Subject Re: How to normalize Lucene score?
Date Mon, 17 Aug 2009 08:32:36 GMT
Hi Prashant,

we let convergate the scores to 1 - whereby they will never reach one, to have
also correct ratings with respect to higher Lucene scores which are more
or less open-ended:

normalizedScore = 1 - [ 1 / (1+luceneScore) ]


best
