Taxonomy - how many training documents needed for automatic classification?

33 Views

Greetings,

I have an example based taxonomy.

I have trained the taxonomy manually with about two documents and expected it to classify automatically after that which it has not done.

According to the URL below

http://www.scribd.com/doc/7234683/Retrieval-and-Classification-TREX-Features-and-Functions

it is mentioned that "You can also classify documents automatically. A prerequisite for this is that there are existing document classes with sufficiently correctly classified documents that meet the classification criteria"

Please advise if training the taxonomy with only two documents which I did was too little - exactly how many documents are needed? (the above URL does not give an indication of a number)

Regards,

Keith
