Class Target2BIOFormat

  • All Implemented Interfaces:

    public class Target2BIOFormat
    extends Pipe
    Creates a LabelSequence out of a TokenSequence that is the target of an Instance. Labels are constructed out of each Token in the TokenSequence to conform with BIO format (Begin, Inside, Outside of Segment). Prepends a "B-" to Tokens that leave a background state and an "I-" to tags that have the same label as the previous Token. NOTE: This class assumes that subsequent identical tags belong to the same Segment. This means that you cannot have B B I, only B I I.
