Hey Richhiey, Most probably Xapian is used with CYGWIN in Windows and Windows Specific Code in Xapian is based on CYGWIN, However we would be able to help you out with this issue, if you could pastebin whole 'gnu-make' generated report.

Hello devs, I have filled out the repo link on TRAC as suggested. I'll also keep the journal updated on TRAC from now on. I am almost done with defining all the base classes required for the clusterer and have started coding the euclidian distance metric. This should be completed by tomorrow after which I'll be spending one day to test and make sure everything functions as expected, so

Hello xapian devs, I had shown interest in writing a krovetz stemmer for xapian and spoke to James Aylett about it. Since it was hard to code the stemmer in snowball, I came up with a C++ implementation of the stemmer. But since it is a dictionary based stemmer, im having problems on deciding how to create the dictionary. I did check out some of the implementations of the Krovetz stemmer online

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

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...

...uality) to be working well. As Olly has mentioned in one of his comments on the PR, it wouldn't be ideal to use hard coded criteria for feature selection. Thus using something like an ExpandDecider would certainly be great. I will look into it and make my approach clear as I go ahead.

Hi, I am currently pursuing my computing science bachelors degree at university of Alberta, Canada. My speciality lie in Information retrieval, machine learning and data mining. In order to get hands on experience with real world information retrieval systems, I would like to contribute to the Xapian project. I have been going through some of the project ideas in

Hello devs, My name is Richhiey Thomas.and I've been selected for GSoC 2016 for the project Clustering of Search Results. I would like to thank the Xapian GSoC admin's for giving me this opportunity and James and Olly to help me with my first merge request. In the next two to three days, I'll critically examine all t...

Hello devs. I would like to propose how I plan to go about improving and getting a system that can be integrated into Xapian in this GSoC for the clustering branch. I have identified three areas of work which were not touched last time. 1) Automated Performance Analysis I had roughly implemented 2 evaluation techniques previously (Distance b/w document and centroids within clusters and

Hey Parth, Thanks for the reply. I am considering implementing a cosine distance metric too, along with euclidian distance because of the dimensionality issue that comes in with K-Means and euclidian distance metric. That does help when we deal with sparse vectors for documents. The particular problem I'm having is representing centroids in an efficient way. For example, when we find the mean

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

...the final week for GSoC is starting now, should I list the API that was merged into a different branch before as merged or as yet to merge? And incase I am not able to complete PSO by 23rd august since I am behind the timeline, would it be possible for me to continue it later on? Thanks.

...g some time to sink in :) Say I start with the Clusterer class, I create a ClustererImpl class which is the internal class that Clusterer points to. But since Clusterer is abstract, and KMeans inherits from Clusterer, how do I maintain the inheritance and do the same for KMeans? Thanks.
