Title
Enabling Semantic Mediation in DaaS Composition: Service-Based and Context-Driven Approach.
Abstract
As commonly agreed, Web services fall into two categories depending on their functionality world-altering services and Data-as-a-Service DaaS. Much work has been done on automatic DaaS discovery and composition, such as the query rewriting approach proposed by the database community. In this context, DaaS is described as Parameterized-RDF View over Domain Ontology DO. However, the DO is unable to capture the different perspectives or viewpoints for the same domain knowledge. This limitation raises semantic conflicts between pieces of data exchanged during DaaS composition process. Thus, mediators are typically required to reconcile potential conflicts. In this paper, the authors propose a service-based approach for automatically inserting appropriate mediation services in DaaS compositions to resolve incompatibilities in their data flow. Also, the authors present a context-driven approach to support semantic mediation between composed DaaSs. The implementation and the experimental evaluations performed showed us satisfactory results.
