Towards a Social Network Based Approach for Services Composition

With the emergence of Web 2.0 and the related technologies, composing services has left the traditional frontiers of enterprises. In fact, end-users need to use a certain kind of composition in different situations since Web 2.0 has brought a set of technologies making it easy to create or collaborate on new services or use others´ services, e.g., mashups. On the other hand, users participate in different communities and social networks to share common interests and find expertise offered by others. Even if Web services composition tools like mashups include a community dimension helping the service creation process (tagging, rating, ...), they completely ignore this social dimension at the composition level. Our approach is to bring the generated knowledge from interactions between users and services (and by extension from social environments) to enhance services composition. This paper reviews some related concepts and work and then introduces a first view of our framework, named Social Composer (SoCo), aiming at handling this issue from a social networking perspective. SoCo provides dynamic recommendations for services discovery and selection based on the users´ interactions and a social network implicitly built from the interactions between users and services, and the different services compositions operated in the user´s social network as well as the global social network.
