Query: Tracking the Twitter attention around the research efforts on the
  COVID-19 pandemic   The outbreak of the COVID-19 pandemic has been accompanied by a bulk of
scientific research and related Twitter discussions. To unravel the public
concerns about the COVID-19 crisis reflected in the science-based Twitter
conversations, this study tracked the Twitter attention around the COVID-19
research efforts during the first three months of 2020. On the basis of nearly
1.4 million Twitter mentions of 6,162 COVID-19-related scientific publications,
we investigated the temporal tweeting dynamic and the Twitter users involved in
the online discussions around COVID-19-related research. The results show that
the quantity of Twitter mentions of COVID-19-related publications was on
rising. Scholarly-oriented Twitter users played an influential role in
disseminating research outputs on COVID-19, with their tweets being frequently
retweeted. Over time, a change in the focus of the Twitter discussions can be
observed, from the initial attention to virological and clinical research to
more practical topics, such as the potential treatments, the countermeasures by
the governments, the healthcare measures, and the influences on the economy and
society, in more recent times.
