Classification: CPC G | IPC G

Claim 9:
10. A server computer comprising:
one or more hardware processors; and
a computer-readable medium coupled with the one or more hardware processors, the computer-readable medium comprising instructions stored thereon that are executable by the one or more hardware processors to cause the server computer to perform operations comprising:
receiving a request for lookalike data, the request for lookalike data comprising seed data;
generating sample data from the seed data and from user data for a plurality of users, to use in a lookalike model training, by performing operations comprising:
generating a positive data sample from the seed data to use in the lookalike model training; and
generating a negative data sample from user data stored in a database to use in the lookalike model training;
training a lookalike model based on the sample data and user profile features for the plurality of users to generate a trained lookalike model;
generating a lookalike score for each user of the plurality of users in the user data using the trained lookalike model;
capturing a snapshot of social graph data for the plurality of users and determining at least one social graph feature;
generating a social graph score for each user of the plurality of users by comparing each user of the plurality of users to each user of the seed data based on the at least one social graph feature;
performing optimized ranking of the plurality of users based on the generated lookalike score for each user and the social graph score for each user;
generating a final lookalike score for each user of the plurality of users based on the optimized ranking; and
generating a list comprising a unique identifier for each user of the plurality of users and an associated final lookalike score for each unique identifier.
