Web services discovery and integration based on behavior specification

Résumé :

The capability to easily find useful services (software applications, software components, scientific computations) becomes increasingly critical in several fields.

Current approaches for services retrieval are mostly limited to the matching of their inputs/outputs possibly enhanced with some ontological knowledge.

Recent works have demonstrated that this approach is not sufficient to discover relevant components. In this talk we argue that, in many situations, the service discovery should be based on the specification of service behavior (in particular, the conversation protocol).

The idea behind is to develop matching techniques that operate on behavior models and allow delivery of partial matches and evaluation of semantic distance between these matches and the user requirements.

Consequently, even if a service satisfying exactly the user requirements does not exist, the most similar ones will be retrieved and proposed for reuse by extension or modification.

To do so, we reduce the problem of behavioral matching to a graph matching problem and we adapt existing algorithms for this purpose.

We adress also briefly the problem of resolving differences between services interafces and protocols by developping adapters.
