I'm pretty sure if you gave ChatGPT the old and new versions of the listing, it would have a 99%+ accuracy when answering the question, "are these for the same product?" So they could just run each change through something like that, and wouldn't have to write any custom heuristics.

I'm pretty sure any of a million simpler edit distances could tell you if a product listing was substantially changed.

Of course, though perhaps with slightly lower accuracy. Either way, my point was that it's far from an unsolvable problem; it can be trivially solved with existing tools.
