Automatic spelling checking and correction process in a text processing system.

摘要

Process for improving the automatic spelling checking and correction in a text processing system by efficiently parsing a continuous string of intermixed text and control data into text words. The technique includes defining a set of word delimiters to parse the text stored in text buffer (2). A character segment is parsed from the text and transferred into a word buffer (4) where characters and control codes not affecting spelling are removed from the character segment by using a table memory (5). The character segment is then examined for alphabetic character content and verified if it contains no alphabetic characters. If the character string contains alphabetic characters, the beginning and ending punctuation are discarded and the string is scanned for internal punctuation. A comparison is made with the contents of a dictionary memory (6) at various points of the discard.
