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.
