Are readers a sink for information??

Project Breadcrumbs :: Álvaro Figueira (PI) :: Presentation at CoLab annual conference :: Fundação Calouste Gulbenkian :: 21.09.2010

Well, ...

Wouldn’t it be nice if we could have access to:• opinions of readers• interests of readers• relations between information they consume• relevancy of parts of news• statistics• sub-communities of readers• trail of the news...

Research questions:

• How to integrate automatic and social classification?

• Is this hybrid model better than the two isolated ones?

• How to use and navigate in a network of fragments?

• How to analyse the network?

• Can we infer implicit links between

– Different articles/events/stories?

– Different readers?

• Can we infer interests of readers and the contribution from their participation?
