The Multilingual Sentiment Analysis System is a Natural Language Processing project that combines Real-time fetch module and Lexicon-based scoring, built with Streamlit UI. 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 Lexicon-based scoring and Streamlit UI, 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 Real-time fetch module, orchestrated with Streamlit UI and Lexicon-based scoring. 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.

Evaluation of output quality
The project is layered: the input layer loads and preprocesses text through Real-time fetch module; the processing layer applies NLP models with Streamlit UI and Lexicon-based scoring; and the output layer formats and presents results via Aspect extraction. Shared configuration, logging, and evaluation modules support all layers, keeping the system robust and easy to extend.
