Using https://algorithmia.com/demo/rss or similar, we would like to be able to scan results from a news feed in real-time, displaying an overall negative/positive/neutral percentage for all results, the emotion associated with the article, highlighted negative/positive/neutral words that are color-coded, and if possible, display similar articles with sentiment analysis on the headlines. A nice to have would be the ability to include a chart that displays the positive/negative/neutral words for an article, maybe D3 or Google Charts? Mockups are available and CSS/SASS can be handled by us, we just need a developer to create the javascript, incorporate the APIs and provide raw html.
