Hi, I have started getting a hang of the xapian codebase. I think I would like to try my hands on the letor module of xapian. Could you please suggest some free data set for the training and testing of letor features. I am not able to get the INEX data set from anywhere (the one mentioned by parth gupta in his GSOC 2011 projecct. Regards Karthik On Mon, Sep 22, 2014 at 4:23 PM, Olly Betts

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

Dear Olly Betts, I think the tests for the perl module Search-Xapian-1.2.21.0 might be fewer in number than the perl tests included with xapian-bindings-1.2.21. If some of the tests have similar but modified content I do not know. I am not so skilled as to interpret the compared test results. If you want to suggest a paired earlier version of Xapian to a specific xapian.bindings version, I might

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~ Manu I was glad to see you were interested in Xapian, especially the learning to rank project. There are two branch in my repo. The one named gsoc2014 is followed the thought of Parth's work in which we not assign the test set for each ranking and in another one gsoc2014-evaluation we assign the training set and test set explicitly so that we can get the evaluation score of each ranking

I am fairly confident that these issues are related to killing the scriptindex process ungracefully causing blocks that were queued for writing to disk to not get written. I mention to send you the file because it could be that you would see almost immediately with the situation is. Thanks > ----- Original Message ----- > From: oscaruser@programmer.net > To:

Hi, Olly: I post the error in the attachment, any methods to fix it? Run the command (.\lemon.exe -q -oqueryparser_internal.cc -hqueryparser_token.h queryparser.lemony) will get the error. If it is hard to fix, I will upgrade xapian to 1.4. But I worry it will cost me too much time to modify my application code. Thanks a lot. Here is the error details: lemon.c: #define LISTSIZE 30

Oh Olly, you are so kind. Thank you so much. I think you pinned out my problem. I have installed the xapian-core-1.4.22 at /usr/local/xapian-core-1.4.22 to avoid cluttering. I will try to do what you have given me. if that does not work, I will try to remove the older xapian-core-1.4.18 library wherever it is if I can locate it. Then I will give the path for the new one. GTK is just one of the

Thanks for you reply. In our case, we want to get a weight using the user' properties(age, gender, price preference) and products' properties(price, comment count, purchased amount among different gender or range of age). So our weight function is complex, no matter we use KeyMaker or PostingSource, six to eight values in slot will be used. But we find that using doc.get_value(slot)

Dear Olly, Thank you so much for the prompt and candid reply to my query; Appreciated very much. I have installed Xapian-core-1.4.22 already. But I did not know about this early before I started to configure xapian-bindings-1.4.22. I would love to bind Java, Ruby, Perl, TCL/TK, Python3, PHP,Lau: --with-csharp enable CSharp bindings --with-java enable Java bindings

I think what i did is the same with you except i use make rather than make -sj8, and I did as root.

I've uploaded Xapian 1.0.7, which as usual you can download from: http://xapian.org/download This release fixes an assortment of bugs, and improves efficiency in a few cases. It's intended to be a relatively safe incremental update over 1.0.6. For a more detailed overview see: http://trac.xapian.org/wiki/ReleaseOverview/1.0.7 The full lists of user-visible changes are linked to from

I've now uploaded Xapian 1.0.1, which you can download from the usual place: http://www.xapian.org/download.php This release mainly comprises bug fixes and performance improvements. The "simple" examples (for both C++ and the bindings) have also been overhauled and now use the QueryParser and TermGenerator classes, which makes for simpler examples and should better reflect
