Composition of service specifications
Proceedings Sixth International Conference on Network Protocols (Cat. No.98TB100256), 2002The service specification ss(P) of a protocol P defines the services provided by the protocol and its protocol specification ps(P) specifies the rules of message exchange to ensure the service. Protocol composition has been advocated as an attractive way to design complex protocols.

One of the striking advantages of Web Service technology is the fairly simple aggregation of complex services out of a library of other composite or atomic services. The same is expected to hold for the domain of Semantic Web Services such as those specified in WSMO or OWL-S.

Distributed Service Composition in Internet of Services
2021 IEEE International Conference on Services Computing (SCC), 2021To meet coarse-grained user requirements, many service composition approaches have been put forward in the past 20 years. The service composition constructs a service workflow by aggregating services to meet users’ functional and non-functional requirements.

Cooperative Service Composition
2012Traditional service composition approaches are top-down(using domain knowledge to break-down the desired functionality), or bottom-up (using planning techniques). The former rely on available problem decomposition knowledge, whilst the latter rely on the availability of a known set of services, otherwise automatic composition has been considered ...

We have developed a tool to allow users who are not programmers to assemble non-trivial service compositions. The tool uses templates and background reasoning to reduce the mental effort needed by users when they compose services, and provides immediate feedback about the consequences of any decisions made by its users.

, 2008 Currently, composition of web services is done by orchestration. An orchestration is a workflow that combines invocations of individual operations of the web services involved. It is therefore a composition of individual operations, rather than a composition of entire web services.

Relational Service Composition
2009 IEEE International Conference on Semantic Computing, 2009Although the service composition problem has been widely addressed, automatically composing a service from existing services is still very difficult. This paper focuses on the composition problem for relational web services. It considers answering complex queries using a set of available relational services collectively.

Both the agent and Grid communities develop concepts for distributed computing, however they do so with different motivations. This paper demonstrates how the flexible coordination technique of interaction protocols, from the field of multiagent communication, can be used to model the processes found in scientific workflow, a typical composition ...

A geographical information system (GIS) is a system that captures, analyzes, and manages any spatially referenced data. One common problem in the GIS community is how to generate and publish customized Web maps. The existing solutions either deal with spatial data directly which does not allow for applying the customized features, or require and rely ...

Planning and verifying service composition [PDF]
Journal of Computer Security, 2009 A static approach is proposed to study secure composition of services. We extend the λ-calculus with primitives for selecting and invoking services that respect given security requirements. Security-critical code is enclosed in policy framings with a possibly nested, local scope. Policy framings enforce safety and liveness properties.
