  • 3. Do retweets skew the data or emphasize existing trends? Would original tweets give more accurate information about the visibility, awareness, and impact of research? Should retweets be filtered out when conducting altmetric research?
  • 4. This pilot study aims at contributing to this discussion by analyzing the impact of retweeting on the frequencies with which scientific articles from Nature, Science, and PLoS ONE were mentioned on Twitter.
  • 5. Top 10 Nature titles (when including retweets) n Top 10 Nature titles (when excluding retweets) n Death of evidence 167 Approaching a state shift in Earth’s biosphere 87 Approaching a state shift in Earth’s biosphere 89 The biological impacts of the Fukushima nuclear accident on the pale grass blue butterfly 79 The biological impacts of the Fukushima nuclear accident on the pale grass blue butterfly 86 Death of evidence 67 Measuring the Evolution of Contemporary Western Popular Music 72 Measuring the Evolution of Contemporary Western Popular Music 64 A 61-million-person experiment in social influence and political mobilization 58 A 61-million-person experiment in social influence and political mobilization 50 (survey, already closed) 43 The polarizing impact of science literacy and numeracy on perceived climate change risks 36 Must try harder 39 Must try harder 32 Structure, function and diversity of the healthy human microbiome 37 Structure, function and diversity of the healthy human microbiome 32 The polarizing impact of science literacy and numeracy on perceived climate change risks 37 If only ... 32 A different agenda 36 The tomato genome sequence provides insights into fleshy fruit evolution 27 Table 1. The 10 most frequently tweeted articles in Nature, including retweets and excluding retweets.
  • 6. PLoS ONE (titles) Including retweets total: 38152 unique: 11490 Excluding retweets total: 31788 unique: 10885 Spearman rank correlation: 0.913 (between the frequencies with which articles were mentioned when including and excluding retweets)
  • 7. Nature (URLs) Including retweets total: 8554 unique: 2365 Excluding retweets total: 7028 unique: 2357 Spearman rank correlation: 0.927 (between the frequencies with which articles were mentioned when including and excluding retweets)
  • 8. Science (titles) Including retweets total: 6038 unique: 2040 Excluding retweets total: 2756 unique: 1466 Spearman rank correlation: 0.745 (between the frequencies with which articles were mentioned when including and excluding retweets)
  • 9. CONCLUSIONS The results here can only be taken as indicative of the situation of these specific journals. In order to gain a more comprehensive understanding of the possible impact retweeting may or may not have on altmetrics the analysis should be repeated on a larger dataset with URLs to articles in a wider selection of scientific journals.
