A Post-Processing Error-Correction Scheme Using A Dictionary For On-Line Boxed And Run-On Handwriting Recognition

Abstract

Because of similar shape letters such as "v" and "u"; "k" and "h"; "1", "l", and "I"; and so on, plus many noisy channels such as digitizer tablets that intended hand-inputs should go through, any on-line recognition of handwriting letters cannot avoid producing errors. The use of a large vocabulary dictionary is necessary to make the system practically usable. However, imposing a limitation on the vocabulary handled by a recognition system is not very desirable for practical purposes. This paper presents a novel structure of a dictionarydriven error-correction post-processor for an online handwriting recognition environment which does not impose any coarse restriction on the vocabulary, however, it makes use of a large dictionary to reduce the errors made by the recognizer. This error- correction scheme reduces the error of a run-on and boxed handwriting recognizer by more than one half. 1 Introduction The notion of using a handwriting interface to computers has been of great interes..
