Query: The altmetric performance of publications authored by Brazilian
  researchers: analysis of CNPq productivity scholarship holders   The present work seeks to analyse the altmetric performance of Brazilian
publications authored by researchers who are productivity scholarship holders
(PQ) of the National Council of Scientific and Technological Development
(CNPq). It was considered, within the scope of this research, the PQs in
activity in October, 2017 (n = 14.609). The scientific production registered on
Lattes was collected via GetLattesData and filtered by articles from academic
journals published between 2016 and October 2017 that hold the Digital Object
Identifier (n = 99064). The online attention data are analysed according to
their distribution by density and variation; language of the publication and
field of knowledge; and by average performance of the type of source that has
provided its altmetric values. The density evidences the long tail behavior of
the variable, with most part of the articles with altmetrics score = 0, while
few articles have a high index. The average of the online attention indicates a
better performance of articles written in English and belonging to the Health
and Biological Sciences field of knowledge. As for the sources, there was a
good performance from Mendeley, followed by Twitter and a low coverage from
Facebook
