System and method for synthetic text generation to solve class imbalance in complaint identification

Abstract

A computer based system and method for synthetic text generation includes a processor. The processor implements a text style transfer algorithm to first input data to generate complaints data from non-complaint emails data associated with a plurality non-complaint emails. The processor converts the plurality of non-complaint emails into a first set of complaint emails based on implementing the text style transfer algorithm and implements a text generation model algorithm to second input data to generate a second set of complaint emails from a plurality of complaint emails. The processor also generates a set of synthetic complaint emails based on the generated first set of complaint emails and the second set of complaint emails; trains a model based on the generated synthetic complaint emails; and applies the trained model to a new set of emails to resolve class imbalance in automatic complaint identification from the new set of emails.
