Yelp Rating Prediction API

• http://br-yelp-predict-rating.herokuapp.com

I trained a model to predict the user’s review rating base on reviews on the Yelp dataset in the each specific category.

My API takes in a JSON string with "category" and "review". After sending the input to my API, it will respond with the predicted rating of the review.

When submitting a review, make sure to specify which category the review is for.

Example input:

{"category": "Auto Repair", 
 "review": "Service is the worst and the wait time is too long."}

The API will return a rating base on the category and review. Example Output:

{'Category': 'Auto_Repair',
 'Review': 'Service is the worst and the wait time is too long.',
 'Predict rating': 1}

Below is the list of categories used in the Yelp dataset:
