This must be the CYC project at MCC, Austin Texas. It is described in a recent book, "Building Large Knowledge-Based Systems, Douglas B. Lenat and R.V.Guha, Addison-Wesly, 1990. The CYC data base is composed of frames, called "units", which can have all sorts of other data structures and procedures attached to thm -- including many kinds of inference-making and reasoning-by-analogy mechanisms. The system is too large to summarize, and is still lacking in many types of commonsense knowledge, so it is hard to evaluate at this point. But it appears to be the only such project ever attempted. (That is, since Aristotle's project.)
