In the process of revising chapter 9, my attention returned to a very interesting free software that I found many months ago. This one has helped me quite a bit in ways I will describe with as much detail as I can manage at 12:37 am.
One of the things that can drag down writing quality is excessive unintended repetition of phrases. As an example, your natural unrevised writing style may involve "of the" way too often. What I'm talking about here is when multiple instances of "of the" appear too closely together for comfort. This sort of dangerous repitition happens more often than you might think, and the antconc program is an excellent tool for tracking this down.
I will now provide a screenshot of one useful function it serves. In this example, I am analyzing David Gonterman's Blood and Metal Alpha chapter 1, because he is a marvel in the field of authoring.
What you see above is a collection of two word phrases that occur in the text more than four times. It's no surprise that Davey Crockett appears in second place. The lesson is clear: David Gonterman is so obsessed with his talentless mary sue self-insert character that it takes precedence over most of the English language.
Gonterhate aside, the "N-Grams" listing as well as the "Concordance Plot" provide an excellent analysis of what phrases you might be writing too frequently. The program can do some other related things as well, so I definitely recommend it to writers and those who are simply curious.
