Tattler (app) is an open source topic monitoring tool for today’s Web. Tattler finds and aggregates content from the Web on the topics you want. Using semantic Web technologies, Tattler mines news, websites, blogs, multimedia sites, and other social media like Twitter, to find mentions of the issues most relevant to a journalist, researcher, advocate or communications professional.

Built and distributed on open source Drupal, Tattler’s allows a user to easily filter, organize and share content gathered from the Web.

Managing News isn’t the only Drupal-based media- (and social-media-) monitoring tool out there. Tattler, from Phase2 Technologies, is also built on the open-source content management platform… and comes from a company that helped to build the new White House web site.

Then again, Managing News comes from Development Seed, which does a lot of work for United Nations agencies… so there’s kind of an embarrassment of riches when it comes to well-regarded, highly-qualified Drupal companies creating online media monitoring tools. I’ll look forward to checking Tattler out.
