  When using a third language to construct a bilingual dictionary, it is
necessary to discriminate equivalencies from inappropriate words derived as a
result of ambiguity in the third language. We propose a method to treat this by
utilizing the structures of dictionaries to measure the nearness of the
meanings of words. The resulting dictionary is a word-to-word bilingual
dictionary of nouns and can be used to refine the entries and equivalencies in
published bilingual dictionaries.
