An extensive literature research in the fields of IT and business science reveals that service-related terms as service and e-service have multiple interpretations within business science, information science and computer science, resulting in confusion. These three communities take part in the multidisciplinary process of realizing e-Commerce scenarios for services. Each community has its own role in e-service offering, and uses its own terminology. In this paper we analyze the different perspectives that these three communities have on the online service provisioning concept. We introduce different meanings of service-related terms in the three communities, and use a real-world case study to show how all three perspectives and terminologies need to be joined with each other for the realization of collaborative e-Commerce scenarios for service offerings on the Semantic Web.
