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?

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.

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

Hi, Sorry for the long hiatus. I was caught with some other deadlines. Could some one tell me some specific expectations from Letor for GSOC 2015? I am currently trying out some learning algorithm implementations but need some help with it. Can Parth, James and others related to LETOR please tell me the IRC availability for the next few days.

Hi Parth, I have a few questions- 1. Could you please provide me with the link for query-file, qrel-file for the dataset available at http://www.mpi-inf.mpg.de/departments/d5/software/inex/ . 2. I wanted to know how automated testing would be implemented. Will there be test cases like a test query must match this particular N results and this particular ranking. Or will it be in terms of

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

Hi, My name is Abraham and I am a 2nd year college student from Bangalore(India). I was going through your list of project ideas, and the Learning to Rank project really interested me . Unfortunately I don't really have any real experience with "Information Retrieval" and only know the basics of "Machine Learning". I was hoping that somebody could maybe point me in the

Hi Olly I will try to work on : http://trac.xapian.org/wiki/GSoCProjectIdeas#Project:LearningtoRank I will be taking a Machine Learning class the next semester and I hope that this project will help me supplement my learning in Machine Learning and also gain a bit of knowledge in IR. If you can give me ideas on how to get around with the code for LTR project, it will be awesome. I can look at

If you don't provide an implementation of wdf_upper_bound(), the default is to use the collection frequency of the term, so provided that information is available in the lucene files, the lack of wdf_upper_bound information

Hello everyone, I have recently completed my engineering in Computer Science. I came across Xapian while looking for GSoC organisations. I was browsing through the ideas page and it was written that you would be willing to mentor anyone interested in working on those projects. I am interested in this: http://trac.xapian.org/wiki/GSoCProjectIdeas#Project:LearningtoRank and this:

*Or do you mean that it's one number per document whereas the other stats are per database, so it's harder to store it?* yes, I mean this. It's a huge data. If a new doclength list(contains all the doclength in a list, like chert) is added by myself, I am concern about: 1. This doclength list may be the bottlenect in this backend, http://trac.xapian.org/ticket/326 2. Change too much

Hi Tejas, Thank you for your interest in Letor project in Xapian. We would definitely like to consider Letor for this year's GSoC project. What I would suggest you is, start playing with the code and get acquainted with it. The latest code can be obtained from http://trac.xapian.org/wiki/ GSoC2012/LTR Regards, Parth.

Dear all, My name is Hanxiao Sun and I am a master student in the University of Chinese Academy of Sciences. I am so glad to be selected by Xapian as the GSoC student. This is my first time to work with open source community. I hope I can do a good job with you in this summer ! In my proposal, I followed the scope of the LTR project on the ideas page. But, after the interview, it seems to need

Hi, all: I have wrote a demo patch for Backend for Lucene format indexes, Lucene version is 3.6.2. http://lucene.apache.org/core/3_6_2/fileformats.html Now, this demo patch just support the basic features in Lucene. Compound File(.cfs/.cfe)?term vector(.tvx/.tvd/.tvf) delete document(.del) are not supported, skip list in .fdx is not supported too example/quest.cc is used to test this demo.

Hi Maybe I can start off with Hanxiao's branch but I can see there are two repos. https://github.com/v-hasu/xapian/tree/gsoc2014-evaluation https://github.com/v-hasu/xapian/tree/gsoc2014 which one should I pick? I have already successfully built xapian from the git repository ( https://github.com/xapian/xapian) Since I am new to ML (well I dont know anything about it?), should I read the

Hi All I am Manu and recently came across the Xapian project. I will like to contribute to Xapian that gets me introduced to Information Retrieval. I have a basic knowledge of C++. Can you suggest me and help me choose a task that can be good for beginners. Thanks a lot Best Regards Manu Gupta
