We have several chatbots that can answer user queries on a specific platform, and methods have been proposed for modified versions too, but there isn't good support for codemix language(say, Hinglish). We aim to build a language model for a conversation system. The final product would be a chatbot for bank conversations to fulfill the user queries and perform actions as per user requests in every way possible. The requests (or utterances) can be in codemix language, i.e., Hinglish. Later these requests are classified into intents, and after the process of slot filling, the database query is made. This complete task is accomplished in the form of a friendly conversation between the user and the chatbot.
