The refining feature was allready there at http://www.teoma.com , a askjeeves acquired company. askjeeves acquired it in 2001, they are looking very late for adding this feature on their main site. The same thing has been applied by http://www.clusty.com there is diefference in the clustering of both.
I am also working on the same area as my M.E. project, my results are looking comparable with clusty, it is on testing phase. This definately improves the precision. |
