We extend the service abstraction in the Open Grid Services Architecture[12] for Quality of Service (QoS) properties. The realization of QoS often requires mechanisms such as advance or on-demand reservation of resources, varying in type and implementation, and independently controlled and monitored. Foster et al. propose the GARA [10] architecture. The GARA library provides a restricted repres...

Service discovery and service aggregation are two crucial issues in the emerging area of Service-oriented Computing (SoC). We propose a new technique for the discovery of (Web) services that accounts for the need of composing several services to satisfy a client query. The proposed algorithm makes use of OWL-S ontologies, and explicitly returns the sequence of atomic process invocations that th...

Service discovery is a fairly new field that kicked off since the advent of ubiquitous computing and has been found essential in the making of intelligent networks by implementing automated discovery and remote control between devices. This paper provides an overview and comparison of several prominent service discovery mechanisms currently available. It also introduces the At Home Anywhere Ser...

Existing methods and technologies for Web services discovery mainly consist of two models: service matching based on grammar and based on semantics. With keywords service matching method, we introduce text information retrieval technology with vectors and concept lattice theory. Then a web service discovery algorithm using eigenvectors is put forward. It orders the Web services by correlation a...

-Service discovery technologies enable services to advertise their existence in a dynamic way, and can be discovered, configured and used by other devices with minimum manual efforts.In order to achieve efficient service discovery in large scale Mobile Ad hoc Networks (MANETs) we have proposed a scheme that integrates service discovery with cluster based routing by piggybacking service informat...

The process of Web Service Discovery consists of finding the best match amongst a collection of available services to a particular problem or kind of problem. In our particular area of interest, mathematics, this matching process will involve both mathematical ("can it solve my problem?") and non-mathematical ("am I authorised to use it?", "will the resources needed to solve my problem be avail...

Web services technologies promise to create new business applications by composing existing services and to publish these applications as services for further composition. The business logic of applications is described by abstract processes consisting of tasks which specify the required functionality. Web services provision refers to assigning concrete Web services to perform the constituent t...

The automatic location of services that fulfill a given need is seen as a key step towards dynamic and scalable integration. In this paper we present a model for the automatic location of services that considers the static and dynamic aspects of service descriptions and identifies what notions of match and techniques are useful for the matching of both. Our model presents three important featur...

Annotation paths are a new method for semantic annotation which overcomes the limited expressiveness of semantic annotations by concept references as defined in the SAWSDL standard. In this work we show some preliminary evaluation of the feasibility of annotation paths for web service discovery. The experiments suggest that annotation paths can capture the semantics of XML schemas and web servi...
