Method Detail

featurize

String[] featurize(String[] toks,
                   String[] tags)

Generates chunk tags for the given sequence returning the result in an array.

Parameters:

toks - an array of the tokens or words of the sequence.

tags - an array of the pos tags of the sequence.

Returns:

an array of feature tags for each token in the sequence.

topKSequences

                                            String[] tags)

Returns the top k chunk sequences for the specified sentence with the specified pos-tags

Parameters:

sentence - The tokens of the sentence.

tags - The pos-tags for the specified sentence.

Returns:

the top k feature sequences for the specified sentence.

topKSequences

opennlp.tools.util.Sequence[] topKSequences(String[] sentence,
                                            String[] tags,
                                            double minSequenceScore)

Returns the top k chunk sequences for the specified sentence with the specified pos-tags

Parameters:

sentence - The tokens of the sentence.

tags - The pos-tags for the specified sentence.

minSequenceScore - A lower bound on the score of a returned sequence.

Returns:

the top k feature sequences for the specified sentence.
