context is everything. "A violent mob requested a demonstration from the councilmen. The councilmen refused the permit, because they feared the violence." I suspect, grammar begets normalization, with primary and secondary keys just like in relational databases. People are just not very good at it. EG. I'd contest the consistency of those 1000 grammar rules. Point in case, the word "violence" needs the definite article, because violence is an abstract concept (which the parent missed). All the while the indefinit and definit articles serve other purposes, eg. the quantifiers from logic (for all, there exists) which are at odds with the naive countability of the violence. So Language is ambiguous, NLP is done probabilistic and thus is hard with at least exponential complexity. Edit: What I mean is, the problem here is contraction omitting context. Of course databases worked before relational databases, but sometimes you really want the third normal form.
