Hi Vivek, I saw your comments on IRC, as noted by olly : *<olly> vivekp: (if you check the logs) - you want: ./trec_index config* *<olly> you want to run the compiled binary (no ".cc") not the source file...* But i guess you are not able to compile the setup. I can write steps and send across how to compile and sample files from config. Most of the files in config are

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

Hello xapian devs, Sorry for not getting back sooner. I was stuck up with coursework. I would like to work on LDA based document modelling and Heimstra's language modelling and would like to form a concrete plan on how to proceed. It would be really helpful if I could have a mentor to assist me with this. Looking forwards to your reply. Thanks. :) -------------- next part -------------- An

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.

Greetings, I am Hemant Kumar Singh, a computer science undergrad studying in NIT Warangal, India. I am interested to work on the project "Weighting Schemes" under the guidance of Olly Bets and Gaurav Arora; this project requires basic(or better) C++ knowledge and I've done 2 years of basic C++ in my high school. Moreover, this is my 2nd semester pursuing a computer science major in

Hi, I am Abhishek Currently Xapian::Weight follows BM25 scheme, many models such as the Divergence from Randomness (DfR) family of models, Unigram Language Model and the Bi-gram Language Model implemented two years ago in GSoc 2012 yet not merged to the master. The new weighing schemes or improvement in implementing the previous models to change the default scheme of BM25 from SMART with

Hello everyone! I'm Ayush Tomar, junior undergrad in Computer Science from New Delhi, India. I love C++ coding and working on machine learning and information retrieval project. I was exploring the GSoC ideas for Xapian and the project on "Adding Weighting Schemes" looked really interesting to me. I wanted to work on text mining/IR this summer and this idea seems perfect! I have

Hi all, I am Prajwal, a sophomore Undergraduate student from IIT Bombay, India. I want to contribute to Xapian through GSoC 2012. Specifically I am interested in the Weighting Schemes project. I have not yet taken any IR related course, but IR and NLP have always been my academic interests. I want to learn more about these topics, and I think that this is the best opportunity to do so. I

Hello Everyone, I am a second year graduate student at IIIT-Bangalore and my interest is in the field of Information Retrieval. I have successfully compiled Xapian from source and have implemented some examples. While going through the project list Weighting Schemes project is the one I was looking to contribute to. So i went through the xapian-core/weight where most of the schemes are already

Hi! I am Praveen Kumar, an Applied Mathematics student and I am interested in developing other weighting schemes for Xapian through GSOC. I did not have any formal course in Information Retrieval in our institute. The theory that I presently know is from the Xapian documentations and other references and resources mentioned on the website which I read to design our own Probabilistic Information

Hello, I am a undergraduate student at DA-IICT,India pursuing Btech in Information and Communication Technology.Major field of my Research is Information Retrieval and Natural Language processing. xapain being an powerful Information retrieval library have attracted me towards implementing stuff learned in class for this project.I have worked on entity search on RDF data,SMS based FAQ

Hello, My name is Santiago Pina and I am currently studying two BSc(Hon) simultaneously ; one in Computer Science and the other in Mathematics as part of a pilot project at Universidad de Murcia. I am very excited to contribute in open source community through the platform of Google Summer of Code 2011. I was interested in the Weighting Schemes project and in the Matcher Optimisations project,

Hello everyone, I have been working on adding support for BM25+ weighting function from the last couple of weeks. Initially, I considered modifying bm25weight.cc to add support for BM25+ function without disturbing functionalities of BM25. But that didn't work out very well. A day or two was spent trying to refactor and debug the same code. Later, I took another approach following the

Hi James, > We probably don't want them committed in git where they're evaluation > runs (because we can recreate them); a gist might be more appropriate. Sorry, I have moved results files over to gist for each individual weighting scheme. Link: https://gist.github.com/ivmarkp/secret > I can't tell, but are some of those files from FIRE? If so, they > shouldn't be

Hi, I have added support for Piv normalization in Tf-Idf weighting scheme as a intermediate step to implementing the support for Piv+ normalization. All tests pass. But I'm running into some issues with Piv+ normalization. In the Piv+ formula , there are two parameters (s and delta) that control the weight assigned. I think the way I'm serialising and unserialising these parameters has

INEX can give you free access and TREC is not freely available. I had used INEX for xapian in the past and some details are here:

Hi everyone, I am thinking of working on the following ideas for my GSOC proposal based on my discussions with Olly and my own understanding. Rather than focusing on an entire perftest module, I have decided to focus on implementing performance tests for weighting schemes based on a wikipedia dump and in addition to that, build a framework to measure the

Hi All, I'm Sumith, a postgraduate student in Monash university. I'm working in the area of Text weighting schemes and Text Mining. When I'm going through the GSOC project list, I felt interested in the 'Weighting Schemes' project. At the moment, I have worked with different weighting schemes as TF-IDF and would love to join and contribute with my ideas in this project.
