The Callisto annotation tool was developed to support linguistic annotation of textual sources for any Unicode-supported language. Information Extraction (IE) systems are increasingly easy to adapt to varying domains, and by using machine learning techniques, this process is becoming largely automatic. However, adaptive/adaptable systems require training and test data against which to measure and improve their performance. Hand annotation can be an arduous task, but a well designed user interface can greatly ease the burden. This is the function of Callisto.
