The Journal of Computer and Engineering Sciense is responsible for maintaining the integrity and completeness of our scientific records of content for all readers very seriously. This journal places great importance on the authority of articles once published and our policies are based on best practices in the academic publishing community. Changes to articles once published online can only be made in the circumstances outlined below.
Errata is the author's statement of the original paper which briefly describes any corrections resulting from errors or omissions. Any effect on the paper's conclusions must be considered. The corrected article was not removed from the online journal, but notice of the error was provided. Errors are freely available to all readers and are linked to the corrected article.
Revocation is a notification that a paper should not be considered part of the scientific literature. Revocation is issued when there is clear evidence that the findings are unreliable, this could be due to misbehavior or dishonesty; if the previous findings have been published elsewhere without proper reference, permission or justification; if the work is plagiarized; or if anyone reports that the research is unethical. To protect the integrity of the records, revoked articles are not removed from the online journal, but a takedown notice is provided, available free to all readers, and linked to the recalled article.
Publisher Notes notify readers that the article was corrected after it was published. It is issued by the Publisher and is used in cases where a typo or production error (which is a Publisher's error) affects the integrity of the article metadata (such as title, author list or byline) or would significantly affect the reader's ability to understand the article. The original article was removed and replaced with a corrected version. Publisher's Notes are available free of charge to all readers. Minor errors which do not affect the integrity of metadata or the reader's ability to understand an article and which do not involve scientific errors or omissions will be corrected at the discretion of the Publisher.
In such cases, the original article is deleted and replaced with an improved version. The date the correction was made is recorded in the corrected article. Authors should also be aware that the original article can only be removed and replaced with a corrected version less than one year after the original publication date. Corrections to articles that have a publication date that are longer than one year will only be documented by Publisher Records.
