The semantics of Web services is often provided by suppliers and embedded as extensions within the service descriptions expressed in WSDL. This type of annotation can be very costly and is generally performed by well-trained cognitive or knowledge engineers. In this research work, we aim at providing an alternative to the actual Semantic Web Service (SWS) technologies by bringing a community-based, crowd-sourced or social semantics into Web services. This semantics is created by users through collaborative tagging on the capabilities of Web services after testing or using them. We argue that this type of semantic annotation can be very pragmatic and facilitate the process of Web service discovery, composition or clustering assisted by users.
