Abstract:
A method of diacritical processing for unconstrained, on-line handwriting recognition using a forward search comprising:scanning an ink stream of handwritten input to identify potential diacriticals; building a list of diacriticals; traversing the ink stream; processing a potential diacritical-containing character; scoring the potential diacritical-containing character without adding a diacritical to generate a first score for a first variant of the potential diacritical-containing character; scoring the potential diacritical-containing character with a diacritical selected from the list of diacriticals to generate a second score for a second variant of the potential diacritical-containing character; comparing the first score with the second score in order to make a decision as to which variant of the potential diacritical-containing character produced a highest score; using the highest score as a score for a theory, wherein the theory consists of a current character hypothesis and a record of a character string preceding the current character hypothesis; and recording the decision.
