I'm working through the O'Reilly _Programming Collective Intelligence_ (http://www.librarything.com/work/3151375) and I thought it might be interesting to see if a neural network of LibraryThing tags could sort books into fiction/non-fiction buckets, using books with Deweys as a training set. Has anyone done anything like this? Does anyone have a potential reading list? Does anyone want this idea—using LT's tags?
