  • http://www.niso.org/news/events/2013/webinars/altmetrics NISO Webinar: New Perspectives on Assessment How Altmetrics Measure Scholarly Impact November 13, 2013 Speakers: Euan Adie - Founder, altmetric.com Stefanie Haustein, Ph.D. - Research Analyst at Science-Metrix Mike Taylor - Research Specialist, Elsevier Labs
  • Beyond traditional impact: what can altmetrics do for you? Euan Adie, altmetric.com NISO webinar, 13th November 2013
  • Several  different  tools   available  
  • What are “altmetrics”? o  “alternative metrics” o  new ways of measuring different, non-traditional forms of impact, potentially of non-traditional outputs. o  “alternative to only using citations”, not “alternative to citations”. o  complementary to traditional citation-based analysis.
  • Every researcher is a communicator Within academia Presentations and seminars Funding and ethics applications Academic books Journal articles and posters Term papers and essays Meetings and conferences Correspondence Within society Speaking at public events Books for general audiences Press Social media Blogs Policy documents We should measure both
  • New perspectives of impact SOCIETAL IMPACT ACADEMIC IMPACT Journal Impact Factor Citation counts Traditional metrics + Download counts Page views Mentions in news reports Mentions in social media Mentions in blogs Reference manager readers … etc. Alternative metrics “altmetrics”
  • One available tool. We are used a lot by publishers, now some institutions too. We serve ± 2.5 million requests a day.
  • Where are the readers? Who are the readers?
  • What’s  interes3ng  about  this   kind  of  data?  
  • Altmetrics  tools  are  at  version  0.1  
  • Altmetrics  tools  don’t  (yet)   provide  good  metrics  for   impact     BUT     They  can  help  you  find   evidence  of  impact,  successes  
  • Evidence of public outreach? An article on the ecological impacts of the Fukushima nuclear accident. •  > 1,859 twitter accounts shared, combined follower count of 2.5M. •  68% of tweets sent from Japan. Figure 1 •  77% of tweets from members of the public. 2012, Scientific Reports 2, 570
  • A different example, from the USP
  • Evidence research has reached patients?
  • PLOS  ALM  Reports:  An  exploratory  review   Engagement/Influence  beyond  citaEons  
  • PLOS  ALM  Reports:  An  exploratory  review   Engagement/Influence  beyond  citaEons   q  No  cita3ons  in  3  months  since   publica3on.   q  However  TwiJer  men3ons  70x  the   average  ar3cle  in  our  dataset.   q   4x  the  average  for  PLOS  Medicine   ar3cles  in  2013.      
  • Engagement/Influence  beyond  citaEons   MEP     Centre  for  Bioethics     MEP     Professor  of  EBM     Journal  editor     Health  journalist     NGO     Health,  PopulaEon  &   NutriEon  @  The  World   Bank      
  • Monitoring  progress:  WT’s  key  indicators   Outcomes   Key  indicators  of  progress   Discoveries       1.  2.  significant  advances  in  the  genera3on  of  new  knowledge   contribute  to  discoveries  with  tangible  impacts  on  health   ApplicaEons         Engagement     3.  contribute  to  the  development  of  enabling  technologies,  products   and  devices   uptake  of  research  into  policy  and  prac3ce         Research  leaders       Research   environment           Influence   4.  5.  6.  7.  8.  enhanced  level  of  informed  debate  in  biomedicine   significant  engagement  of  key  audiences  &  increased  reach   develop  a  cadre  of  research  leaders   evidence  of  significant  career  progression  among  those  we  support   10.  key  contribu3ons  to  the  crea3on,  development  and  maintenance  of   major  research  resources   contribu3ons  to  the  growth  of  centres  of  excellence   11.  12.  significant  impact  on  science  funding  &  policy  developments   significant  impact  on  global  research  priori3es  and  processes     9. 
  • Quan3fying  aJen3on   Altmetric score
  • Note  that  we  can  measure   aJen3on,  but…     Posi3ve?    Nega3ve?   For  scien3fic  reasons?   Or  because  the  3tle  is  funny?   Is  364  good  or  bad  anyway?    
  • Context is everything
  • In general, altmetrics numbers… X Don’t represent the quality of research. X Don’t indicate the quality of individual researchers. X Don’t tell the whole story – always look for qualitative data as well
  • Why  score  at  all?  To  allow  ranking  
  • What  should  we  be  measuring   beyond  aJen3on?   Ques3on  for  the  academic   community.  
  • Problems  
  • Problems     •  30  –  40%  of  recent  biomedical   papers  will  have  Altmetric   aJen3on.  But  <  10%  in  social   sciences.  
  • Problems     •  30  –  40%  of  recent  biomedical   papers  will  have  Altmetric   aJen3on.  But  <  10%  in  social   sciences.   •  Tools  have  subtle  bias:  data   sources  are  mainly  those  popular   in  US,  Europe

