Researchers at the University of Maryland’s Robert H. Smith School of Business say they can use Yelp reviews to predict a restaurants chance of success or failure. I know what you’re thinking, it doesn’t take a mathematician or linguistics expert to know that a restaurant with bad reviews is going to close down sooner than later. But there’s more to this story.
The researchers analyzed Yelp reviews for 2000 open restaurants in Washington DC and 450 restaurants that had closed in the past few years. That gave them more than 130,000 reviews with a total of 15 million words.
They then used a text reader to scan and flag certain words in several different buckets.
