There is no need to regard language as an ideal object to find semantic
propositions. You can try and device a robust approach that extracts
some sort of core semantic representation, this is feasible with the
current technology.
This is the central idea in answer extraction and question answering
systems like ExtrAns and AnswerFinder. These systems find the sentences
with highest predicate overlap with the predicates generated by the
question. And you guess right, this list of predicates is automatically
produced from any text sentence or question.
For more information you can have a look at:

AnswerFinder's Web page is still very preliminary, I'll add more
information shortly.
