So, the wedding announcements of The New York Times. Call them what you will -- a "mergers and acquisitions" report for the society set, reading fodder for Sunday brunches, a "sports pages for women" -- their official name is misleading: They offer much more than simple announcements of weddings. They offer, actually, nothing short of documentation of a changing society. As women's liberation came along, as society shifted toward a more career-based notion of success, as same-sex relationships gained more and more mass-cultural recognition, the wedding announcements have been there to document all the shifts. The Times, as it were, has been ON IT.

Which is not to say that it's not easy -- very, very easy -- to mock the announcements, what with their "a daughter ofs" and their "was graduated froms" and their Muffies and Buffies and their many, many mentions of Harvard. But the very thing that makes the blurbs fitting objects of mockery -- the formulaic social coding they engage in -- is also the thing that gives them their documentary power. The announcements offer little notes from The New York Times to its readers that say, effectively and fairly explicitly: This is what we value. This is why your marriage is news. This is what makes you matter. The announcements announce, but more to the point they insinuate. They tell you how to succeed in society. Love the "Weddings and Celebrations" or hate them -- or, like many of us, hate-love them, or love-hate them -- those weekly little blurbs function as a de facto index of social transformation.

Which is another way of saying that The New York Times's wedding announcements are also data sets. And the information they contain reveals the assumptions embedded in contemporary notions about love and partnership and social success -- assumptions about who exactly constitutes, as David Brooks famously put it, the nation's "cognitive elite."

I mention all that because this week the engineering team over at Rap Genius, the lyric-annotation service, released WeddingCrunchers.com, a searchable database of nearly 60,000 Times wedding announcements published between 1981 and 2013. Think Google's Ngram Viewer, but for marriages. As Rap Genius explains it: "WeddingCrunchers lets you measure the frequency of specific words and phrases in these announcements. When you search for a phrase (technically called an n-gram), you get back a graph displaying how usage of that phrase fluctuated over time."

Which is amazing. The feature does exactly what Google's Ngram Viewer does for books, transforming prose into data that can, in turn, offer its own kind of insights. So a keyworded search on WeddingCrunchers suggests, for example, the major shifts in marriage age that occurred between the early 1980s and today:

Which is also to say, in gif form:

Another search suggests the transformation David Brooks saw in the wedding announcements -- a shift that finds the write-ups decreasing their emphasis on "birth and breeding," and increasing their emphasis on "education and career."
