Roberto Costumero Moreno updated CTAKES-268:
--------------------------------------------
Description:
Fixed the problem where SentenceDetector did not work as expected due to
changes in the OpenNLP API.
I have attached a patch file and the sentence file I have used and the model
that it has generated.
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.
Updated: Attached new Patch.

I have changed code around line 300:

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
