In yesterday’s post, I introduced some of the work I’ve been doing with MALLET and provided a list of topics, sparklines, etc. I wanted today to pull some of that data out and see what trends we could find in the database. Many of the topics found had simple little spikes: a single year where the topic was significant, but not part of a broader trend.
