discovery and composition, many developers still search for services via online Web service repositories and then combine them manually. However, from our analysis of these repositories, i...

The current internet has seen a tremendous growth of web services as an important technology for exchanging information, computing resources and programs online. With these increasing acceptance and existence of internet services, it has become high importance to have effective and accurate recommendation systems. It was observed that vast majority of web services are without associated with a ...

The use of geographic data through Web services shows the geospatial Web Services (GWS). A growing number of GWS designed to interoperate spatial information over the network have emerged. GWS are changing the way in which spatial information systems and applications are designed, developed, and deployed [1]. When GWS is increasing, the difficulty of the service discovery increases too. The ser...

Web Services standard has been broadly acknowledged by industries and academic researches along with the progress of web technology and e-business. Increasing number of web applications have been bundled as web services that can be published, positioned and invoked across the web. The importance of the issues regarding their publication and innovation attains a maximum as web services multiply ...

Service-Oriented Architectures enable the consumption of existing services in a standardized way to solve some specific needs. In order to consume some services made available by cooperating parties e.g. for performing some business activity, such services must be located based on different criteria. In this paper, we investigate how the semantic description of the capability of Web services an...

Semantic Web Services (SWS) propose to extend the traditional Web Services technologies on the way to consolidate ontologies and semantics. This makes it possible to select, integrate and invocate services dynamically. In this way, services are able to dynamically adapt themselves to changes without human intervention. The main purpose of this paper is to present an algorithm for matching SWS. ...

service oriented enterprises (soes) are subject to constant change and variation. in this paper, the changes are considered from an economic perspective based on service culture notion. once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. we construct a game theoretic model trying to capture the possible conflicting i...

Semantic Web Services are the key technology providing services for the users’ convenience in the semantic web environment. Many companies in various fields are researching and developing languages for constructing Semantic Web Services such as DAML-S, WSDL, X-LANG and BPEL4WS. DAML-S is a method that accesses the existing Web Service method from a semantic web environment. However, the current...

The Web Services infrastructure is a distributed computing environment for service-sharing. Mechanisms for Web services Discovery proposed so far have assumed a centralized and peer-to-peer (P2P) registry. A discovery service with centralized architecture, such as UDDI, restricts the scalability of this environment, induces performance bottleneck and may result in single points of failure. A di...

The most straightforward but also most inflexible configuration approach for invocation of remote services is to hard wire the location, interface, behavior and other properties of remote services into the local application. Loosely coupled decentralized systems call for solutions that are more flexible and can seamlessly adapt to changing conditions. While advances have recently been made in t...
