Calais (Reuters product)
Calais is a service by Thomson Reuters that automatically extracts semantic information from web pages in a format that can be used on the semantic web.[1] Calais was launched in January 2008, and is free to use.[2][3]
The Calais Web service reads unstructured text and returns Resource Description Framework formatted results identifying entities, facts and events within the text.[4] The service appears to be based on technology acquired when Reuters purchased ClearForest in 2007.[5]
The technology has also been used to automatically tag blog articles[6] and organize museum collections.[7]
Calais uses natural language processing technologies delivered via a web service interface.
