Hello all, I have been doing some evaluation of Lucene on a TReC collection and get a rather disappointing mean average precision (MAP) of 11%. Other sources seem to report a MAP of about 20%.
So I am here to ask all of you who have done some Lucene evaluation - what did you find Lucene's MAP to be? Did you do anything to special (e.g. query expansion) to get it higher? Thanks Dana -- View this message in context: http://www.nabble.com/Lucene%27s-Mean-Average-Precision-tp17049412p17049412.html Sent from the Lucene - Java Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
