What's Love Got To Do With It? Ruby and Sentiment Analysis
summary
Shows a concrete pipeline: a Ruby app that fetches headlines via News API, sends the concatenated text to IBM Watson NLU for sentiment and emotion scoring, and replies over WhatsApp using the Nexmo Messages API. Demonstrates responses like document sentiment and emotion percentages (example sentence returns ~97% positive, demo returns ~70% joy for “Ruby”), notes free‑tier/API keys and region‑bound Watson URL, and the prototype runs end‑to‑end in the live demo.
