This project seeks to derive a score profile for restaurants across certain aspects in hopes to provide some insight as to how each restaurant can improve their business. The aspects are derived via topic modelling using LDA and we're using business reviews from the Yelp dataset to train our LDA model with.
As there is a large amount of reviews from the dataset, we are only zooming in to reviews for restaurants located in Las Vegas for computational efficiency since this subset contributes to the greatest proportion of points in the dataset.
The yelp dataset can be obtained from here, and experiments were conducted primarily on Google Colab as well. We only require two of the datasets from Yelp, namely business.json and review.json.
We have only 3 files which focus on different actions:
-
yelp_business_filtering.ipynb: Handles the filtering of businesses to extract restaurants within Las Vegas based on the propertiescityandcategories -
yelp_review_filtering.ipynb: Handles the filtering of reviews to extract all reviews related to restaurants in Las Vegas based onbusiness_id. -
yelp_lda_model.ipynb: Handles the preprocessing and actual training of the LDA model based on the filtered reviews, as well some analysis on the results.
