Training a new POS tagger

[Svetoslav Marinov]

Hello,

I am sorry if the question is naive but can someone help how one should train a 
POS tagger via the API. The documentation on the web uses a deprecated method 
and the API is not very helpful.

So my specific question is how should the trainParameters be specified

            model = POSTaggerME.train("se", sampleStream, trainParameters, 
null, null);

The same applies to the command line options. Is there any guide to how I 
should choose and write the training parameters.

Also how does one use the POStaggerEvaluator and cross validator?

Thank you in advance!

Best,
Svetoslav
