Caitlin Trasande (Head of Science Metrics) and Euan Adie (Product Manager; founder of Altmetric) are among the participants giving demos at the Altmetrics 2012 workshop, part of the ACM Web Science Conference in Evanston, Illinois. The event will explore alternate sources, paradigms and tools for measuring scholarly communication and impact online. This workshop is a follow-up to the last year’s “altmetrics11”, and will encourage collaboration and cross-pollination between research and practice, combining academic paper presentations with demos of tools (includingAltmetric) and discussion.
