This application discloses a method, storage medium, and program product for determining the
semantics of a problem, relating to the field of
artificial intelligence technology. The method includes: acquiring user questions that do not match within a preset time period to obtain a problem to be maintained, and acquiring a target standard question corresponding to the problem to be maintained; acquiring tags matching the problem to be maintained from a tag
library to obtain a candidate tag set, and constructing a first prompt word based on a generation instruction, the problem to be maintained, and the candidate tag set. The generation instruction is used to
mask a preset vocabulary according to the candidate tag set and generate at least two semantic expressions for the problem to be maintained; inputting the first prompt word into a
target expression generation model to generate a candidate semantic expression set corresponding to the problem to be maintained; determining the target semantic expression from the candidate semantic expression set, and adding the target standard question and the target semantic expression to a problem matching
library. This improves the efficiency and accuracy of determining the
semantics of a problem and enhances the accuracy of the business service platform's responses.
