What does "analytic philosophy" look like to a computer?

Jonathan Strassfeld, an intellectual historian completing a PhD at the University of Rochester on the history of American philosophy, is seeking help with research for his dissertation that involves using text mining to examine the development of analytic philosophy in the mid-twentieth century. Part of the work calls for using a classification algorithm to identify analytic and non-analytic texts. To do this, one must  'train' the computer what analytic philosophy looks like by giving it a sample of of representative texts. Jonathan would like to put the question to the readers: what works should be included in a list of texts meant to exemplify philosophical analysis? He requests you restrict suggestions to journal articles published between 1930-1980.
