Improve User Experience with Professional Greetings and Responses

D

To add professional greetings and other responses to make the QnA Maker bot more user friendly, you need to add chit-chat. The correct answer is D.

Explanation of each answer option:

A. Increasing the confidence threshold of responses: This option is not related to adding professional greetings and other responses to make the bot more user friendly. Confidence threshold is a setting that determines the minimum score that a response must have to be returned by the bot. Increasing it would make the bot more conservative in its responses and may even lead to missing out on some correct responses.

B. Enabling active learning: This option is also not directly related to adding professional greetings and other responses to make the bot more user friendly. Enabling active learning would allow the bot to learn from user interactions and improve its responses over time, but it wouldn't add the specific type of responses requested in the question.

C. Creating multi-turn questions: This option is related to improving the bot's ability to handle complex queries that require multiple questions and answers. However, it does not specifically address the need for professional greetings and other responses to make the bot more user friendly.

D. Adding chit-chat: This option is the correct answer. Chit-chat refers to small talk or casual conversation that is not directly related to the main purpose of the bot. Adding chit-chat can make the bot more engaging and user-friendly, and can help establish a rapport between the bot and the user. For example, the bot could greet the user with a friendly message or ask how their day is going before proceeding with the main purpose of the conversation.

In summary, to add professional greetings and other responses to make the QnA Maker bot more user friendly, you should add chit-chat.
