(Most frequent noun sense inappropriate)

“Chair” is morphologically ambiguous –
can be either a noun or a verb.  NL-Soar tries both trees,
But the syntax module rejects “chair” as a verb (green X on left).
This causes semantic module to throw out all the verb-classes which include a sense of the word “chair” (green X on right through v-social)

This still leaves two noun-classes: n-artifact and n-person.
N-artifact is more common, and is tried first.
But v-body rejects n-artifact as a subject, so it fails constraint.
NL-Soar then tries n-person (e.g., dept. chair), which succeeds.
