I think its really a matter of how Walter was built. I mean, if it already has all the facts organized into different subjects, then it wouldn't be hard for a program to manage all the Jepoardy questions. If, on the other hand, it only had pages from different encyclopedias which it had to scan for, and then sort out what pieces to collect, it might be quite a bit harder. I dunno... I still think its being over-hyped a bit. This post is from -- http://socoder.net/index.php?topic=2216
