This class provides a simple implementation of the OpenNLP POSTagger interface. This implementation doesn't perform part-of-speech tagging, per se. Instead, it retrieves part-of-speech tags from the CAS using the InputTypesHelper that it is instantiated with. This class is not intended for use outside of the ParserAnnotator.

Constructor Summary

CasPosTagger(InputTypesHelper<TOKEN_TYPE,SENTENCE_TYPE> inputTypesHelper)

Method Summary

void	setTokens(List<TOKEN_TYPE> tokens)
List<String>	tag(List<String> sentence)
String	tag(String sentence)
String[]	tag(String[] sentence)
opennlp.tools.util.Sequence[]	topKSequences(List<String> sentence)
opennlp.tools.util.Sequence[]	topKSequences(String[] sentence) This method will only return a single sequence corresponding to the part-of-speech tags that have already been assigned to the tokens in the CAS as part of some upstream processing that precedes running of the ParserAnnotator.
