The Electricity Bill Inquiry Chatbot is a Natural Language Processing project that combines Response retrieval and Fallback handler, built with Flask. The project follows a clean, modular pipeline where text loading, processing, and presentation stay separated, making it easy to test, extend, and present. It showcases practical NLP techniques while producing a working, demo-ready application.
Traditional manual methods for this task are slow, inconsistent, and unable to scale as text data grows. Without an NLP-based approach built on Fallback handler and Flask, users cannot process, classify, or extract meaning from large amounts of text quickly, and there is no reliable way to evaluate the quality of the results.
This project applies NLP techniques through Response retrieval, orchestrated with Flask and Fallback handler. The pipeline is designed for quality and control, with preprocessing, feature extraction, and clear evaluation. It produces consistent, reusable results and can be adapted to related text tasks with minimal changes.

Modular text pipeline around Response retrieval and Fallback handler
Configurable preprocessing and model settings
Clear logging, metrics, and error handling
Clean interface for viewing results
Reusable components for related NLP tasks
Evaluation of output quality
The project is layered: the input layer loads and preprocesses text through Response retrieval; the processing layer applies NLP models with Flask and Fallback handler; and the output layer formats and presents results via Intent classifier. Shared configuration, logging, and evaluation modules support all layers, keeping the system robust and easy to extend.
