Abstract

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 Recent works have demonstrated that this approach is not sufficient to discover relevant components In this paper we argue that, in many situations, the service discovery should be based on the specification of service behavior 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 A prototype is presented which takes as input two BPEL models and evaluates the semantic distance between them; the prototype provides also the script of edit operations that can be used to alter the first model to render it identical with the second one.
