A Little Help
Hi Rishabh,
I think its better not to expose RankiList to Letor.h and make it better
user friendly. So my suggestion is to convert RankList to the following
statement in this method.
std::map<Xapian::docid, double> letor_score(const Xapian::MSet & mset);
So just convert the RankList in std::map<Xapian::docid, double> format in
the methods where you need to return.
Parth.

Following methods are very general methods which uses above all the methods
in order to make a platform between xapian and Machine Learning.
void prepare_training_file() - This method prepares the training file which
is used by the Machine Learning(ML) Algorithm in our case SVM[Support Vector
Machine Tool] to build the model. This method will be made public because
user can prepare its own training file suitable to his/her application,
supplying necessary things...

Some questions about Letor project
Hi all,
Thank you for giving me the opportunity to work with Xapian :) I am Jiarong
Wei, a third year undergraduate student in Zhejiang University, China. In
GSoC 2014, I will work on Letor module with Hanxiao Sun.
Here are some questions I encountered these days,
1. In letor.cc, we have two parts of functions: the training part and
the ranking part. I?ll use SVMRanker as an example. The
