The ever-growing number of services on the WWW provides enormous business opportunities. Services can be automatically discovered and invoked, or even be dynamically composed from more simples ones. Agent technology provides designers with an interaction-oriented way of designing open software systems [3]. In this paper we concentrate on the problem of dynamic service discovery in multi-agent s...

Current service description and composition approaches consider simplistic method invocation. They do not accommodate ongoing interactions between service providers and consumers, nor do they support descriptions of legal protocols of interactions among them. We propose richer representations which enable us to capture more of the semantics of services than current approaches. Further, we devel...

This paper presents a test and deployment infrastructure that has been developed to validate the ICENI Grid Middleware. Services have been developed to monitor the different steps in the life of the middleware from its compilation to its execution. We will show how these services can be composed to provide a full validation of the architecture and the functionalities of ICENI. We also present a...

In this paper, a model is presented which allows the composition of web services by means of a special web service, named WSInterConnect. Such a service might be used in a portal environment to allow interactive services lookup and creation of permanent composed services in the design stage, and for efficiently resolving missing parameters during the runtime of a process. The portal integration...

Houses of tomorrow will be equipped with many sensors, actuators and devices, which collectively will expose services. Such services, composed in an automatic way, and invokable through adaptive user interfaces, can support human inhabitants in their daily activities. In this paper we present the approach and some results of the SM4All EU project (http://www.sm4all-project.eu/), which is invest...

—SOA is now the reference architecture for medical imaging processing on the grid. Imaging services must be composed in work ows to implement the processing chains, but the need to handle end-to-end qualities of service hampered both the provision of services and their composition. This paper analyses the variability of functional and non functional aspects of this domain and proposes a rst arc...

Ensuring dependability of composite Web services, dynamically composed of component Web services, is an open issue. One of the main difficulties here is due to the fact that component Web services can and will be upgraded online. The challenge is then to ensure that the overall dependability of the composite service is not undermined. The solutions we propose in this position paper make use of ...

The emergence of open, composable Internet services and mashups means that services cannot be composed in a centralised manner. Despite this, cross-cutting constraints might exist between services, stemming from, e.g., security. Especially when used with mobile devices, these service compositions need to be constructed at runtime. This paper proposes a knowledge-based approach for dynamically f...

In this paper, we present an approach for the implementation of semantically enriched services in Enterprise Application Integration (EAI). We present an integration platform based on a Service Oriented Architecture (SOA) which consists of a service registry, a process designer and a run-time engine. There are some additional components for realizing semantic enrichment of services and composed...
