1. An electronic apparatus comprising:
at least one memory storing instructions, a plurality of chat-bots for responding to a plurality of questions, a question classification model trained to identify a chat-bot among the plurality of chat-bots for responding to an input question, and information of a plurality of domains respectively corresponding to the plurality of chat-bots; and
at least one processor configured to execute the instructions to:
input the input question into the question classification model, the question classification model outputting a first chat-bot among the plurality of chat-bots for responding to the input question,
through the question classification model, identify a first domain among the plurality of domains that is related to an input text included in the input question,
based on the information of the plurality of domains respectively mapped to the plurality of chat-bots, select the first chat-bot among the plurality of chat-bots that is mapped to the first domain,
acquire a first response for the input question, through the first chat-bot,
based on the first response comprising information of a function of the electronic apparatus that can be performed at the electronic apparatus, generate a generated question requesting to perform the function,
input the generated question into the question classification model, the question classification model outputting a second chat-bot corresponding to a domain of generated text included in the generated question among the plurality of domains respectively corresponding to the plurality of chat-bots for responding to the generated question,
acquire a second response for the generated question, through the second chat-bot, and
provide a combined response to the input question, based on the first response and the second response.
