What increases (social) media attention: Research impact, author prominence or title attractiveness?

  1. 1. What increases (social) media attention: Research impact, author prominence or title attractiveness? Olga Zagovora Olga Zagovora, Katrin Weller, Milan Janosov, Claudia Wagner and Isabella Peters 1
  2. 2. Factors affecting Number of citations  “Paper related factors’’  quality of paper  novelty and interest of subject  characteristics of fields and study topics  methodology  document type  study design  characteristics of results and discussion  use of figures and appendix  characteristics of the titles and abstracts  characteristics of references  length of paper  age of paper  early citation and speed of citation  accessibility and visibility of papers  ‘‘Journal related factors’’  journal impact factor  language of journal  scope of journal  form of publication  ‘‘Author(s) related factors’’  number of authors  author’s reputation  author’s academic rank,  author’s productivity  international and national collaboration of authors  authors’ country, gender, age and race  organizational features and funding  self-citations (Social) media mentions  Number of citations  ...  title length (Zahedi & Haustein, 2018)  title amusement level (Subotik & Mukherjee, 2014)  Media popularity of topic 2
  3. 3. What matters for (social) media attention?  # citations  Discipline  Publication year  Affiliation  @rank  Country  @GDP on edu  Collaboration net  @PageRank  Length  # char, # words, #:  Sentiment  Polarity  Subjectivity 3 Research impact Author prominence Title attractiveness
  4. 4. Research Questions  Which features of publications are associated with increased (social) media attention?  RQ1: What are the most effective factors?  RQ2: Which discipline-specific differences exist between those features?  RQ3: Are the same types of publications popular across different media channels? (Social) media attention: Wikipedia, Facebook, News, Twitter; Altmetric score [see also Altmetric.com] 4

  6. 6. Datasets Publications  Multidisciplinary journal; control for disciplines  High impact journals; comparable papers in terms of quality Selected Journals:  PNAS 2004-2017  Nature Communications (NC) 2010-2017 Additional data  Web of Science (as of 07.12.2017)  DOI, Publication year, Title, Full author names, Citation counts  PNAS website  Field of Science  Springer Nature SciGraph Data Explorer  Field of Science  Altmetric.com (till 07.12.2017)  Altmetric score  Wikipedia  Twitter  Facebook  News 6 Discipline (OECD) PNAS NC Agricultural sciences 221 62 Engineering & Technology 1 133 2 482 (Humanities) (0) (35) Medical & Health sciences 12 813 2 649 Natural sciences 27 994 10 410 Social sciences 1 810 245 Total 43 921 15 883
  7. 7. Modified variables  Citation counts normalization by year & discipline  Log transformation by Thelwall (2017); MNLCS  ln(1+𝑥 𝑖) 1 𝑛 𝑗=1 𝑛 ln(1+𝑥 𝑗) , where 𝑥𝑖- citation count and 𝑥𝑗 is from the same discipline and year as 𝑥𝑖.  Altmetric score normalization by year & discipline  Normalized Log-transformed Altmetric Score (NLAS) 7
  8. 8. Regression models Dependent var.  Media attention metrics:  Altmetric score, log- transformed normed (NLAS)  # Wikipedia articles  # News stories  # tweets  # Facebook posts Independent var.  Research impact  Citations counts, log- transformed normed (MNLCS)  Year of publication  Author prominence  First author PageRank  Last author PageRank  Title attractiveness  Length  Title chunks “:”  Sentiment:  Polarity  Subjectivity 8
  9. 9. Research impact MNLCS  Higher impact papers 1. 2. 3. 4. Recency 9
