Trust

Trust is a complex philosophical, social and technical notion, but it underlies many of our digital interactions including e-commerce and collective intelligence. In this lecture we will look at how different disciplines, including Psychology, Sociology and Economics have come to understand Trust through the lens of their own studies, aims and goals, and will explore how computer scientists and software engineers have implemented trust models based on policy, provenance and reputation. We will take a closer look at both Global and Local reputation-based trust, and see how assumptions of transitivity and asymmetry are useful. Finally we will explore trust issues around the largest known store of human knowledge: the Wikipedia

How The Web Devalues Creativity

By lowering the barriers to communication, the Web has not made it possible for writers to make more money; instead large corporate aggregators are taking advantage of creators to make themselves rich. MaryAnn Johanson is the creator of one of the oldest independent film review sites on the web (flickfilosopher.com). In this lecture she addresses the problems of the long tail for the long tailees. How can a creative professional make a living through the Web, when all the power is held by the aggregators? So much for radical disintermediation... This share contains the lecture slides (see slide #29-30 for the summary of her argument), the lecture audio, further reading, a link to her web site and a critique of The Longer Tail from students at another Web Science Trust Network lab.
