public class Chunker
extends org.apache.uima.analysis_component.JCasAnnotator_ImplBase

This class provides a UIMA wrapper for the OpenNLP opennlp.tools.chunker.Chunker class. This wrapper can generate chunks of any kind as specified by the chunker model and the chunk creator.

Field Summary

static java.lang.String	CHUNKER_CREATOR_CLASS_PARAM "ChunkCreatorClass" is a required, single, string parameter that specifies the chunker creator class to instantiate.
static java.lang.String	CHUNKER_MODEL_FILE_PARAM "ChunkerModel" is a required, single, string parameter that contains the file name of the chunker model.
