Build a Multilingual Text-Mining Dashboard for Hotel Reviews
Overview
What this challenge is about.
Build a multilingual hotel review pipeline with sentiment and aspect extraction, then deliver a Streamlit dashboard to earn your verifiable certificate.
The scenario
The consultancy (~20 staff) serves ~30 hotel groups across Indonesia, Thailand, Vietnam, and the Maldives; better local-language signal is a direct selling point.
The Brief
What you'll do, and what you'll demonstrate.
Replace a vendor sentiment API with an open-source multilingual text-mining stack that surfaces aspect-level signals at lower cost.
Earning criteria — what you'll demonstrate
- Build a multilingual NLP pipeline end-to-end
- Compare open-source sentiment models to a vendor API
- Extract aspect-level signals using a fine-tuned tagger
- Communicate multilingual NLP results to non-technical hotel managers
