Calais: Connect. Everything.

We want to make all the world's content more accessible, interoperable and valuable. Some call it Web 2.0, Web 3.0, the Semantic Web or the Giant Global Graph - we call our piece of it Calais.

What Calais does sounds simple – what you do with it could be simply amazing. 

The Core: The Calais Web Service

The Calais Web Service automatically creates rich semantic metadata for the content you submit – in well under a second. Using natural language processing, machine learning and other methods, Calais analyzes your document and finds the entities within it. But, Calais goes well beyond classic entity identification and returns the facts and events hidden within your text as well.

This metadata gives you the ability to build maps (or graphs or networks) linking documents to people to companies to places to products to events to geographies to… whatever. You can use those maps to improve site navigation, provide contextual syndication, tag and organize your content, create structured folksonomies, filter and de-duplicate news feeds, or analyze content to see if it contains what you care about. 

The Tools: A Growing Ecosystem of Calais-Enabled Capabilities

The Calais Web Service is a powerful capability - but using it to deliver value to real people requires applications and the tools to build them. Major focus areas of the Calais initiative are delivering the tools with which to build great applications and fostering the community of developers that will make those applications happen.

The "Open" in Calais

The web service is free for commercial and non-commercial use. We’ve sized the initial release to handle millions of requests per day and will scale it as necessary to support our users.
