> Key: CTAKES-268
> URL: https://issues.apache.org/jira/browse/CTAKES-268
> Project: cTAKES
> Issue Type: Improvement
> Components: ctakes-core

> Environment: Mac OS X
> Reporter: Roberto Costumero Moreno
> Labels: patch
> Fix For: 3.1, 3.2, 3.1.1

>
> Fixed the problem where SentenceDetector did not work as expected due to
> changes in the OpenNLP API.
> I have changed code around line 300:
> logger.error("----------------------------------------------------------------------------------");
> logger.error("Need to update yet for OpenNLP changes "); // TODO
> logger.error("Commented out code that no longer compiles due to OpenNLP API
> incompatible changes"); // TODO
> logger.error("----------------------------------------------------------------------------------");
>
> FileReader datafr = new FileReader(inFile);
> EventStream es = new BasicEventStream(new
> PlainTextByLineDataStream(datafr));
>
> GISModel mod = GIS.trainModel(es, iters, cut);
> SuffixSensitiveGISModelWriter ssgmw = new
> SuffixSensitiveGISModelWriter(
> mod, outFile);
> logger.info("Saving the model as: " +
> outFile.getAbsolutePath());
> ssgmw.persist();
> with this code:
> Charset charset = Charset.forName("UTF-8");
>
> FileInputStream inStream = new FileInputStream(inFile);
> ObjectStream<String> lineStream = new PlainTextByLineStream(inStream,
> charset);
> ObjectStream<SentenceSample> sampleStream = new
> SentenceSampleStream(lineStream);
>
> SentenceModel mod;
>
> try {
> mod = SentenceDetectorME.train("en", sampleStream, true, null,
> ModelUtil.createTrainingParameters(iters, cut));
> } finally {
> sampleStream.close();
> inStream.close();
> }
> SuffixSensitiveGISModelWriter ssgmw = new SuffixSensitiveGISModelWriter(
> mod.getMaxentModel(), outFile);
> logger.info("Saving the model as: " + outFile.getAbsolutePath());
> ssgmw.persist();
> Seems to be working but need to be checked. I have successfully generated
> models from the examples and a new one in Spanish in which I am currently
> working.
