Dialog systems (aka chatbots) are now key elements of digital channels in finance and banking environment. Dialog systems allows cost reduction, can increase customer satisfaction, and reduces errors. However, dialog technologies do not easily meet customer expectations. Machine to human conversation is a still a difficult aspect to handle, and recent advance in intent classification or dialog utterance handling using deep neural networks did not solve the question of robustness of dialog systems when deployed in production environment, with real human language interactions. In this communication, we will present innovative paraphrasing algorithms and dialog model generators we developed at National Bank of Canada to tackle this problem and improve robustness of dialog systems.
