topic modeling, literature review, co-occurrence networks

Conducting a literature review requires you to read and synthesize a large number of articles. This can be rather time consuming. It is also difficult to keep the articles in your head while synthesizing them into your review. Using topic modeling as part of your literature review can provide you with a quick overview of the articles and the topics they discuss. In this talk that I gave at Networks 2021 I tackle the issue of interpreting topic models. I introduce two approaches: topic co-occurrence networks and keyword co-occurrence networks. The former provides an overview of the connections between the topics and how they can be grouped into clusters. The latter allows you to explore an individual topic in more detail by visualizing the connections between the most common keywords associated with this topic.
