I had no idea what the news article was talking about, but it sounds like topic modeling with a temporal component. Why didn't they put the paper title or algorithm name in the news article? It's frustrating to read something dumbed down enough that you can't even recognize it. Update: I am betting it is this paper - "A Language-based Approach to Measuring Scholarly Impact" http://www.cs.princeton.edu/~blei/papers/GerrishBlei2010.pdf http://www.cs.princeton.edu/~blei/papers/GerrishBlei2010.pdf
