PubNub Launches Sentiment Analysis Machine to Analyze Twitter’s Feelings on 2018 Midterm in Realtime

Powered by PubNub, Amazon Comprehend, and Initial State, the realtime dashboard delivers up-to-millisecond analysis based on filtered keywords and topics.

San Francisco, CA – October 23, 2018 – PubNub, the company behind the world’s leading realtime Data Stream Network (DSN), today announced the launch of its Sentiment Analysis Machine to analyze and gauge how Twitter users feel about the upcoming 2018 Midterms. The new application filters tweets based on a wide-variety of Midterm-related keywords, like #2018Midterm, #election, #bluewave, #redwave. It then gauges the level of negativity/positivity contained within that tweet and plots the aggregated results on a live-updating dashboard.

The Sentiment Analysis Machine uses the PubNub Realtime Twitter Firehose to collect and filter a constant stream of tweets, and utilizes Amazon Comprehend through PubNub Blocks to serverlessly deliver the analysis of sentiment. The live, realtime dashboard is powered by Initial State. All messaging happens through the PubNub Data Stream Network, and each tweet is factored into the outcome in under a second.

The Sentiment Analysis Machine is the latest showcase of PubNub’s ability both to serverlessly run analysis on massive streams of data and visualize that data in realtime on a live dashboard. Earlier, PubNub and Initial State launched a similar application to see how Twitter users felt about Donald Trump and can now analyze the sentiment of current trends such as the 2018  Midterms.

“There are thousands and thousands of ways to analyze and predict how the Midterms will go,” said Simon Jones, VP of Marketing at PubNub. “FiveThirtyEight, Nate Silver’s statistical analysis website, has daily forecasts around the upcoming Senate, House, and Gubernatorial races. And while FiveThirtyEight’s analysis focuses on national and district data sets, PubNub’s Sentiment Analysis Machine focuses on the emotional side of the Midterms.”

PubNub customers have also harnessed this functionality to build realtime dashboards into their products. For instance, INSTEON, a home automation company, uses PubNub to empower their customers to monitor and control smart devices in their home. And ClassDojo enables teachers, parents, and administrators to track points and performance of students in realtime.
