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.

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.

Composite service execution Petri Net and service composition optimization
Proceedings of 2012 IEEE International Conference on Service Operations and Logistics, and Informatics, 2012Web services are becoming the most promising technology for cloud computing. When a single web service fails to satisfy service requestor's multiple function demands, web services need to be configured together to form a service composition with cost and other constraints.

Automatic Web Service Composition
2006 IEEE International Conference on Services Computing (SCC'06), 2006The tutorial aims at providing a deep comprehension of the Web Service Composition problem and automated techniques to tackle it. Web Service Composition is currently one of the most hyped and addressed issue in the Service Oriented Computing. Starting from an analysis of current technologies and standards for Web Service Composition, the tutorial will

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.

Views in composite Web services
IEEE Internet Computing, 2005The authors present a view-based approach for tracking personalized Web services. To guarantee proper handling of user preferences during Web service execution, a view can zoom into the specification that composes the Web services. As time advances, the location changes, or constraints on the environment are satisfied, the deployment of a view over a ...

Web Services and Their Composition
2001Web Services gained a lot of attention in the software industry over the last couple of months (e.g. [1],[2], [3], [4], [5], [6]). Roughly, a web service is any piece of code that can be interacted with based on Internet technology.

Composition of services with mobile code
Proceedings. First and Third International Symposium on Agent Systems Applications, and Mobile Agents, 2001Mobile code is slowly gaining acceptance but it is still not clear where it is really useful. If not used judiciously it may incur greater complexity of programming and degradation of performance. This paper shows that mobile code is particularly well-suited as a glue for the composition of immobile services, where flexibility and extensibility are ...

Adequate monitoring of service compositions
Proceedings of the 2013 9th Joint Meeting on Foundations of Software Engineering, 2013Monitoring is essential to validate the runtime behaviour of dynamic distributed systems. However, monitors can inform of relevant events as they occur, but by their very nature they will not report about all those events that are not happening. In service-oriented applications it would be desirable to have means to assess the thoroughness of the ...
