   Dear all,   
      
   I am implementing a search system. I would like to seek your   
   suggestion on re-ranking methodology. My problem is that I have a set   
   of resulting documents to a query and each one of them with a matching   
   score and also a list of relatedness score between each two of them. I   
   would like to re-rank my resulting documents by downgrading the score   
   of those near duplicate results. This is in order to keep the results   
   with precision but also to enable diversity. I would like to know   
   whether there exists any standard approach to do so?   
      
   Any suggestions or pointers would be highly appreciated.   
      
   Best regards,   
      
   Sengly
