Abstract
In a computing device that receives handwritten data, a method and system that corrects for parser segmentation errors by sending an entire line of ink to a recognizer, and then comparing, on a word-by-word basis, the initial segmentation guesses of the parser with the more-thoroughly recognized segmentation results of the handwriting recognition engine. In the correction process, the ink words are efficiently adjusted with relatively little data manipulation. As the recognizer is fed a series of strokes on a line, the recognizer returns segmentation information. For ink word breaks that are the same for any given set of data, the existing ink word is unchanged. For ink words that are recognized differently relative to their initial segmentation, one or more new ink words are created and the handwriting (including stroke) data of the parser's ink word is manipulated to create a new ink processor word (or words) to match the recognizer output.
