: What is TextMiner?
: TextMiner is a tool built by a research team at School of Computing, 
: Dr. Wang Ke and student Xu Chu, for clustering a collection of 
: transactions (such as text documents). 
: How TextMiner works?
: Traditionally, the similarity of a cluster of transactions is defined in 
: terms of pairwise similarity of the transactions in the cluster. For 
: example, all distance based matrics are a form of pairwise similarity. 
: Approaches using pairwise similarity suffer from two serious limitations. 
: First, computing the similarity of a cluster is very expensive because 
: every pair of objects in the cluster must be examined in general. Second,
