Zomato to show separate restaurant ratings for delivery and dining

Firm also working on weeding out fake or paid reviews using machine-learning algorithms

Food aggregator Zomato said on Thursday that it has revised its rating system for restaurants on the app, and will now show separate ratings for delivery and dine-in. 

The firm also declared its ratings algorithm its "most precious intellectual property" and will not disclose it to anyone. 

The delivery ratings will be visible in red while dine-in ratings will show as black stars.
