A query about clustering Idea
Hello sir! Thank you for your gentle reply, I have visited to the github repository before but the code was not commented properly still I am trying to understand and figure out the redundant task in the algorithm by reading the code. For the same I asked you if there is any other document or information is available with you which can help me to understand it better would be great. It's okay

A query about clustering Idea
You mean, to take review on proposal I need to create an application? and if it is the case then please tell me how to create application?

A query about clustering Idea
Sir, I have prepared a draft proposal for clustering problem. If you have previous year's accepted proposal please share it, that would be very helpful. And also I have attached my proposal, please review it.

clustering technique using lsi
Hello sir, You have interpreted correctly that clustering will be done by generating the ring around the Document(i.e. the basic idea of LSI). But it is not like increasing the radius and the next shell will be another cluster, Rather it would pick one document (based on relevance score) and form a ring around it to cluster the document, then from the remaining documents(not in the cluster but

clustering technique using lsi
I am still trying to find some faster clustering technique for search result. One technique which strike to me is, using the Latent Semantic Indexing for Clustering the search result can give better results. In which we don't even need to iterate over different values of 'k'(in K-means algorithm) to cluster documents rather we can cluster whole search result in one go. How Latent

Clustering Project
sir, Till now I was confident enough to handle this project in the summer but the only thing which I had a little concern was the algorithm that I proposed. The thing is previously while writing the proposal I did not read much research papers on clustering, just the few I read and an idea strike to me and I wrote the proposal and discussed with you. But for last few days I was searching for the

Introduction and Doubts
I was not sharing it on maling list because i thought that someone can use all ideas i proposed in their GSOC proposal. Surely i will contribute to xapian project. sorry if that was against the rules The algorithm is not developed by me but after having much research on various clustering techniques. I found that there is a new algorithm called CLUBS(Clustering Using Binary Splitting) which gives

Introduction and Doubts
Tf-idf is most used used weighting scheme is easy to understand and has been used in other frameworks like lucene and many other places. okapi bm25(implemented in xapian) is theoretically better/improved measure than tf-idf and i am looking into various other weighting scheme which are there in xapian or can be implemented like TF-ICF(term frequecy inverse corpus frequency),TF-RF(term

GSoC 2016 - Introduction
Hello, Thanks James for the reply. That cleared a few things out. Apologies for replying late because of exams going on. I was going through the previous clustering API to understand how it worked and it seems like the the approach for construction of the termlists which are used for distance metrics use TF-IDF weighting with cosine similarity, which is very similar to the approach I would need

GSOC-2016 Project : Clustering of search results
Hello devs, I am Richhiey Thomas, pursuing my third year of undergraduate studies in Computer Science from Mumbai University. I had gone through the project list for this year and the project idea based on clustering caught my attention. I spoke to Assem Chelli on IRC who guided me to the code and got me started. I started going through the code and have successfully built Xapian on my machine.

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:

Introduction and Doubts
Hello All,I am Nirmal Singhania from NIIT University,India. I am interested in Clustering of search results Topic. I have been in field of practical machine learning and information retrieval from quite some time. I took various courses/MOOC on Information retrieval and Text Mining and have been working on real life datasets(KDD99,AWID,Movielens). Because the problems you face in real life ML/IR

GSoC 2016 - Introduction
Before going ahead with the tests as you mentioned above, I would just like to clarify a few higher level things that I am still in doubt about. 1) As discussed during the IRC interview, I was suggested about first implementing a normal K-means clustering implementation and then adding on the PSO module as a functionality that can be used to improve quality of clustering for speed as a trade off.

Regarding GSoC 2016 project idea
Hello, I am Ainish Dave from Ahmedabad, India. I am currently pursuing my masters level degree with background in computer science. I browsed through the list of organizations on the GSoC program page and Xapian was the one which closely matched with my interest and background. I had some queries: 1) I am interested in the project 'Clustering of Search Results'. I have followed the

Weighting Schemes: Evaluation results
Hi, Evaluation of pivoted normalization ("PPP") of tf-idf weighting scheme is also complete now. I have also evaluated the default tf-idf normalization ("ntn") and other normalizations combinations involving pivoted normalization in wdfn, idfn and wtn component as "Pxx", "xPx" and "xxP" normalization strings respectively to have a clear idea about

K MEANS clustering
Hello, I've been working on the KMeans clustering algorithm recently and since the past week, I have been stuck on a problem which I'm not able to find a solution to. Since we are representing documents as Tf-idf vectors, they are really sparse vectors (a usual corpus can have around 5000 terms). So it gets really difficult to represent these sparse vectors in a way that would be
