In a couple of weeks the director of the Darpa Information Processing Technology Office, Ron Brachman, is visiting Austin to solicit ideas for new Darpa programs. We hope to spend all day with him addressing our solutions to the problem you refer to above. I have asked for a 45 minute slot to describe my ideas which have been described in this forum. Not to dispute the overall point, I would like to clarify Cycorp's current knowledge entry activity. Up to now we have not actually performed much data entry, rather we have encoded a broad range of commonsense classes (we call Collections) and relatinships (we call predicates) in symbolic logic (which we call CycL). The downside is that Cyc is presently passive and can answer deductive queries about its contents. The upside is that the Cyc commonsense ontology (structure of Collections, Predicates, facts and rules) can be extended into any domain you might want to describe. Experiments have shown that Cyc is at the point where 75% of the high and mid level concepts required for a new domain (for example high school chemistry) already exist. I was able to add vocabulary to represent UML state machines rather easily, for example. We have a team of computational linguists who have added the vocabulary to make Cyc able to represent lexical concepts. In 2003, our data entry activities will be emphasized as a result of our participation in Darpa's Total Information Awarenesss program for which we will construct a Terrorism Knowledge Base, containing all the open-source terrorist individuals, organizations and events that we and our sub-contractor experts can input. It is hoped that the TKB will prove useful, by answering interesting paramertized questions, for US defense and intelligence communities. -Steve -- =========================================================== Stephen L.
