UKOLN is organising a one-day workshop entitled “Metrics and Social Web Services: Quantitative Evidence for Their Use and Impact” which will be held at the Open University in Milton Keynes on Monday 11 July 2011. The workshop will explore ways in which metrics related to the use of Social Web services can be employed in order to provide evidence of how the services are being used. It will also allow delegates to make comparisons with their peers as well as enable them to identify trends in usage. Attendance at the workshop is free. Bookings should be made using the online Eventbrite booking system.
