|Example #3: The crevasse yawned.
(Most frequent verb sense inappropriate)
|There is only
one sense for crevasse in WordNet, and it belongs to n-object. This doesn’t work as a subject of body
verbs, so the verb sense fails (matching with no subjects and failing to fill
its external role).
|There is another
sense of yawn (“be open, gape, yaw”) which does fit with natural objects, and
this sense matches.
