In this paper, we consider semantic service discovery in a global computing environment. We propose creating a dynamic overlay network by grouping together semantically related services. Each such group is termed a community. Communities are organized in a global taxonomy whose nodes are related contextually. The taxonomy can be seen as an expandable, flexible and distributed semantic index ove...

In future ubiquitous communication systems, a service can be anything and introduced by anybody. Consequently, same or equivalent services may have different names and services with same name or type may be completely different. Existing service discovery systems are incapable of handling these situations. We propose a service discovery, which is able to discover all these new service types. In...

In this paper, we describe a novel application of the Web Services model for end-user information discovery needs rather than for the traditional business-to-business applications. We describe a specialization of Web Services for information providers and demonstrate, through an exemplary unified information discovery console, how consumers can easily customize their favorite information source...

Sensor network is a novel technology about acquiring and processing information. This paper introduces the basic interaction patterns between requesters and providers of services during a typical Service Discovery task. It discusses existing service discovery protocols and provides a preliminary analysis of the mechanisms for service and resource discovery in the Wireless Sensor Network domain....

As more services become available on networks, and as ad hoc network grows in popularity, the problem of service location will grow. Service location is the detection of a service through automated means, and the subsequent configuration of the service user to use that service. A number of service discovery protocols currently exist, but there is no known framework for the evaluation and compar...

The Web Service Modeling Ontology (WSMO) provides the conceptual framework for semantically describing web services and their specific properties. The Web Service Modeling Language (WSML) is a formal language for annotating web services with semantic information, which is based on the WSMO conceptual framework. Service discovery, i.e., the automatic location of services that fulfill a user goal...

Service Discovery is a core enabling technology for users in mobile and ubiquitous computing. However, most of the existing protocols for service discovery works on a low level and do not provide support for higher-level service abstraction, composition, and orchestration. Nor do they support service discovery tailored to the mobile user’s context. This paper presents the principles of Acitvity...

--Web services are playing an important role in organization to improve their business. As web service applications are platform independent so large scale distributed systems can be developed easily using web services. As per organization requirements it is very difficult task to finding most suitable web service from large collection of web services for successful execution of applications. K...
