1. A spelling correction method for an electronic device comprising:
- (a) selecting context-sensitive strings, which have different meanings according to context, from among all strings registered in a misspelling correction dictionary stored in a memory on a basis of a corpus of accepted words;
(b) acquiring context information about the context-sensitive strings;
(c) receiving a user'"'"'s input sentence by the electronic device;
(d) selecting at least one target string from among all strings in the user'"'"'s input sentence through the misspelling correction dictionary; and
(e) correcting, when the target string is one of the context-sensitive strings, the target string by using the context information;

Abstract
A spelling correction system and method automatically recognizes and corrects misspelled inputs in an electronic device with relatively lower computing power. In a learning process, a misspelling correction dictionary is constructed on the basis of a corpus of accepted words, and context-sensitive strings are selected from among all the strings registered in the dictionary. Context information about the context-sensitive strings is acquired. In an applying process, at least one target string is selected from among all the strings in a user'"'"'s input sentence through the dictionary. If the target string is one of the context-sensitive strings, the target string is corrected by use of the context information.
