Weighting Schemes: Evaluation results

​I can say FIRE is also a reliable source but INEX/TREC are better. INEX
can give you free access and TREC is not freely available. I had used INEX
for xapian in the past and some details are here:
https://trac.xapian.org/wiki/GSoC2011/LTR/Notes#IREvaluationofLetorrankingscheme

I roughly remember that there was a discussion with our this year GSOC
student Ayush about INEX data. He had also obtained it, this would also be
a good way to collaborate with him :) and try to establish a common
evaluation dataset for future.

Cheers
