MSN working on clustering of search results

Clustering still seems to be a topic of wide interest in the search domain. I concede that clustering will remain a best-effort algorithm for the most of it - as there will always be clusters which make no sense or are unnecessary - but still is extremely beneficial for the end user.

MSN seems to be experimenting with clustering for their search engine. MSR Asia has developed the MSRA SRC Toolbar and also a web interface for clustered search for MSN, MSNBC and MSNBETA. Try it out here.
