Call for Proposals: altmetrics12: tracking scholarly impact on the social Web. An ACM Web Science Conference 2012 Workshop Evanston, IL • 21 June 2011 Increasing scholarly use of Web2.0 tools like CiteULike, Mendeley, Twitter, and blog-style article commenting presents an opportunity to track scholarly impact in novel ways. Metrics based on this diverse set of Web sources could yield broader, richer, and more timely assessments of current and potential scholarly impact. Realizing this, many authors have begun to investigate these altmetrics. altmetrics12 encourages continued investigation into the the properties of these metrics: their validity, their potential value and flaws, and their relationship to established measures. Submissions are invited from a variety of areas: * New metrics based on social media * Tracking science communication on the Web * Relation between traditional metrics and altmetrics * Peer-review and altmetrics * Tools for gathering, analyzing, disseminating altmetrics This workshop is a follow-up to the successful altmetrics11 workshop hosted by WebSci’11. Important Dates 2-page abstracts due: May 18, 2012 Acceptance and abstract publication: May 22, 2012 Open pre-workshop discussion: May 22 – June 18, 2012 Workshop at WebSci 12 June 21, 2012 Discussion closed June 30, 2012 Invitations for post-workshop proceedings TBA Submissions Prospective authors should submit 2-page extended abstracts (max. 1000 words, not including references) via EasyChair. If necessary, the workshop organizers will select the most relevant, original, and significant abstracts for presentation. Experimental results will be given preference, followed by technical reports on working altmetrics tools and position papers. All selected submissions will be published online for open peer review and discussion. Authors are encouraged to participate in the discussions of their work. Based on the presentations and online discussion, selected authors may be asked to submit full papers for peer-reviewed proceedings. Location The workshop is hosted by the ACM Web Science Conference 2012 (Evanston, Illinois). This interdisciplinary conference focuses on advances in studying the full range of social-technical relationships on the Web.
