Clustering search results to increase their diversity..

["Subbarao Kambhampati" <rao@asu.edu>]

I added a slide summarizing the discussion on why top-k results
should simultaneously satisfy two constraints (be as close to the query
as possible while being as far from each other as possible). 

As I said one way to increase result diversity is to get results in terms of their
proximity to the query, and then cluster them and give cluster representatives. 

Vivisimo.com is such a seach engine. 

Here is an example:

http://vivisimo.com/search?tb=vivisimocom&query=kambhampati&x=0&y=0


(you can try other queries..)
