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

Olly, Thanks a lot! I installed Xapian 1.2.25 on Ubuntu 14.04. How to set environment variable XAPIAN_CJK_NGRAM? I'm a newbie to Xapian.

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.

Hi Olly, Perhaps you could announce such updates a bit more out in the open. For instance send a message to the discuss-list and/or put piece of information about the last version on the index of xapian.org.

Hello devs, I would like to take up the bite sized project on adding a match command to omega script to perform a regex match. I would just like to know whether the way I am approaching this is right or wrong. The way I am planning to approach it is: 1. Add a new command in query.cc and write the implementation for this command 2. Inside implementation, we will use pcre library in a similar way

I think what i did is the same with you except i use make rather than make -sj8, and I did as root. And I do as you wrote again: root at hurricanetong-VirtualBox:/home/hurricanetong/xapian-1.2.17/xapian-core-1.2.17# ./configure [...] root at hurricanetong-VirtualBox:/home/hurricanetong/xapian-1.2.17/xapian-core-1.2.17# make -sj8 Making all in .

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

Hello Olly, I read about Xapian and SWIG and the bindings that Xapian has with other languages. According to what I've read, I understand that Xapian is a search engine library written in C/C++. It can be integrated with web applications which handle large amount of data. But since the web applications may be written in a variety of languages a binding is required for the web app to be able

Hi, I didn't notice php7 bindings were included since 1.4.2. That's good. But I have some problems with these, I compiled xapian-bindings 1.4.3 in a debian 9 container, but had no luck with it: php -r 'require "/usr/share/php/xapian.php";var_export(Xapian::version_string());' '1.4.3'Segmentation fault (core dumped) Regards, Pascal Bonne journée Pascal

Hi Olly, Wouldn't setting the weight of terms in title back to normal (e.g. 5 to 1) by below line, automatically adjust the wdfs and field lengths? indexer.index_text(title, 5, "S"); -> indexer.index_text(title, 1, "S"); if it does not then we should include that part in the patch too. I like to create a patch for xapian-letor for resolving common code of xapian.

I think there is a development in the bug #616. The exception obtained is: Exception in thread "main" java.lang.IllegalArgumentException: No enum class org.xapian.TermGenerator$flags with value 0 at org.xapian.TermGenerator$flags.swigToEnum(TermGenerator.java:143) at org.xapian.TermGenerator.setFlags(TermGenerator.java:71) at org.xapian.examples.SimpleIndex.main(SimpleIndex.java:54)

This might be a little late but I was engaged in my university examinations. Moreover, I have an exam even today so apologies for the delay. Also, I had to change my project from weighting schemes to improve to improve estimated total number of results as weighting schemes was demanding a lot of time going through it. I would really appreciate if you could review my proposal asap.
