Mendeley, putting data into the hands of researchers

I was invited to give a keynote presentation at the RecSysTEL Workshop (http://bit.ly/b2Bg2J) on 2010/09/30. It presents Mendeley's tools for researchers and data sets that we made available for the dataTEL challenge, designed to provide new large scale data for researcers in recommendation systems. The event was really enjoyable and the participants were excited about Mendeley.
![“All the time we are very
conscious of the huge
challenges that human
society has now – curing
cancer, understanding the
brain for Alzheimer‘s [...].
But a lot of the state of
knowledge of the human race
is sitting in the scientists’
computers, and is currently
not shared […] We need to
get it unlocked so we can
tackle those huge problems.“](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
