Pandemic-Aware Local Recommendation

Code Details

"sample_LP.py": Sample code for the proposed linear programming approach

INPUTS: All the details required for one instance of ranking (***note (lambda_1+lambda_2) <= 1)
    E (array) = current exposure of businesses in an array
    capacity (array) = safe capacities of businesses in an array
    relevances (array) = rele
    k (int) = size of the recommendation
    beta_fraction (float) = beta/beta_max (this ultimately decides how much of exposure we are trying to guarantee for every business)
    lambda_1 (float) = weight (fraction) for the sustainability term in the objective
    lambda_2 (float) = weight (fraction) for the safety term in the objective
    
OUTPUT: 
    reco = A k-ranked list of businesses
    E = updated exposure of businesses

Dataset Information

List of files

Customer_Choice_Survey.csv
NYC_Google.csv
NYC_Yelp.csv
SF_Google.csv
SF_Yelp.csv

Field Details in Each File

  • "Customer_Choice_Survey.csv": Each respondent was first asked some basic details. Then 7 rounds of ranking questions were asked. In each round, they were given a list of 10 restaurants with random combinations of rating, distance and cuisine. They were asked to rank top 5 one-by-one out of those 10 provided. This becomes evident from the question titles provided the file.
  • "NYC_Google.csv" and "SF_Google.csv": Local recommendations received on Google Local (Google Maps) for different customer locations in New York and San Francisco.
"customer_location": location of the customer where she gets recommendation
"rank": rank of the restaurant in the recommended list
"id": restaurant's id internal to google
"latitude": latitude of restaurant's geographic coordinates
