Composition of component services
Seventh IEEE International Symposium onObject-Oriented Real-Time Distributed Computing, 2004. Proceedings., 2004We consider a component to be an encapsulated hardware-software unit that can be used as a building block in the construction of a larger system and that delivers a specified service across a component interface. The problem of composition of a set of components can be broken down into the following two subproblems, the composition of the component ...

Service Composition with Directories
2006This paper presents planning-based service composition algorithms that dynamically interact with a potentially large-scale directory of service advertisements in order to retrieve matching service advertisements on demand. We start with a simple algorithm for untyped services, similar to a STRIPS planner.

"Service Hyperlink" for Exploratory Service Composition
IEEE International Conference on e-Business Engineering (ICEBE'07), 2007Service orchestration logics can be difficult to be totally pre-fabricated as composite services when facing uncertain requirements. It is sometimes indispensable to get end users involved. However, we should not expect end users do programming as computer professionals.

Middleware services for web service compositions
Special interest tracks and posters of the 14th international conference on World Wide Web - WWW '05, 2005WS-* specifications cover a variety of issues ranging from security and reliability to transaction support in web services. However, these specifications do not address web service compositions. On the other hand, BPEL as the future standard web service composition language allows the specification of the functional part of the composition as a ...

Service composition for generic service graphs
Multimedia Systems, 2006Service composition is a promising approach to multimedia service provisioning, due to its ability to dynamically produce new multimedia content, and to customize the content for individual client devices. Previous research work has addressed various aspects of service composition such as composibility, QoS-awareness, and load balancing.

Security Policy Composition for Composite Services
2008 Eighth International Conference on Web Engineering, 2008An application based Service-Oriented Architecture(SOA) consists of an assembly of external services and the application is called as a composite service. Acomposite service could be implemented by other composite services hence the application could have a recursive structure, which is one of the features of SOA application.

Identifying Optimal Composite Services by Decomposing the Service Composition Problem
2011 IEEE International Conference on Web Services, 2011For a Web service composition to satisfy a user's needs, it must not only provide the desired functionality, but also have nonfunctional properties (e.g., reliability, availability, cost) that are acceptable to the user. In the recent past, several techniques have been developed and deployed to identify a composite service that conforms to the ...

A Model of Pervasive Services for Service Composition
2005We propose a formal definition of a pervasive service model targeting the very dynamic environments typical of mobile application scenarios. The model is based on a requirement analysis and evolves from existing service definitions. These are extended with pervasive features that allow for the modeling of context awareness, and pervasive functionality ...

Composition of Services on Hierarchical Service Models
2012In this paper we define a concept of service model, and introduce hierarchical service models suitable for large service parks. We describe a method for handling higher-order workflows that we use for automatic composition of services. We give a description of a specification language suitable for representing hierarchical service models.

Workshop on Automatic Service Composition
Proceedings of the 2010 Conference of the Center for Advanced Studies on Collaborative Research - CASCON '10, 2009In Service-Oriented Architecture (SOA), applications can be assembled by a set of existing distributed services spanning across organizations and platforms. SOA increases reuse and cooperation among services. Therefore, applications can be built in a rapid way with relatively low cost.
