CONTACT RECOMMENDATIONS BASED ON PURCHASE HISTORY

摘要

Contact recommendations based on purchase history are described. A system creates a directed graph of nodes in which at least some of the nodes are connected by directed arcs, wherein a directed arc from a first node to a second node represents a conditional probability that previous users who purchased a first contact also purchased a second contact. The system identifies a set of contacts purchased by a current user. The system estimates a prospective purchase probability based on a historical probability that previous users purchased a specific contact and a related probability that previous users who purchased the specific contact also purchased a contact in the set of contacts, for each candidate contact. The system outputs a recommendation for the current user to purchase a recommended candidate contact based on a corresponding prospective purchase probability.

主权项

1. A system for contact recommendations based on purchase history, the apparatus comprising:
one or more processors; and a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to:
create a directed graph of a plurality of nodes in which at least some of the plurality of nodes are connected by a plurality of directed arcs, wherein a directed arc from a first node to a second node represents a conditional probability that previous users who purchased a first contact also purchased a second contact;identify a set of contacts purchased by a current user;estimate a prospective purchase probability based on a historical probability that previous users purchased a specific contact and a related probability that previous users who purchased the specific contact also purchased a contact in the set of contacts, for each candidate contact; andoutput a recommendation for the current user to purchase a recommended candidate contact based on a corresponding prospective purchase probability.
