Query: Analysing user identity via time-sensitive semantic edit distance
  (t-SED): A case study of Russian trolls on Twitter   In the digital era, individuals are increasingly profiled and grouped based
on the traces they leave behind in online social networks such as Twitter and
Facebook. In this paper, we develop and evaluate a novel text analysis approach
for studying user identity and social roles by redefining identity as a
sequence of timestamped items (e.g. tweet texts). We operationalise this idea
by developing a novel text distance metric, the time-sensitive semantic edit
distance (t-SED), which accounts for the temporal context across multiple
traces. To evaluate this method we undertake a case study of Russian
online-troll activity within US political discourse. The novel metric allows us
to classify the social roles of trolls based on their traces, in this case
tweets, into one of the predefined categories left-leaning, right-leaning, and
news feed. We show the effectiveness of the t-SED metric to measure the
similarities between tweets while accounting for the temporal context, and we
use novel data visualisation techniques and qualitative analysis to uncover new
empirical insights into Russian troll activity that have not been identified in
previous work. Additionally, we highlight a connection with the field of
Actor-Network Theory and the related hypotheses of Gabriel Tarde, and we
discuss how social sequence analysis using t-SED may provide new avenues for
tackling a longstanding problem in social theory: how to analyse society
without separating reality into micro versus macro levels.
