getRelatedness

public double getRelatedness(java.util.ArrayList word1,
                             java.util.ArrayList word2,

Description copied from class: WordRelatednessComparator

Return a relatedness value ESPECIALLY FOR LC_COMPARATOR!.

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.

getRelatedness

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

Return a relatedness value.

Specified by:

getRelatedness in class WordRelatednessComparator

Returns:

A positive value that indicates the relatedness of two words. If no relatedness value can be computed return -1.0.

getRelatednessTrace

public java.lang.String[] getRelatednessTrace(java.lang.String word1,
                                              java.lang.String word2)

Return a trace that illustrates the relatedness computation.
