Tagaroo is a visually appealing and searchable tagging tool for bloggers powered by Calais. Calais is an initiative by Thomson Reuters to connect the world’s content by providing automated metadata (let’s just call it tagging) services. The Calais service takes your text and uses sophisticated natural language processing and machine learning algorithms to extract the people, organizations, companies, geographies and events hidden within it. In all Calais is pretty smart at recognizing a couple of hundred different things – and growing in capabilities every month.
