NDCG

[Ian Soboroff <ian.soboroff@nist.gov>]

Hi, all... I'm working on an implementation of NDCG.  While my math
looks right (to me at least), I'd love to test it on some real retrieval
runs.  Unfortunately, I can't find any runs with corresponding NDCG
scores.  (I thought NTCIR did this but their online proceedings don't
report NDCG.)

Alternatively, I'd appreciate seeing a known-good implementation so I
can be sure of my results.

Thanks in advance,
Ian
