... correct parts in it. In this paper we therefore propose a method for correcting errors, which is characterized by learning the trend of errors and expressions, and by processing in an arbitrary ... the string including errors from the String- Database (the former string is referred to as the Similar-String, and the latter as the Error-String). Finally, the correction is mad...
