I applaud the efforts of the folks at UC Irvine in the area of text mining and believe it's vital for reserach to continue in this area, but this press release does make it seem that they've uncovered something new. According to the release:
"The demonstration is significant because it is one of the earliest showing
that an extremely efficient, yet very complicated, technology called text mining
is on the brink of becoming a tool useful to more than highly trained computer
programmers and homeland security experts."
I would have to argue that folks in the business world have already established text mining as a useful tool. (Hopefully Homeland Security isn't just learning about it!)
