Method, device, and computer program product for determining node of decision tree

An electronic device, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and having instructions stored therein, wherein the instructions, when executed by the at least one processor, cause the electronic device to perform actions comprising:
• determining multiple feature representations of multiple modals corresponding to input information;
• generating a multi-modal feature representation by combining the multiple feature representations of the multiple modals;
• determining a target path in a decision tree that is associated with the multi-modal feature representation, the decision tree comprising multiple nodes;
• and
• determining, in the target path based on the multi-modal feature representation, a target node associated with the input information and used to indicate a question or an answer.

A computer program product comprising a non-transitory computer-readable storage medium storing machine-executable instructions which, when executed by a machine, cause the machine to perform actions comprising:

• determining multiple features of multiple modals corresponding to input information;
• generating a multi-modal feature representation by combining the multiple features of the multiple modals;
• determining a target path in a decision tree that is associated with the multi-modal feature representation, the decision tree comprising multiple nodes;
• and
• determining, in the target path based on the multi-modal feature representation, a target node associated with the input information and used to indicate a question or an answer;
• wherein the machine comprises an electronic device that includes at least one processor and memory coupled to the at least one processor, and further wherein the actions are performed by the electronic device.
