Part I: Data Collection (5%)

A Small Text Collection based on top 25 retrieved documents from model1 and model2:

• group1 (25 retrieved documents from model1)
• group2 (16 retrieved documents from model2)

Automatic Indexing:

• The vocabulary file for this test collection (with default settings: no stemming, stopped words removed)
• The original document-term matrix (with top 5 terms based on info-gain) 

SOM inputs and outputs:

• The document-term matrix prepared for SOM input
• The SOM matrix.cod output file
