Babble demo moved
We have moved the Babble demo from this site to a new site at the Trace Center that allows you to ask Babble questions about TV listings. The TV listing site was developed as part of an NSF grant to explore using Tridbits as a natural language interface to household devices.

In addition to asking what's on TV, you can still converse with Babble on other topics, although its vocabulary remains very limited. Its knowledge of the world consists mostly of TV listings, state capitals and some simple childish facts. You can tell it new information, and then ask it about what you told it. It will only remember new information during the current session. Check out the talking tips at right. Babble has mastered a few more abilities since then, especially in understanding relationships and time, though more work remains.

Babble's out of school
Unlike the demo previously available on this site, the TV listing demo does not allow the user to teach Babble new words. We found this was more than most people want to do. We may reimplement a demo on this site for people who would like to help train Babble. Please email if you are interested in this.
