That is, whoever controls the corpus of "established true facts" controls the determination of whether something is or is not fake news. Which probably gets us to competing corpuses (corpi?) of "established true facts", run by those who push competing meta-narratives. Which looks rather similar to the current situation...
Exactly so. The operator of the machine gets to control what it is told is 'true' and 'false'. That said, assuming a nominally good actor and an inability to have people process every article, this process provides a means to quantitatively analyze for coherence with your controlled corpus.
"Quantitatively analysing the coherence of a controlled corpus," is not exactly a solution to fake news, although it's probably useful for a few other things.
It certainly helps a lot due to the fact that today you can't be expected to practically sift over all the available information yourself because there's simply too much of it.
If we had a system like this that worked, we could at least leverage it to be able to quantify the coherence of a much larger set of inputs and with many controlled corpora at once.
