Abstract
The data linkage systemincludes a learning devicewhich generates a score function, which is a function that scores proximity between a user with an action history in a first domain and a user with an action history in a second domain, and an estimation devicewhich estimates a user matched in the first domain and the second domain. The score calculation meanscalculates a score for a pair of users who have an action history in a first domain and an action history in a second domain using a score function. The matching meansestimates the same user as the user in the first domain from among the users in the second domain based on magnitude of the calculated score.
