Carrot2 Clustering Engine

I did extensive research on this thing when I was doing my last start-up. It's a clustering engine, but it is limited in that it is specifically tuned to cluster search results. For example, it returns poor clustering results if you input a set of long text documents; it works much better when its input consists of a query string and a set of titles and short snippets.

Am I the only person that thinks the visualization is the smart part (and wonders why it's not the front page)?

Nothing to do with "Clustering"; it's a multi search-engine result filter, albeit a fancy one.

grrr damn web designers .... I need to READ not to watch nice shadows everywhere!

... aw a Cmd+ resolve this, but the whole design do to hell nicely :)

This is really cool. One of the most useful search engines I've seen in a long time, not to mention open source.

impressive user iteraction, and fake queries seem to return good results. i'll use the engine throughout the day and see if the results are good 'nuff.
