Here’s some inside baseball: the trends in periodization in history dissertations since the beginning of the American historical profession. A few months ago, Rob Townsend, who until recently kept everyone extremely well informed about professional trends at American Historical Association* sent me the list of all dissertation titles in history the American Historical Association knows about from the last 120 years. (It’s incomplete in some interesting ways, but that’s a topic for another day). It’s textual data. But sometimes the most interesting textual data to analyze quantitatively are the numbers that show up. Using a Bookworm database, I just pulled out from the titles the any years mentioned: that lets us what periods of the past historians have been the most interested in, and what sort of periods they’ve described..
More access to the connections between words makes it possible to separate word-use from language. This is one of the reasons that we need access to analyzed texts to do any real digital history. I’m thinking through ways to use patterns of correlations across books as a way to start thinking about how connections between words and concepts change over time, just as word count data can tell us something (fuzzy, but something) about the general prominence of a term. This post is about how the search algorithm I’ve been working with can help improve this sort of search. I’ll get back to evolution (which I talked about in my post introducing these correlation charts) in a day or two, but let me start with an even more basic question that illustrates some of the possibilities and limitations of this analysis: What was the Civil War fought about?
So I just looked at patterns of commemoration for a few famous anniversaries. This is, for some people, kind of interesting–how does the publishing industry focus in on certain figures to create news or resurgences of interest in them? I love the way we get excited about the civil war sesquicentennial now, or the Darwin/Lincoln year last year.
I was starting to write about the implicit model of historical change behind loess curves, which I’ll probably post soon, when I started to think some more about a great counterexample to the gradual change I’m looking for: the patterns of commemoration for anniversaries. At anniversaries, as well as news events, I often see big spikes in wordcounts for an event or person.
