Antonyms are not at all straightforward, in my view. Some other users
might think the antonym of "serviceman" was "armed robot", on the
grounds that a machine is the opposite of a human; others might even see
the opposite as being "servicewoman"!

I prefer this approach too. Thus it leaves the flexibility for thesaurus
managers to treat some antonyms as pseudo-synonyms and others as
associatively related preferred terms, according to the merits of each
