"The search result clustering toolbar is a tool for searching web with the Search Result Clustering (SRC) technique, which is developed at Web Search and Mining Group in MSR, Asia.

It on-the-fly clusters a certain search engine's search results into different groups, and provide meaningful and readable names for these groups. SRC changes the traditional representation of search results into a non-linear way, so as to facilitate user's browsing. Traditional clustering techniques don't work for this problem because the documents are short, the cluster names should be readable and the algorithm should be efficient for on-the-fly calculation. Our method take the whole problem in another way and overcome the difficulties in traditional clustering method. Basically, we try to first identify salient topics by identifying distinct and independent keyword, and then classify the search results into these topics. Please visit the MSRA Search Result Clustering web site for more information."

The left-hand tree JavaScript doesn't work well (expand and collapse) for me in Firefox or Opera, but otherwise it's pretty cool. RSS results too. No ads yet. I haven't tried the toolbar (and am not gonna).

If I wanted to use MSN's engine, I think I'd prefer this to the new Windows Live stuff, which just seems fat and slow by comparison.
