Is the project learning to rank need to be improved?
HI, Parth:
Thanks for your reply.
There's xapian-letor folder in current master trunk, is this code merged in
2011? the letor code of 2012 is not merged to the trunk?

Introduction and Discussion for Learning to Rank Framework
Hello All,
This time we are working on a weighting scheme "Learning to Rank" which
involves machine learning and its a supervised ranking scheme unlike
unsupervised schemes like BM25 under GSoC project.
This mail intends to discuss the framework of the Learning to Rank in Xapian
as a whole. I have thought of the following framework, pour in your insights
or issues for the same. This is

Is the project learning to rank need to be improved?
As Olly has already pointed out the 2012 branch is not merged.
I think there are some compilation errors in the branch.
The code in branch is better refactored. The Ranker and FeatureManager
classes are well defined and implemented.
Parth.

Learning to rank
Dear Sir,
I am Pankaj Singhal from Jaipur, India. I am very much
interested and strongly looking forward in getting involved in this project
Learning-to-Rank.
My previous experience in this field is good. Last semester I did a similar
job of ranking the URLs of the given huge dataset based on their attribute
values. The dataset consisted hundreds of thousands of URLs and each url

I'd suggest that a good thing to look at would be functional tests of the metrics and algorithms in Hanxiao Sun's work from this summer. You'll generally need to go either to the original paper, or find an alternative implementation, to build up a series of tests that demonstrate that the implementation is doing what it is supposed to.
Xapian-core contains a test framework which it

[GSoC2012] Learning to Rank: few thoughts/issues
Hello,
I would like to work with Orange as part of GSoC 2012(and continue
henceforth). Apologies for joining in a bit late- i was waiting to get a
proper grasp of things before discussing it here. Currently I am a Masters
students in Mathematics with my bachelors in Computer Science[integrated
dual degree]. Over the last year and a half, I have worked on a few ML

Hi
Maybe I can start off with Hanxiao's branch but I can see there are two
repos.

which one should I pick?
I have already successfully built xapian from the git repository (

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.

I am interested in the project 'Learning to Rank Click Data Mining', and
here is my current understanding about this project:
1. where can we get your click data. we can extend the omega to supports
log the user's search and clicked documents
2. the specific click data information and format. Based on some paper and

Considering Parallel computing for Letor
Hi everyone,
My name is Shreedhar Pawar. I have already introduced myself on
Xapian-discuss...
I feel that the Xapian Search/Letor Algorithm, can speed up using
Parallel computing. Techniques like Map-reduce, 'compact n split', radix
sort, scan, parallel hashing n much more can be used to speed up the
learning algorithms as well as the search... support vector machines in

Access to Datasets for Learning to Rank
Hi,
Would like to know if anyone has access to the datasets that can be
used for xapian-letor or has worked with them in the past. Also would like
to get some guidance on using xapian-evaluation.

Patch: New features for Learning to Rank
Hello,
Please find attached the patch which contains new features for the LETOR
framework which increases the total features from 19 to 37. In my proposal
I had mentioned of having a final count of 44 IR specific features apart
from those learnt by unsupervised feature learning part via Deep Learning.
So I am left with 7 out of those 44,of which 6 I will be implementing

Letor re-factored code
Hello Rishabh,
The attached diff file should help you to refactor the existing letor code
and plug in your code easily. I have defined the header files with the
necessary flow. I have also specified the ranker class, which should be
implemented by a new LTR models, ListNet and ListMLE in your case. The
evaluation file should be used for validating the performance of the
algorithm in the training

Hi,
Can someone tell me what was Gaurav Arora's exact contribution in the
Clustering Search Results part during GSoC 2014? I guess that will be
more helpful in understanding his code.
