SequencePath

public SequencePath()

Method Detail

add

public void add(SequenceEmission sequenceLabel)

Parameters:

sequenceLabel - A sequence label to be added at the end of this list

compareTo

public int compareTo(SequencePath o)

Specified by:

compareTo in interface Comparable<SequencePath>

getAssignedLabel

public Label getAssignedLabel(int i)

Parameters:

i - the index of the targeted element

Returns:

the label assigned to the i-th element

getAssignedSequnceLabels

public List<SequenceEmission> getAssignedSequnceLabels()

Returns:

The collection of SequenceLabels produced during the sequence labeling process

getHistoryBefore

public String getHistoryBefore(int targetId,
                      int historySize)

This method generate a string representing an artificial feature used in the labeling process. In particular it reflects the $h$ labels preceding a targeted element.

Parameters:

targetId - the index of the element whose previous labels are required

historySize - the number of labels to return

Returns:

a string that is the concatenation of labels preceding a targeted element in the sequence

getScore

public Double getScore()

Returns:

the score assigned to this labeling

setAssignedSequenceLabels

public void setAssignedSequenceLabels(List<SequenceEmission> assignedLabels)

Parameters:

assignedLabels - The collection of SequenceLabels produced during the sequence labeling process

setScore

public void setScore(Double score)

Parameters:

score - the score assigned to this labeling

toString

public String toString()

Overrides:

toString in class Object
