I thought it was pretty obvious that it was generated automatically based on how much it depends on the exact keywords you search for. I think that given a certain set of products, the algorithm actually seems to do a pretty good job of making a recommendation for the best product out of the set based on the ratings or whatever it looks at, but the bigger problem is that if you aren't searching for exactly the right keywords the choice of the best product becomes completely meaningless, and blindly tacking on the "amazon's choice" recommendation obscures the fact that your search is too narrow to provide a meaningful recommendation in the first place. (I'm sure there is some filtering based on ratings but because of how common fake reviews are, if you're looking at niche products they'll almost all have fairly high ratings anyway.) It's probably better to not provide a recommendation than to recommend a bad product, so maybe they should try to narrow it down to more common categories.
