Question

Develop a chatbot that can hold a non-trivial conversation with users.

The chatbot should have more than one characters.
Task specific e.g. Airline ticket booking agent
General chatter; cheerful , grumpy etc
You will design your code based on OOP principals, modularize it, define appropriate classes, meaningful variable/class/function names.

Required functions:

1. Memory: Chatbot should recognize a user (using username etc) and load/save the chat history of a user. It should be able to remember key information (and reply correctly when asked) about user, e.g name, age, hobbies, etc
2. Character. The chatbot should be able to change its character on demand upon user request.

Answer 1

Building a conversational chatbot that exhibits diverse characters and handles tasks like airline ticket bookings involves using OOP principles for modularizing code. Classes should be designed for managing user data and chatbot personalities, allowing memory functions and dynamic personality switching to create an engaging user experience.

Step-by-step explanation:

Developing a Conversational Chatbot with OOP Principles

In designing a chatbot that can hold a conversation with different characters and complete task-specific operations like airline ticket booking, it is essential to employ Object-Oriented Programming (OOP) principles. The design should include modularization, where different aspects of the chatbot's functionality are encapsulated within appropriate classes. For instance, a User class can manage user details and history, while a ChatCharacter class can handle the personality traits of the chatbot, enabling it to switch between cheerful, grumpy, and other moods.

To satisfy the memory function, the User class should have methods to recognize a user by a unique identifier like a username, and maintain a chat history in a data structure, such as a list or a dictionary. This class should also store key personal information that the chatbot will remember and reference in conversations. The ChatCharacter class should allow dynamic changes to the chatbot's current mood and responses, upon user interaction. The incorporation of these features mandates the use of meaningful variable, class, and function names to enhance code readability and maintainability.

Key Functions for a Conversational Chatbot

• Memory: Load and save chat history, remember key user info.
• Character: Toggle between different chatbot personalities.

Implementing these functionalities allows the chatbot to offer a more personalized and engaging experience, akin to chatting with a human representative. The use of OOP principles ensures that the system is scalable and can evolve to handle additional tasks or support more complex conversations in the future.
