== Abstract ==

Basically, It'll shows how to construct the matrix from the files.

This word count matrix (document-word) approach is often referred to as latent semantic indexing and document clustering (Of course, A word frequently present in all documents will not be useful for clustering -- The length of all documents is not uniform so a lengthy document will have higher word counts).
