PRERONA: Mental Health Bengali Chatbot for Digital Counselling

Abstract

These three words “Human”, “Machine” and “Interaction” refer to the modern era of technology where researchers emphasized the interaction between computer machines and humans. We humans cannot confine ourselves to relying solely on human-based healthcare systems. The current era of digitization brings advances and additional opportunities for medical care, especially in general and clinical psychology. Existing chatbots such as Woebot, Wysa, Moodkit, etc. do not allow users to express themselves. However, our chatbot PRERONA allows the user space to talk about whatever they want along with it is intelligent enough to ask questions as well as answer questions. In our research work, we have presented a model named ‘PRERONA: Mental Health Bengali Chatbot for Digital Counselling’. PRERONA is designed to help depression struggling people especially for Bengali users who are lack attention and have none to talk about their problem. The main objective of this chatbot PRERONA is to give instant answers to questions and queries as well as to provide proper mental health care to Bengali’s in times of depression. Although our bot PRERONA is made only for Bengali users, we have it in multiple languages such as Bengali, English and Korean. In addition to that, we are using adaptive learning process. If the bot can not answer any questions, that will be recorded as well as added to that database later on for more accuracy. Natural Language Processing (NLP) is used here to successfully implement these languages. The complete structure of this chatbot and how it works are observed accurately throughout this research.
