Recommendation information pushing method, server, and storage medium

A server, comprising:

• a memory storing instructions;
• and
• a processor coupled to the memory and, when executing the instructions, configured for:
• obtaining a meta path that connects a candidate user and a target user in a heterogeneous information network, the meta path comprising a connection between the candidate user and a candidate recommendation-object and having an attribute value;
• obtaining a user similarity between the target user and the candidate user relative to the meta path;
• estimating an attribute value of a connection between the candidate recommendation-object and the target user according to the attribute value of the connection between the candidate user and the candidate recommendation-object, an attribute value constraint condition of the meta path, and the user similarity;
• and
• sending recommendation information of the candidate recommendation-object to a terminal corresponding to the target user when the estimated attribute value meets a recommendation condition.

A non-transitory computer-readable storage medium containing computer-executable instructions for, when executed by one or more processors, performing a recommendation information pushing method, the method comprising:

• obtaining a meta path that connects a candidate user and a target user in a heterogeneous information network, the meta path comprising a connection between the candidate user and a candidate recommendation-object and having an attribute value;
• obtaining a user similarity between the target user and the candidate user relative to the meta path;
• estimating an attribute value of a connection between the candidate recommendation-object and the target user according to the attribute value of the connection between the candidate user and the candidate recommendation-object, an attribute value constraint condition of the meta path, and the user similarity;
• and
• sending recommendation information of the candidate recommendation-object to a terminal corresponding to the target user when the estimated attribute value meets a recommendation condition.
