ODACE SLA is a semantic matching approach between client intentions and provider offers. Its objective is to bridge the semantic gap between these intentions and offers. ODACE SLA is based on inference techniques and semantic interpretation. It relies on four main steps. The first step of this approach consists in generating correspondences between the client and the provider terms by assigning a certainty degree for their equivalence. The second step corrects and refines these certainties. In the third step, we evaluate the matching results. In case of compatibility, a draft version of an agreement is automatically generated.
