LogoI’ve been invited to write a few words about a Chrome Extension I’ve made that uses the Semantria API to analyze sentiment on any webpage on-the-fly. It’s a simple extension where, once installed, you’ll be able to highlight any text on any page and extract all the Entities, Themes, Phrases, Topics and the Sentiment Score related to the whole text or for each Entity, Theme, Phrase or Topic found. I’d like to thank Wilson and the Semantria guys for this opportunity.
