Jobs cluster into six groups (colour), connected by ‘topics’ (largest nodes)

Here is a zoomable pdf of the same image, for clarity

In this case, the two mode network of jobs to top consituent topics provides much more clarity than the graph I posted at the end of part 2, the one-mode jobs-to-jobs via shared topics. I used the java gui for MALLET, which arranges the output in a very nice hyperlinked folder, which you may explore here. You can grab the CSV and the Gephi files from this directory.
