What's Implicit in Space
This event took place on Tuesday 25 March 2008 at 11:30

 
Prof. Massimo Melucci Department of Information Engineering, University of Padua, Italy

The talk will introduce a geometric model and its investigation in the context of enhanced implicit feedback tailored for each task and personalized for each user. The geometric model leverages recent advances of vector space-based information retrieval. The results of some experiments using rich interaction logs demonstrate both the effectiveness of our proposed algorithm and the potential value of incorporating multiple sources of interaction evidence when developing implicit feedback algorithms.

Social Software is...


Social Software
Social Software can be thought of as "software which extends, or derives added value from, human social behaviour - message boards, musical taste-sharing, photo-sharing, instant messaging, mailing lists, social networking."

Interacting with other people not only forms the core of human social and psychological experience, but also lies at the centre of what makes the internet such a rich, powerful and exciting collection of knowledge media. We are especially interested in what happens when such interactions take place on a very large scale -- not only because we work regularly with tens of thousands of distance learners at the Open University, but also because it is evident that being part of a crowd in real life possesses a certain 'buzz' of its own, and poses a natural challenge. Different nuances emerge in different user contexts, so we choose to investigate the contexts of work, learning and play to better understand the trade-offs involved in designing effective large-scale social software for multiple purposes.
