Description copied from class: WordRelatednessComparator

Return a relatedness value ESPECIALLY FOR LC_COMPARATOR!.

Specified by:

getRelatedness in class WordRelatednessComparator

Returns:

A value that indicates the relatedness of two words

getRelatedness

public double getRelatedness(double pathLength)

Returns:

A value that indicates the relatedness of two words

getRelatednessTrace

public java.lang.String[] getRelatednessTrace(java.lang.String word1,

Description copied from class: WordRelatednessComparator

Return a trace that illustrates the relatedness computation.

Specified by:

getRelatednessTrace in class WordRelatednessComparator

Returns:

A string array output, which is shown in the RelatednessGUI

getRelatedness

public double getRelatedness(java.lang.String word1,
                             java.lang.String word2)

Description copied from class: WordRelatednessComparator

Return a relatedness value.

Specified by:

getRelatedness in class WordRelatednessComparator

Returns:

A positive value that indicates the relatedness of two words. If one or both word have more than one sense the value that indicates the highest similarity is returned. If no relatedness value can be computed return 0.
