As a follow on to the previous entry, I recently came across the semantic search engine, Cuil.
Did ever so much better than W|A on the search terms I used, and produced a more usable set than did the Goog.
Popped up the right names for reconstructability analysis and edge of chaos, picked up on Wolfram and cellular automata. Got the dates right. Got good stuff on handbells and filk, and even came up with the first use of the term ‘filk’ music. Apparently by Karen and Poul Anderson. I like it.
