1. A method of determining a session duration time of a chatbot, the method comprising:
outputting a response message regarding an input message of a user;
determining a default session time during which a session is maintained based on a difficulty level of the output response message;
determining an additional session time based on conversation history information through the chatbot prior to outputting of the response message;
waiting for an input of an additional message of the user during a session duration time, which is a sum of the default session time and the additional session time; and determining an end of the session based on whether the additional message is input, and
wherein the determining of the default session time comprises: obtaining a label value of the difficulty level by applying the response message to a deep neural network model as an input; and determining a session time mapped to correspond to the obtained label value as the default session time.
