End-to-End NLP Sentiment Analysis Pipeline
01 — THE CHALLENGE
The problem.
Manual market research and media monitoring are highly inefficient, lacking scalable methods to quantify subjective bias and real-time sentiment from fragmented digital news sources.
02 — THE APPROACH
A thoughtful solution.
Architected an automated ETL and NLP pipeline using Python and BeautifulSoup to extract unstructured web data, deploying NLTK to quantify emotional polarity and subjectivity within an interactive Streamlit dashboard.
03 — BEHIND THE BUILD
How it came together.
The primary challenge was handling diverse and unstructured news sources in real-time. By implementing a robust ETL pipeline, we were able to standardize text data before passing it to the NLTK models. The outcome significantly reduced manual effort and provided clear, visualized insights into sentiment trends across different media outlets over time.
04 — THE RESULT
100% Automated NLP Pipeline
Eliminated manual news monitoring by instantly processing dynamic URLs, delivering real-time sentiment metrics and interactive data visualizations that accelerate data-driven decision-making.
Screens, systems,
