The Rule-Based FAQ Bot is a Natural Language Processing project that combines Dialogue manager and Training data builder, built with TF-IDF retrieval. 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 Training data builder and TF-IDF retrieval, 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 Dialogue manager, orchestrated with TF-IDF retrieval and Training data builder. 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 Dialogue manager and Training data builder
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 Dialogue manager; the processing layer applies NLP models with TF-IDF retrieval and Training data builder; and the output layer formats and presents results via Entity extractor. Shared configuration, logging, and evaluation modules support all layers, keeping the system robust and easy to extend.
