Error Detection and Correction of the Modified International Standard Serial Number

Abstract

The International Standard Serial Number (ISSN) code is internationally used for identifying the title of serial publications. This research aims at determining the error detection and correction capabilities of the International Standard Serial Number code against the dictionary size. ISSN code has a relatively small dictionary size and is not effective in error detection and correction capabilities. The study develops a modified International Serial Number code and determines its error detection and correction capabilities against its dictionary size. The study utilizes weight checksum technique to detect and correct error(s). Moreover, the study designs an algorithm for conversion of ISSN code words to the modified ISSN code words. The total number of code words is established by how many digits permute. Modified ISSN code is effective in error detection and correction capabilities for it has dual mechanism for detection and correction of errors, if the weight checksum equation does not hold and if the conditions for the generating equation does not hold.
