[Xapian-devel] GSoC 2011 Weighting Schemes

[wuwenjin]

Hi, guys

I am Wenjin from Graduate School of Chinese Academy of Science, pursing a
master degree and my current research interests including using Data mining
and Information retrieve technology to analysis software engineering (SE)
data and support SE.

I have great interested in "Weight Schemes" project. and in the last few
days I have learnt some detail about DFR model family by reading some papers
and web page. I find that Terrier Project (http://terrier.org/)  has
implement most of DFR scheme in Java language, and  briefly read related
source of Terrier's package( org.terrier.matching.models), I think "weight
scheme" can imitate that package, of course in C++. It will be better to
implement a generic DFR  weighting model allowing any DFR to be generated
and evaluated. Since DFR is a framework  or model family, which contains
many basic models and different normalizations. thus, I want to know what
our "Weigh Schemes" includes.
