Introduction: altmetrics• alternative use and visibility of publications
on social media:
more traditional forms of use:
• alternative forms of research output
“study and use of scholarly impact measures based on activity in online tools and environments”
“a good idea but a bad name”

Introduction: bibliometrics
Introduction: altmetrics
Background• social media activity around scholarly articles grows
5% to 10% per month
• Mendeley and Twitter largest sources for mentions of scholarly documents
• Twitter• used by ca. 10% of researchers in a professional context
• 22% of Web of Science journal papers published in 2012
• number of tweets per paper highly skewed
• low correlations with citations
• popularity of humorous and curious topics
• automated diffusion of scientific papers on Twitter

Research questions and objectives
• What information about tweeting behavior can be used to distinguish different kinds of Twitter impact of journal articles?
• Who is diffusing scientific journal articles on Twitter?
• What user groups can be distinguished:• regarding engagement with papers and• potential reach and audiences of users?
• How does the tweeting behavior of these user groups differ?
Research questions and objectives• distinguishing between:
exposure = number of followersengagement = dissimilarity between tweet and paper title
Methods• 660,149 original tweets (Altmetric.com up to June 2014)
• 237,222 tweeted documents (WoS 2012 with DOI)
• 125,083 unique users• number of tweets to 2012 papers
• mean tweets per day (all tweets up to April 2015)
• mean relative citation rate of tweeted papers
• mean engagement (dissimilarity between tweet and paper title)
• mean exposure (mean number of followers during tweet)
• mean number of followers (April 2015)
• mean number of following (April 2015)
• tweeted document coupling user network
