Web 2.0 is envisioned as an open garden for services and it puts people into the centre of the vision. The success of the user generated content raises the new idea of enabling end-users to create their own services. The first contribution of the thesis is to provide a comprehensive survey of the state-of-the-art development in this area. We give the specific description of UGS, and then go through different technologies to analyze their challenges. Our second contribution lies in designing and implementing a simple mashup platform which provides the greater motivation for mashups usage. We present a consumer mashup framework based on daily activities, by relating every-day calendar events to useful gadgets. The system, named EBSP, was evaluated by 131 end-users to test for its usability. Also, as a representative example, the system is used in a proposed user-acceptance model for consumer mashups. Our third contribution focuses on the problem of using social annotation to support web widget discovery. An enhanced web gadget discovery model is proposed based on social tagging. Using the online service Widgetbox.com, we demonstrate the accuracy and efficiency of our proposed model. Fourthly, we designed a novel system for activity-oriented online social networking named Dig-Event. Dig-Event provides an open, social space for users to share events and discover the activities of mutual interests among social contacts. It allows users to share their activities, to customize their social circles, to conduct events, and to socialize around them. The features of event recommendation and integration with existing social networks further boost the event socializing experience
