Natural Language Processing in the Enterprise

We worked with Stanford on a number of natural language processing oriented problems, including the Talking Mr. Clean effort.    I note that a number of the spin off companies that came from Stanford no longer exist, at least in the same form.  See, for example, the Barbara Hayes-Roth company Extempo, no longer has a web site.  It specialized in training systems, we used it to provide a voice to brand characters.  Does somewhere know where that company went?  Contact me.   I see now that Coursera has a course originating at Stanford on NLP. Worth a look at to understand the state of the technology.  Update:  I have been told that Extempo failed when attempting to get additional funding during the 2000 dotcom bubble.
