How can the summaries and statements linked to particular references be identified?
I pretty sure this does not exist.  It would require a level of sophisticated text parsing that has not been developed by computers.  After all, not all statements that the earth is round are going to phrased the same way, and for such a tool to be useful, it would be necessary to identify statements with the same semantic meanings.  This is not possible with the current language processing techniques; it would be huge advance if a computer could reliably parse and identify logically equivalent statements.  So you are not going to find what you are looking for.
