Abstract
A method and apparatus for training a recognizer includes displaying a practice word on a display screen of a pen-based computer system and entering a handwritten word that is similar to the practice word on the display screen. A recognized candidate list that includes candidate words and an associated confidence level for each candidate word is derived from the handwritten word by a recognizer. The confidence level indicates how confidently the handwritten word has been matched to the associated candidate word. The candidate list is displayed and a training database is updated with training data derived from the handwritten word. The training data is used by the recognizer to recognize other handwritten words with greater accuracy. A practice word that is either easily recognized by the recognizer or recognized with difficulty can be displayed, and the easily recognized practice words are randomly retrieved from a dictionary tree of characters to provide words of reasonable length and a variety of types and combinations of characters.
