What exactly is a fact? There's no easy answer to that question, particularly with natural rather than formal languages. 'Facts' and statements depend on context. The meaning of a natural language statement usually is derived from these layers building on each other:
- syntax (the structure of a sentence)
- semantics (the isolated meaning of a sentence)
- pragmatics (the meaning of a sentence in context)
Anaphora (references to previous sentences or concepts) can be particularly nasty in this context.
Depending on the task at hand chunk parsing could be a good first take at finding relevant phrases from unstructured textual data. There are numerous libraries to accomplish that, for English and other Indo-European languages at least.

I am fine to start with high precision and low recall, I think. Need to try in action and see if relevance of domain specific search and automatic validation can be improved with this approach.
