epulze-logoA company called ePulze has created a search engine that monitors public opinion and sentiment as expressed in the news and elsewhere online. The company has developed this technology specifically for advertisers, so that brands can change advertising campaigns as needed if public perception shifts.

EPulze is launching today at DEMOfall 09, the technology conference co-produced by VentureBeat. Judging from the presentation on-stage, it’s easy to use — you can enter one brand, or two if you want to compare them, and it will bring up a chart showing you sentiment has changed over time. You can also see how those mentions break down by source, and even jump to the specific website mentions.
