Temporal Alignment of Reddit Network Embeddings

Motivated by the concepts and findings being developed for diachronic word embeddings, in this paper, we explore how the application of the same principles can be leveraged to study structural roles from a temporal perspective. In the same way words with a similar meaning will repetitively appear in the same contexts, structural roles in graphs are also defined by the topological company that they keep. However, structurally equivalent roles may or may not occur in close proximity within a graph. Our goal is to map the participants of the popular social media website Reddit1, into an embedding space that best represents the similarity of the structural roles that they occupy and to then measure how their roles change over time.
