Abstract:
1. A computer-implemented method for calibrating a probability of spam, the method comprising: determining, using one or more processors, a spam score for each of a plurality of business listings; dividing each of the plurality of business listings into a plurality of buckets based on the spam score for each listing; determining, using the one or more processors, an average score for a set of business listings in each bucket; determining a ratio of spam listings to legitimate listings for the set of business listings in each bucket; determining, using the one or more processors, a closed-form function that maps the average score for each bucket to the ratio for each bucket, such that a first axis of the closed-form function is the average score and a second axis of the closed-form function is the ratio; and determining, using the one or more processors, a probability that a business listing is a spam listing by mapping a spam score for the business listing to the closed-form function.
