...ions. you can refer the paper for more details about time complexity and performance http://web.cs.ucla.edu/~zaniolo/papers/chp%253A10.1007%252F978-3-642-37456-2_10.pdf 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
