Method and apparatus for ranking responses of dialog model, and non-transitory computer-readable recording medium

An apparatus for ranking responses of a dialog model, the dialog model being trained based on a sample data set, the apparatus comprising:

• a memory storing computer-readable instructions;
• and
• one or more processors configured to execute the computer-readable instructions such that the one or more processors are configured to
• obtain, from the sample data set, at least one similar dialog whose content is semantically similar to content of a target dialog;
• obtain a probability of at least one target response generated by the dialog model when inputting the target dialog, and obtain a probability of a target response generated by the dialog model when inputting the similar dialog;
• statistically analyze, based on the probabilities of the respective generated target responses, scores of the target responses, the scores of the target responses being positively correlated with the probabilities of the target responses;
• and
• rank the target responses in a descending order of the scores.

A non-transitory computer-readable recording medium having computer-executable instructions for execution by a processing system, wherein, the computer-executable instructions, when executed, cause the processing system to carry out a method for ranking responses of a dialog model, the dialog model being trained based on a sample data set, the method comprising:

• obtaining, from the sample data set, at least one similar dialog whose content is semantically similar to content of a target dialog;
• obtaining a probability of at least one target response generated by the dialog model when inputting the target dialog, and obtaining a probability of a target response generated by the dialog model when inputting the similar dialog;
• statistically analyzing, based on the probabilities of the respective generated target responses, scores of the target responses, the scores of the target responses being positively correlated with the probabilities of the target responses;
• and
• ranking the target responses in a descending order of the scores.
