Comparative historical sociologists use data to explain complex historical processes as clearly and precisely as possible. From Weber, to Marx, to Tilly, combining quantitative data with qualitative analysis has been a staple of our craft. Current technologies, however, have enabled the use of a much more complex, contextual, and versatile type of data in comparative historical sociology: high dimensional data. High dimensional data is data with a large number of characteristics or attributes, including texts, images, geo-spacial data, administrative data, and/or long-form surveys, among others. This type of data is most usefully mathematically represented as vectors. Just as regression analysis standardized the use of numbers across many fields of social science, I argue that vector space models have the potential to normalize and standardize the use of high dimensional data of all forms across social science. In particular, I argue that vector space models allow comparative historical sociologists to incorporate many different types of historical data (text and images, images and administrative data, images and geo-spatial, etc.) into the same mathematical framework. This framework allows us to model history in a much more complex and thus more accurate way, while, at the same time, maintaining the empirical clarity that low-dimensional data provide. I demonstrate this claim by using three different empirical vector space models from my own research: word vectors to measure claims-making strategies, discursive vectors to measure organizational similarity, and image vectors to measure neighborhood identities. I end with a few words of caution about how to avoid the curse of high dimensions, while emphasizing the great opportunities this mathematical model provides.
