How We Associate Corresponding Apps In Apple iTunes And Google Play

The article details a three-step automated process to match apps between iTunes and Google Play.
First, potential candidates are found via exact name, individual word, and bigram searches.
Second, text comparison scores app name, publisher name, and support URL domains, with a blacklist for common domains.
Third, image analysis uses perceptual hashing to compare icons after standardization.
Perfect text scores skip image analysis; otherwise, the highest-scoring candidate with a similar icon is chosen.
The system has been refined and handles exceptions like Facebook.
