Berkman Center for Internet & Society at Harvard University has released the video of the presentation, Lee Dirks on Transforming Scholarly Communication. From the description:
Lee Dirks, Director of Education & Scholarly Communications in Microsoft's External Research division proposes a vision for the future of research and the need for semantic-oriented computing by exploring eResearch projects that have successfully applied relevant technologies. He suggests that a software + service model with scientific services delivered from the cloud will become an increasingly accepted model for research.
The presentation is also available as a podcast.
P.S.: There are notes of the presentation on EtherPad.
