I am finding it difficult to create my own model openNLP. Can any one tell me, how to own model. How the training shouls be done.

What should be the input and where

Copy the data in data and run below code to get your own mymodel.bin .

Can refer for data=https://github.com/mccraigmccraig/opennlp/blob/master/src/test/resources/opennlp/tools/namefind/AnnotatedSentencesWithTypes.txt

public class Training {
       static String onlpModelPath = "mymodel.bin";
       // training data set
       static String trainingDataFilePath = "data.txt";

       public static void main(String[] args) throws IOException {
                       Charset charset = Charset.forName("UTF-8");
                       ObjectStream lineStream = new PlainTextByLineStream(
                                                       new FileInputStream(trainingDataFilePath), charset);
                       ObjectStream sampleStream = new NameSampleDataStream(
                                                       lineStream);
                       TokenNameFinderModel model = null;
                       HashMap mp = new HashMap();
                       try {
                              //         model = NameFinderME.train("en","drugs", sampleStream, Collections.emptyMap(),100,4) ;
                                       model=  NameFinderME.train("en", "drugs", sampleStream, Collections. emptyMap());
                       } finally {
                                       sampleStream.close();
                       }
                       BufferedOutputStream modelOut = null;
                       try {
                                       modelOut = new BufferedOutputStream(new FileOutputStream(onlpModelPath));
                                       model.serialize(modelOut);
                       } finally {
                                       if (modelOut != null)
                                                       modelOut.close();
                       }
       }
