similar to: GSoC, Xapian Project Weighting Schemes

Hello all, I am Mohd Azeem. I want to contribute in Xapian but I am a newbie here. I wonder if anyone could help me in getting started with Xapian. I have some basic knowledge of IR and implemented TF*IDF and PageRank schemes, and also implemented Inverted Index and Web-Crawler. regards, Azeem -------------- next part -------------- An HTML attachment was scrubbed...

Hello guys, I have an weight value which is calculated by some factor and i need to add the weight with the relevancy value of a result and sort it with that value is that possible in xapian.

I was thinking about this some more: Is there a reason I can't just weight by some function of recency at indexing time? $weight = get_weight_based_on_recency(...); $tg->index_text($txt,$weight); If I wanted to allow the user the option of searching either in recency-weighted mode or not, I could index each document into 2 different databases, one with and one without. This avoids

I did some digging and found a thread from 2011 talking about how to subclass Xapian::PostingSource in order to incorporate the date or recency of a document in its weighting: http://thread.gmane.org/gmane.comp.search.xapian.general/8849/focus=8856 As in that thread, I want to be clear that I don't want to sort by date, but rather incorporate date information into the score by which I

hi if i remove the rule for transparent redirection from my firewall script then it works well. what can be the connection of transparent redirection with samba please help me out. i m in a grate trouble. the detailed problem is below Regards Azeem >From: "azeem ahmad" <azeem484@hotmail.com> >To: samba@lists.samba.org >Subject: [Samba] iptables and samba >Date:

Hi, folks. I don't know much about C++, so please excuse my newbie question: I just tried to include Xapian in a dummy Cocoa project, ie created a new project and added the libxapian.a file installed via MacPorts. When I include xapian.h in an Objective-C++ file (either mm or h), the compilation fails with the following message: ================= In file included from

Hi all, I am trying to implement a scheme where documents in an MSet will be sorted based on relevance as well as geographical distance from a given (non-fixed) point. I understand that this can be accomplished by using PostingSource in order to implement a custom weighting scheme that would combine BM25 weighting and distance. The problem is that I am using perl and PostingSource is not

Hi Rishabh, I took some time out in the recent days to work on the refactoring. And now it looks like I have included all the files necessary for the complete code. I am sure if it will be quite easy for you now to start with the new code. I would like you to complete it by implementing (copy/paste/little modification) some of the methods. https://github.com/parthg/xapian To make it easier,
