Method Detail

applyLeftWeighting

public float[] applyLeftWeighting(RandomLabel focusLabel,
                                  int distance,
                                  RandomLabel leftContextLabel)

Calculates the weight based upon the distance (in the left context) to the current label in the following manner: weight=(2^(1-distance to focus word)).

Specified by:

applyLeftWeighting in class WeightingScheme

Parameters:

focusLabel - RandomLabel in focus, i.e. the focus word whose context vector should be modified with the weighted RandomLabel in left context.

distance - leftward distance to the focus word (RandomLabel).

leftContextLabel - RandomLabel in left context at distance from the focus word, which can be used together with distance to calculate the weight.

Returns:

the context of the focus word modified according to the weighting scheme.

applyRightWeighting

public float[] applyRightWeighting(RandomLabel focusLabel,
                                   int distance,
                                   RandomLabel rightContextLabel)

Calculates the weight based upon the distance (in the right context) to the current label in the following manner: weight=(2^(1-distance to focus word)).

Specified by:

applyRightWeighting in class WeightingScheme

Parameters:

focusLabel - RandomLabel in focus, i.e. the focus word whose context vector should be modified with the weighted RandomLabel in right context.

distance - rightward distance to the focus word (RandomLabel).

rightContextLabel - RandomLabel in right context at distance from the focus word, which can be used together with distance to calculate the weight.

Returns:

the context of the focus word modified according to the weighting scheme.
