Method Detail

getTokensAndLabels

public static java.util.List<<any>> getTokensAndLabels(java.lang.String labeledResult)

Parameters:

labeledResult - labeled result from a tagger

Returns:

a list of pairs - first element in a pair is a token itself, the second is a label (e.g. or I-) Note an empty line in the result will be transformed to a 'null' pointer of a pair

getTokensWithLabelsAndFeatures

public static java.util.List<Triple<java.lang.String,java.lang.String,java.lang.String>> getTokensWithLabelsAndFeatures(java.lang.String labeledResult,
                                                                                                                        boolean addFeatureString)

Parameters:

labeledResult - labeled result from a tagger

Returns:

a list of triples - first element in a pair is a token itself, the second is a label (e.g. or I-) and the third element is a string with the features Note an empty line in the result will be transformed to a 'null' pointer of a pair
