Web service composition has become the optimum technique for Service Oriented Architecture applications because it provides a way to obtain value-added services by combining several Web services. One key issue is that service composition must meet user’s deadline requirements. In this paper we focus our attention on modeling and analyzing time-related properties in service composition. A model ...

Service-oriented architecture (SOA) is a software design paradigm for creating highly modular, distributed applications.Web services can implement welldefined, atomic functions which can be composed into high-level business processes. The composition of clearly separable modules is one of the key advantages of SOAs. This article provides an overview of research, challenges, and competitions in ...

Web Service Discovery can be described using OWL-S. It follows web service discovery model because it has conceptual and trivial semantic web service descriptions using service profile ontology of OWL-S. The Web Service Discovery model uses Web Service matchmaking algorithm which enlarges matching techniques used in Structural Case Based Reasoning, allowing the retrieval of Web services based o...

State-of-the-art workflow languages for web services are much better suited for web service composition than traditional general-purpose programming languages. Such workflow languages, however, still require a lot of in-depth technical knowledge. In order to facilitate service composition without requiring such in-depth technical knowledge, a higher level of abstraction is required. We therefor...

Web service composition is a distributed model to construct new web service on top of existing primitive or other composite web services. The advantage of web service composition has already been demonstrated and highlighted for its capability to compose autonomous services to achieve new functionality. However, an important question is whether this distributed model will be realized or not, du...

Web service has been playing a magnificent role in the field of application development. It facilitates giving a global touch to standalone applications components to interact with each other via interfaces and form larger application systems. Web service users who seek for single web service or composition of web services face a lot of problems regarding its discovery. Discovery of suitable we...

The semantic web service composition systems can also be implemented using the concept of multi-agent systems. In this approach, each of the agent capability is used to serve a particular service request. Paper presents two models for multi-agent based semantic web service composition process, differing on the point of using a coordinator for controlling the process or not. Further, based on on...

We show how the service composition problem can be viewed as a planning problem in which state descriptions are ambiguous and operator definitions are incomplete. We then discuss the problem of interpreting documents (which describe the world state), and introduce a semantic type matching algorithm. The matching algorithm together with an interleaved search and execution algorithm allow for bas...
