Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 12:
13. A non-transitory computer readable medium that stores a set of instructions that is executable by at least one processor of a computer to cause the computer to perform a method, the method comprising:
extracting user behavior data associated with the user inquiry from collected user behavior data as candidate user behavior data;
selecting, from the candidate user behavior data, candidate user behavior data that is contained in a target behavior data set;
inputting the selected candidate user behavior data into a classifier model that is a neural network model trained based on training data; and
predicting an inquiry category associated with the user inquiry using the classifier model based on the inputted selected candidate user behavior data,
wherein the classifier model is trained by:
collecting a plurality of training user inquiries and training user behavior data corresponding thereto;
extracting user behavior data associated with each of the plurality of training user inquiries from the collected training user behavior data as training candidate user behavior data;
scoring, by using a data-driven method, the training candidate user behavior data corresponding to each of the plurality of training user inquiries;
selecting, from the scored training candidate user behavior data, target behavior data based on a set condition; and
obtaining the classifier model by training, based on the plurality of training user inquiries and the target behavior data.
