Big-swsdm: Bipartite graph based social web service discovery model

Abstract

With the increasing number of similar web services nowadays, the need to satisfy the complex user requirements and locate relevant services remain necessary. As a complex and challenging task, many approaches have been proposed. Nevertheless, they totally neglect the contribution of the social dimension. The mix of two domains social computing with service oriented computing opens the door to new discovery schemes. It gives birth to a new notion Social Web Services. In fact, integrating the social aspect into web services can benefit them to become active entities that can collaborate, compete or substitute each other. In this paper, we present the second step of our social web service discovery model that operates on a bipartite graph with user-user, user-service and service-service relationships and employs new metrics to evaluate the ability of a user to help the service requester to satisfy his needs.
