The Yelp Dataset Challenge (https://www.yelp.com/dataset_challenge) releases data for a handful of cities each year. I'd like to analyze some cities from past years. Is this data archived anywhere?
It is my understanding that the dataset gets updated / extended every year. It started with Phoenix, then they added Las Vegas, Madison, Waterloo and Edinburgh, and so on, for a total of 11 cities by 2017.
Basically, this year's dataset should also include all cities from previous years.
