The Pharmacy Medicine Guide Chatbot is a Natural Language Processing project that combines Entity extractor and Chat web interface, built with Rasa / ChatterBot. 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 Chat web interface and Rasa / ChatterBot, 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 Entity extractor, orchestrated with Rasa / ChatterBot and Chat web interface. 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.

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 Entity extractor; the processing layer applies NLP models with Rasa / ChatterBot and Chat web interface; and the output layer formats and presents results via Training data builder. Shared configuration, logging, and evaluation modules support all layers, keeping the system robust and easy to extend.
