The document discusses reflective open community information systems on a web scale. It notes that the web is a fragmented, scale-free network based on trust and passion within communities. It presents paradigms of web science that combine analytic and synthetic approaches. It then outlines several technologies and tools for building responsive open community environments, supporting communities, and performing community analytics. Examples of demos and teaching activities are also provided.

4. Web Science Paradigms
Merge of analytic and synthetic paradigms
In an analytic discipline
TeLLNet
– To find laws
– To generate phenomena
– To explain observed
phenomena
In a synthetic discipline
– To formalize
– To create algorithms Example: The PageRank link structure
