Complexity Aspects of Web Services Composition

Our approach primarily lies into: (i) extending the interface of individual Web services in order to reason about their recovery and concurrency capabilities, and (ii) proposing

This approach allows: (i) modeling SBAs in terms of functional and non-functional users’ requirements, (ii) discovering the required WSs, (iii) selecting the most appropriate

Graph-based slicing that eliminates unnecessary tran- sitions and nodes produces an output that will not be a sub graph of the original. Although we term this amorphous slicing it

Dans notre cas, nous nous sommes basés sur le modèle de composant de l’approche IASA (Integrated Approach to Software Architecture) définie dans le contexte

We propose, hence, a framework named D&A4WSC which allows to model the WSC by oWF-nets, to check their compati- bility with the model checker NuSMV and to translate them if they

With the increasing use of the platform independent software architecture such as web-based applications, web services exist in distributed environments. There- fore a web service

Although existing approaches, such as Dynvoker [6], already cover the generation of user inter- faces for single web services dynamically, no solution is available for

For an alphabet of size at least 3, the average time complexity, for the uniform distribution over the sets X of Set n,m , of the construction of the accessible and
