Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.
Alternative metrics or altmetrics are article level metrics that have been used to quantify the attention given to scholarly papers in online fora or social media. In some way it was sought to replace journal level metrics such as the Impact Factor and also to see if early altmetric scores could predict highly cited papers. Early studies, done soon after altmetrics was suggested in 2013, were somewhat prem-ature as the use of social media was not widely prevalent, and their results may no longer be relevant at the present time when use levels have risen significantly. In the past year, 2016, Altmetric.com has tracked over 17 million mentions of 2.7 million different research outputs. Of these, the top 100 most-discussed journal articles of 2016 were presented with details of journals in which the research was published, affiliations of authors, fields, countries, etc. ..Our attempt is to obtain a bibliometric profile of these papers with high altmetric scores, to see the underly-ing patterns and characteristics that motivate high public attention. In parallel we have analyzed top 100 highly cited papers from the same year. Our objective in this empirical study is to examine the similarities and distinguishing features of scientific attention as measured by citations and public attention in online fora.
