4:00 – 5:00 Invited Talk: Big Data meets Big Social: Social Machines and the Semantic Web, by David De Roure
We are seeing increasing scale of human participation in the digital world, from citizens and scholars alike. At the same time we see increasing computational power and storage: more devices, more processors, more cores (indeed Moore’s Law). An interesting space, generating considerable activity, is where large numbers of people meet large numbers of machines – where new forms of data are produced and also where the new analytics occur, from computational algorithms to citizen science. Underpinning this space is the notion of Social Machines, defined by Tim Berners-Lee as processes in which the people do the creative work and the machine does the administration. The theory and practice of Social Machines are now attracting study, and this talk will discuss this opportunity for Semantic Web approaches to underpin the design and construction of future Social Machines against a backdrop of increasing scale and increasing automation.

David De Roure is Professor of e-Research at University of Oxford and Director of the Oxford e-Research Centre. Throughout his career he has worked closely in and across multiple disciplines to foster innovation in digital methods and scholarship. His current projects range from Web Science (Social Machines and Web Observatories) to Digital Humanities (computational musicology). He has a coordinating role in Digital Humanities at Oxford and is a UK strategic adviser for data resources in social media.
