Xapian devel - Mar 2017 - Introductory mail

Hello Xapian Community,
I have gone through the project ideas and would like to work on "Weighting
Schemes". Can someone please help me out to get started with it. Please
share some tutorials or research papers if available.

I am currently working on the project of video summarization which uses a
information retrieval,so I would like to apply my knowledge in this project.

Regards,

We generally recommend starting by getting the code and getting the necessary
tools installed to successfully build it, then trying to work on something
small to start to get familiar with the code.  We've put a wiki page
together
to help with this process:

https://trac.xapian.org/wiki/GSoC%20Guide

If you want research papers for suitable weighting schemes, you'll have to
take a look through the literature for them.

We now implement most of the well known schemes (though as the project idea
notes, not all the SMART normalisations are supported yet), but papers are
still being published proposing new schemes or variants on existing schemes
(like BM25+/PL2+/Dir+/Piv+ which Vivek implemented last year).

There's also scope for working on implementing tracking of more statistics
to allow some of the already implemented schemes to be better optimised.

Cheers,
