Xapian devel - Feb 2014 - Next Steps.

Hey guys,

    I had introduced myself earlier on IRC. I talked to Parth and had a
brief chat with Olly, but just to re-iterate I'm Tejas Nikumbh, and I'm
interested in contributing to Xapian for GSoC this year. I'm specifically
interested in letor and weighing schemes projects.

    I've been able to build xapian on my machine without any errors via the
Guidelines on the Hacking file in Xapian core. I was wondering if there are
any simple issues in xapian which I might try and resolve in order to get
familiar with the codebase and push a few commits?

Thanks,

To be more specific, I've gone through the documentation of xapian-letor
and have been trying to look into libSVM. Also, for weighing schemes, I'm
studying the various schemes as olly suggested.

Any more pointers would be appreciated.

Thanks,

There's a list of "bite size" projects here, which are a good
place to
start:

http://trac.xapian.org/wiki/ProjectIdeas

For the weighting schemes project, trying to add support for an
additional normalisation to TfIdfWeight would help give you an idea
of what's involved.

Have you successfully built the latest xapian-letor?  I think the one
from the 2012 GSoC branch is probably the best starting point, but Parth
can probably give more insight into the current state of things.

There's a xapian-letor on trunk, merged after GSoC 2011, which isn't
built by default.  If you "rm xapian-letor/.nobootstrap" and rerun
the bootstrap script, it should get built.

Cheers,
