This project involves building an AI Chatbot with Natural Language Processing (NLP) capabilities, designed to interact with users conversationally. The chatbot will assist users in obtaining information, answering queries, and providing customer support across various platforms, including web and mobile interfaces.
The "AI Chatbot with NLP" project aims to develop a scalable and efficient API that allows users to engage with the chatbot through natural language, facilitating smooth interactions and enhancing user experience. This API will support multiple front-end applications, integrating seamlessly with existing systems.
In today’s digital landscape, AI-driven interactions have become essential for businesses aiming to provide efficient customer service and engagement. This project will create a chatbot that enhances user satisfaction and operational efficiency.
User Interaction Overview
User Registration and Authentication
Sign Up: New users can create an account by providing an email and password. They will receive a confirmation email to verify their account.
Login: Registered users can log in using their email and password. The API will support
multi-factor authentication (MFA) for enhanced security.
Conversational Interaction
Text Input: Users can interact with the chatbot via text input, asking questions or seeking assistance.
Contextual Understanding: The chatbot uses NLP to understand user intent and context, providing relevant responses.
Knowledge Base Integration
FAQs and Help Center: The chatbot can access a knowledge base to provide instant answers to frequently asked questions.
Feedback and Learning
User Feedback: Users can provide feedback on responses to improve the chatbot's accuracy and relevance.
Learning Mechanism: The chatbot will learn from interactions to enhance its performance over time.
Analytics Dashboard:
Interaction Metrics: Administrators can view metrics related to user interactions, satisfaction scores, and common queries.
Objectives
Allow users to sign up, log in, and manage their accounts securely.
Enable users to interact with the chatbot using natural language.
Facilitate access to information and customer support through the chatbot.
Provide administrators with analytics to monitor performance and user engagement.
Ensure robust security and user data protection.
Functional Requirements
User Management
Sign Up: Users can create an account using their email and password.
Login: Users can authenticate using their email and password.
Profile Management: Users can update their profile information.
Conversational Interaction
Chat Interface: Users can interact with the chatbot through a user-friendly chat interface
NLP Processing: The chatbot processes user input to understand intent and context.
Knowledge Base Integration
Access FAQs: The chatbot retrieves information from a knowledge base to answer common queries.
Dynamic Updates: The knowledge base can be updated by administrators as new information becomes available.
User Feedback: Users can rate the chatbot's responses to help improve accuracy.
Learning Mechanism: The chatbot learns from interactions to refine its understanding and responses.
Analytics Dashboard
View Metrics: Administrators can access metrics related to user interactions and satisfaction levels.
Common Queries: A report on the most frequently asked questions can be generated for analysis.
Non-Functional Requirements
Scalability: The API should handle a growing number of users and interactions.
Performance: The API should have a fast response time for user queries.
Security: Implement authentication and authorization mechanisms to protect user data.
Reliability: The API should be highly available and handle failures gracefully.
Usability: The chatbot should be easy to use, providing a seamless experience for users.
Use Cases
User Sign Up and Login: New users create an account, and existing users log in.
Chat Interaction: Users engage with the chatbot to seek information or assistance.
Access Knowledge Base: Users query the chatbot for FAQs and support.
Provide Feedback: Users give feedback on chatbot responses to enhance learning.
View Analytics: Administrators access interaction metrics and common queries.
User Stories
