“Not that difficult”? Can you elaborate? Because I think it’s nearly insurmountable. Is the sentence “Meagan Smith graduated magma cum laude from Northwestern’s business program in 2004” PII? How about if another part of the corpus says “M. Smith had a promising career in business after graduating with honors from a prestigious school, but an unplanned pregnancy caused her to quit her job in 2006”? Does it matter if it’s from fiction? What if the fiction it comes from uses real people? Or if there might be both real and fictional Meagan Smiths? And how so you process that kind of thing at the scale of billions of documents? This is a very hard problem, especially at scale.
