Nowadays, organizations are integrating human-computer interaction (HCI) into their information systems. This trend resulted in gathering developers and end-users in different tasks, particularly, the interactive Web services composition (WSC) task. Indeed, to search for solutions that go beyond their individual limited views, an increasing demand of collaboration among users has emerged. However, they are still facing uncomfortable situations especially when they are invited to select the appropriate Web service among functionally similar ones. More support is then needed to provide an effective composition. In this regard, a group recommender system providing the required functionality while considering the users’ preferences, might be highly useful. In this paper, we present a holistic process spanning from capturing users requirements, constructing a global goal model “ColMAP” reflecting their intentions to performing a collaborative, interactive WSC. A step-by-step example illustrates the proposed process. We expect that this approach will pave the way for interactively, collaboratively engineered information systems.
