getVectorCreatorName

public String getVectorCreatorName()

Description copied from interface: VectorCreator

Returns the name of the direct confirmation measure which is used to create the vectors.

Returns:

createVectors

public SubsetVectors[] createVectors(String[][] wordsets,
                                     SegmentationDefinition[] definitions,
                                     SubsetProbabilities[] probabilities)

createVectors

public SubsetVectors createVectors(int wordsetLength,
                                   SegmentationDefinition definition,
                                   SubsetProbabilities oneOneAndSelfProbabilities,
                                   SubsetProbabilities probabilities)

Creates the vectors for a single wordset.

Parameters:

wordsetLength - the length of the wordset

definition - the definition of the segmentations that will be copied into the created subset vector definition

oneOneAndSelfProbabilities - this probabilities instance should contain the segmentation of the OneOneAndSelf class for the given word set. Note that although it is a probabilities instance probabilities instance, its probabilities will be internally overridden with the next probabilities parameter. Note this parameter is mainly used to reuse the generated OneOneAndSelf segmentation for a given set of wordsets.

probabilities - the probabilities for the given word set.

Returns:

subset vectors that comprise the vectors for the given wordset length based on the given probabilities and the direct confirmation measure of this class (calculation). The subset vector instance will also contain the given segmentation information as well as the given probabilities.