  • Disciplinary differences and other biases Exploring social media metrics in scholarly context Stefanie Haustein stefanie.haustein@umontreal.ca @stefhaustein
  • Overview •  Altmetrics: definitions •  Bibliometrics: in retrospect •  Altmetrics: present •  correlations •  publication age biases •  disciplinary biases •  subject biases •  Altmetrics: future •  References
  • Altmetrics: definitions •  term coined by Jason Priem •  introduced as a better filter than and alternative to citations and peer-review http://altmetrics.org/manifesto/ •  “…altmetrics is a good idea, but a bad name” “…we would like to propose the term influmetrics” Rousseau & Ye (2013) •  rather complementary than •  alternative to citations social media metrics
  • Altmetrics: definitions •  ultimate goals •  similar to but more timely than citations Ø  predicting scientific impact •  different, broader impact than captured by citations Ø  measuring societal impact •  impact of various outputs Ø  “value all research products” Piwowar (2013)
  • Altmetrics: definitions •  Altmetrics are “representing very different things” (Lin & Fenner, 2013) •  unclear what exactly they measure: •  •  •  •  scientific impact social impact “buzz” all of the above?
  • Altmetrics: definitions ad-hoc classifications need to be supported by research
  • Altmetrics: definitions scientist on Twitter tweeting scientific paper in non-scholarly manner: •  scientific impact? •  social impact? •  buzz?
  • Altmetrics: definitions •  complex to define and classify tools and motivations •  scientific and non-scientific audiences cannot be determined on the platform used •  level of engagement differs not only between platforms but also within: saving paper to Mendeley library vs. tweeting about it saving vs. reading retweeting link vs. discussing content Ø  differentiation between audiences and engagement needed to determine meaning of metrics
  • Bibliometrics: in retrospect •  when Garfield created SCI, sociologists of science analyzed meaning of publications and citations (Merton, Zuckerman, Cole & Cole, etc.) •  sociological research •  What is it to publish a paper? •  What are the reasons to cite? •  empirical bibliometric research •  disciplinary differences in publication and citation behavior •  delay and obsolescence patterns
  • Bibliometrics: in retrospect •  empirical studies helped sociologists to understand structure and norms of science •  for bibliometricians, studies provided a theoretical framework and legitimation to use citation analysis in research evaluation •  knowledge about disciplinary differences and obsolescence patterns helped to normalize statistics and create more appropriate indicators
  • Bibliometrics: in retrospect •  similar to development of SCI in the 1960s, social media metrics have to be analyzed: •  qualitative studies to analyze who, how and why people use various social media platforms •  large-scale quantitative studies to determine differences and biases in terms of disciplines, topics, document types, publications years, publication types and sources, author age and affiliation, etc. Ø  to find out what various social media metrics mean and what they can be used for
  • Altmetrics: correlations e.g., Mendeley •  793 Nature papers: ρ=0.559 •  •  •  •  •  •  •  Li, Thelwall, & Giustini (2012) 820 Science papers: ρ=0.540 1,651 JASIST papers: ρ=0.458 Bar-Ilan (2012) 5,596 PLoS ONE papers: ρ=0.3 Priem, Piwowar, & Hemminger (2012) 1,136 bibliometrics papers: ρ=0.448 Bar-Ilan et al. (2011) 1,389 F1000 papers: ρ=0.686 Li, & Thelwall (2012) 62,647 social science papers: ρ=0.516 Mohammadi & Thelwall (in press) 14,640 humanities papers: ρ=0.428 random sample of Zahedi, Costas, & Wouters (2013) 200,000 WoS papers: ρ=0.35 586,600 PubMed papers: ρ=0.386 Haustein, et al.(submitted)

  • Altmetrics: disciplinary biases x-axis: coverage of specialty on platform y-axis: correlation between social media counts and citations bubble size: intensity of use based on mean social media count rate
  • Altmetrics: subject bias General Biomedical Research papers 2011 Scatterplot of number of citations and number of tweets (A, ρ=0.181**) and Mendeley readers (B, ρ=0.677**), bubble size represents number of Mendeley readers (A) and tweets (B). The respective three most tweeted (A) and read (B) papers are labeled showing the first author.

  • Altmetrics: future •  before applying social media counts in information retrieval and research evaluation, we need: Ø  to understand and define meaning of various social media metrics Ø  to identify different biases Ø  to differentiate between audiences and level of engagement Ø  more transparency and reliability in data aggregation
