Smart FAQ Assistant

Project Overview

Smart FAQ Assistant is a web-based chatbot developed to answer frequently asked questions related to Artificial Intelligence, Machine Learning, Python Programming, and Computer Science fundamentals.

The system uses Natural Language Processing techniques to understand user queries and identify the most relevant answer from a predefined knowledge base. Instead of relying on exact keyword matching, the chatbot compares the user's question with stored FAQ entries and returns the closest matching response.

The project was developed as part of the Artificial Intelligence Internship program and demonstrates the practical use of NLP, text vectorization, similarity matching, and interactive web application development.

Problem Statement

Users often need quick answers to common technical questions. Searching through documentation or multiple web pages can be time-consuming. This project provides a simple interface where users can ask questions and receive instant responses from a curated FAQ database.

Objectives

  • Build an intelligent FAQ-based chatbot.
  • Apply Natural Language Processing techniques.
  • Implement similarity-based question matching.
  • Create a user-friendly web interface.
  • Provide instant responses from a structured knowledge base.

Features

  • Interactive web interface built with Streamlit.
  • FAQ-based question answering system.
  • Supports topics related to AI, Machine Learning, Python, and Computer Science.
  • Uses TF-IDF vectorization for text representation.
  • Uses Cosine Similarity to identify the best matching question.
  • Maintains chat history during the session.
  • Displays confidence score for matched responses.
  • Clear Chat functionality.

Working Process

Step 1: User Input

The user enters a question through the Streamlit interface.

Step 2: Text Processing

The entered question is converted into a numerical representation using TF-IDF Vectorization.

Step 3: Similarity Calculation

Cosine Similarity is used to compare the user's question with all questions stored in the FAQ database.

Step 4: Best Match Selection

The system identifies the FAQ with the highest similarity score.

Step 5: Response Generation

If the similarity score is above the predefined threshold, the corresponding answer is displayed. Otherwise, the chatbot informs the user that no suitable answer was found.
