Can any automatic citation checkers infer about the validity of the content?
Rather than just formatting?
I.e. if one writes something like
"abc has been studied by XYZ (2015, p. 25). In this study they made an observation about abc with 45% accuracy.".
Then the checker would check, whether the source XYZ actually talks about abc and whether at p. 25 of the linked document there is mention of this 45% accuracy thing.
