‘Mood meter’ says Obama won debate on Twitter

President Barack Obama kept Twitter users happier than Republican presidential nominee Mitt Romney through most of last night’s debate, according to a Silicon Valley company’s analysis.

NetBase, a Mountain View-based firm that “delivers the enterprise social intelligence platform that global enterprises use to monitor, understand, and engage with customers in real time,” has created a Mood Meter: a dial updated every 10 minutes that captures and measures sentiment expressed by Twitter users about the presidential and vice presidential candidates. Here’s a screen-grab from a short while ago:

NetBase’s natural language processing engine analyzes each tweet about the candidates using its technology that understands how humans speak, including profanity and slang, according to the company’s news release. So the dials represent a moment in time, a cumulative group of tweet sentiment over the past 10 minutes – a real-time look into Tweeters’ opinions.

Here’s how it stacked up during last night’s debate:

Keep in mind that this only surveys those who are actively Tweeting – a younger-skewed demographic – and not the entire debate audience.
