Abstract
Current service discovery techniques mainly depend on keyword matching approaches. That could lead to a high service retrieval recall whereas it leads to a low service retrieval precision. To overcome this problem, a service matchmaking process should use the semantics of both the service and the user. Hence, we propose the G + conceptual model that explicitly captures the service/user objectives, scenarios and contexts. Scenarios capture the required snapshots of the service/user behaviour. Based on the G + model, we introduce the PILLAR conceptual model that captures multiple semantic descriptions of the service. The PILLAR concept is also used to semantically model the user request. Different domain ontologies could be used to provide a service/user PILLAR models with the basic vocabulary. Consequently the ontology mapping process becomes fundamental during the matching process. Hence, we propose an ontology meta-structure to facilitate the ontology mapping process. PILLAR explicitly captures the semantics of both the service and the user creating a framework for more precise service semantic discovery process.
