I would rather go to a restaurant with a 4.9 rating based on 1000 reviews than to a restaurant with one with a 5 rating based on 1 review. Makes me wonder: how would that feeling translate into a ranking function though.

I've used this approach in the past with great success:

All Evan Miller's posts on user ratings are excellent - https://www.evanmiller.org/ and search for "Mathematics of user ratings".

So what did you think of the article's approach to this issue?

Thanks for your comment, it made me do my homework. And apologies, I lazily viewed the first dozen rows and assumed that it was a simple high to low sort, and I was wrong. The author used https://en.m.wikipedia.org/wiki/Bayesian_average which answers my question. Cheers.

Author did not use a bayesian average but the Wilson score interval.

This is ranked by Bayesian Average: https://www.top-rated.online/countries/United+States/cities/...

This is correct. By the way I confirmed it's the same way reddit does its "Best" sorting
