Method, device, and computer program product for user behavior prediction

A device implemented at a server, comprising:

• a processor;
• and
• a memory having computer-executable instructions stored therein, wherein the computer-executable instructions, when executed by the processor, cause the device to execute actions comprising:
• receiving behavior prediction information of a target user from a client;
• generating recommendation information about a group of items based on feature information of the group of items through a second item embedding engine in the server;
• determining, based on the behavior prediction information of the target user and the recommendation information about the group of items, a target item recommended for the target user from the group of items;
• and
• sending information about the target item to the client.

A computer program product tangibly stored in a non-transitory computer-readable medium and comprising machine-executable instructions, wherein the machine-executable instructions, when executed, cause a machine to perform the steps of:

• receiving, at a server, behavior prediction information of a target user from a client;
• generating, by a second item embedding engine in the server, recommendation information about a group of items based on feature information of the group of items;
• determining, based on the behavior prediction information of the target user and the recommendation information about the group of items, a target item recommended for the target user from the group of items;
• and
