Table 4 Topic Categorization based on Distinct Prevalence and Centrality

From: Evaluating latent content within unstructured text: an analytical methodology based on a temporal network of associated topics

Low degree and low prevalence (N = 4)
 Given these topics are under-researched, they present opportunity to extend the body of knowledge within the field through further study
Credit, Loans, Debt & Repayment (low PageRank)
Data Security (low PageRank)
Sport Consumption & Gamification (low PageRank)
