TowardsWeb User-Centric Development

World Wide Web (WWW) has become the greatest repository of information that man has ever assembled and it is continuously growing. WWW transformed itself into a generative environment that fosters innovation through the advance of technologies and a shift in people’s perception of the Weband how they use it. The new WWW or Future Internet is that of an Internet of Services and Internet of Things.Naturally, a series of questions arise from this context: how do you filter things to create more value than you currently get? how do you aggregate things in an intelligent and easy way instead of doing it in your head? The world cannot be described unambiguously, so how can you allow users to deal with the world in their own way, based on their understanding? Levine in his book "Cluetrain manifesto" was arguing that markets are conversations so how can users be involved in the conversation? how can users be empowered with easy consumption of the services, information, things that they found around?However design and deployment of such software capable of direct interaction and empowerment of the end-user is still an issue. We have on one side users that have ideas, but do not have technical background and lack programming skills to do the development by themselves. On the other side, we have large amounts of data, resources and services that could be aggregated both in terms of data, but most important in terms of behavior to innovate and create new things.Our goal in this thesis is to address this lack of tools that are capable of direct interaction andempowerment of end-users, in a unified manner. Thus our main contribution in this thesis is the development of a holistic approach for web based systems that are user-centric and that integrate data, services and behavior available on the Web 2.0.
