Hi @jeason15! Thanks for your interest in textmineR. There's a pretty extensive discussion on this in a closed issue, #35. I've also described it in one of the vignettes https://github.com/TommyJones/textmineR/blob/master/vignettes/c_topic_modeling.Rmd
The TL;DR is that this is a metric of my own making. But it is very similar to the "difference measure" described on page 2 here: https://pdfs.semanticscholar.org/03a0/62fdcd13c9287a2d4e1d6d057fd2e083281c.pdf
Hope that helps! Closing now. But feel free to ask follow up questions in the thread if need be.
Hi! Is there any way that you can point me to documentation regarding the algorithm used to calculate the coherence scores for the topics generated? I am unclear as to which method is being used to obtain this (UCI, UMass, etc). Thanks!
