getRelatedness

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

Return a relatedness value.

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.
