  1. 1. Altmetrics Judit Bar-Ilan Department of Information Science Bar-Ilan University, Israel
  2. 2. Scientific revolution in scientometrics? • Taxonomic change: not only impact on science, but also on society (Bornmann, 2013) • “altmetrics will play a significant role in measuring societal impact”(Bornmann, 2013 in the SIGMETRICS list) • Scientific revolution or not, bibliometricians start to take altmetrics into account – Altmetric indicators can measure (at least partially) societal impact
  3. 3. Altmetrics – recent achievements • Altmetric tools – ImpactStory, Altmetric, Plum Analytics • Publishers add altmetrics to their site – PLoS ALM, BMJ • Post-publication peer-review – F1000, PubMed, ResearchBlogging • Studies showing the value of Mendeley readership counts – Significant, medium strength correlations with citation counts – Seems to be one of the most promising altmetric indicators
  4. 4. Achievements + Interest -> Responsibility • • • • What to measure? What is the meaning of the measurements? How to measure? What is the quality of the underlying data?
  5. 5. What & how to measure? • Usage – Multiple copies • Popularity – Tweets are ephemeral – Shares • Discussions – Sentiments – Different venues • Not only scholarly peer-reviewed publications – Books, reports, datasets, applications, software, presentations, videos, ….
  6. 6. What is the meaning of these measures? • Why do users download an article? How are “views” related to “downloads”? • Why do they share a link? • Why do they make use of a dataset? • Who are the users? • … • Note – Quite easy to “game” the measures – No gatekeepers – The “wisdom of crowds”
  7. 7. Data sources • Twitter – “Big data” – Feeds are not comprehensive – Difficult to monitor – Even more problematic to reach “historical data” – Tweets archived at the Library of Congress
  8. 8. Reference managers • Are they here to stay? – Connotea, 2collab – Most popular today: • Mendeley, CiteULike • Zotero – data are not aggregated • Is altmetric analysis high on their list of priorites? • Data quality – Entered by users • Accuracy, multiple records – Author names
  9. 9. There is a lot to be done ! Good luck!!!
