The score calculation means 82 calculates 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 means 83 estimates 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data linkage system, learning device, and estimation device","description":"The data linkage system 90 includes a learning device 70 which 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 ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11977583","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
