  The last decade of altmetrics research has demonstrated that altmetrics have
a low to moderate correlation with citations, depending on the platform and the
discipline, among other factors. Most past studies used academic works as their
unit of analysis to determine whether the attention they received on Twitter
was a good predictor of academic engagement. Our work revisits the relationship
between tweets and citations where the tweet itself is the unit of analysis,
and the question is to determine if, at the individual level, the act of
tweeting an academic work can shed light on the likelihood of the act of citing
that same work. We model this relationship by considering the research activity
of the tweeter and its relationship to the tweeted work. Results show that
tweeters are more likely to cite works affiliated with their same institution,
works published in journals in which they also have published, and works in
which they hold authorship. It finds that the older the academic age of a
tweeter the less likely they are to cite what they tweet, though there is a
positive relationship between citations and the number of works they have
published and references they have accumulated over time.
