Since the early 1990's, the Cornell CS department has developed one of the leading AI groups in the world, as can be seen by our record of awards, press mentions, and other recognition. Yet, our relatively small size makes for a collaborative and cooperative environment within which a broad set of research groups flourish. 

As of November 2017, lists Cornell as #2 in the area (over five subareas) of AI.
