The next step for Ms. Kotrotsiou is to improve the accuracy of the results through the use of entropic community detection methods, research that is being implemented in collaboration with the professors of the Department of Physics of the Democritus University of Thrace, Stavros Stavrinidis and the Department of Mathematics of the Aristotle University of Thessaloniki, Ioannis Antoniou.
