for implementing it,we can use Documentsource class in our previous
clustering approach and create a binary tree
and perform and topdownsplitting and then bottomup merging.
First we have to implement feature extraction from text document(TFIDF
would be a good choice) which is implemented in xapian weighting schemes.
Then we will implement function to compute distances between documents
based on normalized TF-IDF Matrix.
Based on distances we...

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
