Matthew Buckland, the general manager of Mail & Guardian Online, noted the move on his blog.
“It’s allowed us to group stories by country or city, as well as by people or company names, and serve related data — all automatically. We can also use the Calais data to generate tag clouds for each section of the site,” he wrote.
Open Calais allows online publishers to automatically identify and add tags for the people, places and organisations mentioned in their copy. A new version of the service, along with tools to integrate it into several content management systems, was recently released.
