I'm sorry I can't see it! Which class should I be looking into?
I can only see 3 train methods in the NameFinderME...they basically take
the same args + |AdaptiveFeatureGenerator
<http://opennlp.sourceforge.net/api/opennlp/tools/util/featuregen/AdaptiveFeatureGenerator.html>,
||iterations, cutoff|...
None of the args is of type TrainingParameters. I s there another
NameFinder class somewhere?

Use the train method that gets a TrainingParameters.
Check how to create it in TrainingParameters.defaultParams().

Hi William,
First of all thanks for the prompt reply, however I am using the API not
the cmd tool...
where do I pass that properties file?

Yes, you can. Just create a properties file like follows
Threads=8
Iterations=100
Algorithm=PERCEPTRON
Cutoff=0
and train passing the properties file in the argument -params
Note that perceptron models benefit from cutoff 0. For Maxent models
usually you set something like 5. I usually try different values with the
CV tool to find the best cutoff value.

Hi all,
is it at all possible to train a name-finder using perceptron instead of
maxent? The documentation says that openNLP supports both but I can only
find examples for pos-tagging and nothing else (sentence detection ,NER,
chunking etc etc)...
thanks in advance...
Jim
