Clearwell Enron 'Topics'

Moving forward with my look at semantic network analysis of the Enron data, I've been exploring Clearwell's 'Topics' feature, which like a lot of Clearwell's features, does much of the work for you with a few clicks.

For your perusal, here is the entire Topics list of the Enron corpus, sorted as Clearwell supplies it, and here are the top 10, sorted by occurrence frequency:

I am interested to more fully know how Clearwell derives these topics, and to compare this process to other tools, like Gensim.
Here is Clearwell's writeup on its 'Topics' analysis process.
I will continue posting updates to this project as it develops.
