One of the best studied property of real world networks is their community structure, which represents their composition of dense subnetworks. They can be overlapping [1], hierarchical [2] and temporal [3]. In human social networks all of these properties come into play [4] and can be found on different levels.
On Internet platforms content is posted and within that, trends can be captured as communities of linked topics. They behave highly dynamical, they are born, merge, split or grow and shrink, so capturing them required new methods for temporal community analysis.
Such clusters of topics can move and spread rapidly on social networks. Since these movements depend strongly on the underlying topology, we created multilayer networks, which link contents to users and uncover their relations and interplay.
