Abstract
A method and system of recognizing words from handwritten symbols that are recognized by a computer recognizer. The recognizer produces a set of one or more alternatives for each symbol and orders the alternatives within each set in terms of the probability that each alternative matches the handwritten symbol for the set. A sequence of strings, each string having one alternative from each set, is enumerated. The enumerating proceeds in order such that the most probable alternatives from each set are used before the lower probability alternatives. Preferably, each string enumerated is looked up in a computer dictionary before enumerating other strings. If the string is found in the dictionary, the string is displayed, and preferably further enumerating stops. In an alternative embodiment, plural strings are enumerated before looking up a string in the dictionary. In another embodiment, plural strings are displayed before stopping further enumeration. Amended symbols may be used to change individual characters within a previously recognized word. A set of alternatives for each amended symbol is coupled with the unchanged symbols before enumerating strings and looking the strings up i…
