Syntax Isn't Everything: NLP For Rubyists
summary
Demonstrates using the Google Cloud Natural Language API from Ruby (the google-cloud-language gem) to replace a 30-line emoji hack with three lines that return a score between -1 and 1 for sentiment; shows syntax tokens with head indices to extract subject/root/object and build ASCII sentence diagrams and Graphviz dependency graphs (via a Ruby graph gem) that correctly handle prepositional phrases; notes the first 5,000 API calls per month are free and that these demos are good for prototyping but not turnkey production systems.
