"Aiming to Learn as We Do, A Machine Teaches Itself"
The machine mentioned in this article (New York Times, Oct 4, 2010) is, of course, a computer, and it is designed to teach itself semantics by trolling the Internet, primed with a few basic linguistic categories. To this non-expert, it looks inventive and promising. I'd like to see someone pursue a similar project to enable a computer to teach itself how to make moral judgments.
One problem with using the Internet is the heavy emphasis on pornography and celebrities. Perhaps there's a way to adjust for that.
