EntropyNameFinder.TrainModel Syntax for training custom model

[alijundi]

Dear @AlexPoint

I am using the below code to train a custom model for my case. I can see the model being written but I am not sure if the syntax of the text file is correct.

I use the below format in the training file:
PANEL NAME: <NAME>MDB</NAME>
Where NAME is the named entity

var bestmodel = OpenNLP.Tools.NameFind.MaximumEntropyNameFinder.TrainModel(EntityExctractor_trainingFile, 5, 2);
SharpEntropy.IO.BinaryGisModelWriter modelwriter = new SharpEntropy.IO.BinaryGisModelWriter();
modelwriter.Persist(bestmodel, EntityExctractor_outputFilePath);

Any pointers on how to proceed?

I Also tried
PANEL NAME: <START:NAME>DB<END>

same issue!
