چکیده انگلیسی:
In recent years, the problem of unreliable content in social networks has become a major threat, with a
proven real-world impact in events like elections and pandemics, undermining democracy and trust in science,
respectively. Research in this domain has focused not only on the content but also on the accounts that
propagate it, with the bot detection task having been thoroughly studied. However, not all bot accounts work
as unreliable content spreaders (p.e. bot for news aggregation), and not all human accounts are necessarily
reliable. In this study, we try to distinguish unreliable from reliable accounts, independently of how they are
operated. In addition, we work towards providing a methodology capable of coping with real-world situations
by introducing the content available (restricting it by volume- and time-based batches) as a parameter of the
methodology. Experiments conducted on a validation set with a different number of tweets per account provide
evidence that our proposed solution produces an increase of up to 20% in performance when compared with
traditional (individual) models and with cross-batch models (which perform better with different batches of
tweets).
