evaluate the model

[Amal Elmah <am...@hotmail.com>]

I built a model using Opennlp using the instructions in the documentation
so I used training data in such the following format:
 
<START:person> Pierre Vinken <END> , 61 years old , will join the board as a nonexecutive director Nov. 29 .
Mr . <START:person> Vinken <END> is chairman of Elsevier N.V. , the Dutch publishing group .
<START:person> Rudolph Agnew <END> , 55 years old and former chairman of Consolidated Gold Fields 
 
I am now trying to evaluate this model but I don't know if the test data should conatin tag as the above or not.
 
thanks alot

The OpenNLP built-in evaluation always needs the tags in the test data, 
otherwise it assumes that
the data with no-tags is correct and counts every name as a mistake.

You also need much more training data.

Please feel free to send us a patch to our documentation to clarify this.
