Plagiarism Policy

Last Updated: January 2026

Zero Tolerance Policy
The DELSU Journal of Computing & Information System (DJCIS) does not in whatever forms condone plagiarism or related issues. The Editorial Board will immediately take appropriate measures to sanction author(s) involved in plagiarism.

Definition of Plagiarism

Plagiarism is the wrongful appropriation and stealing of another author's work: language, opinions, concepts, or terminologies and representing them as one's own original work. DJCIS maintains a strict zero-tolerance policy against all forms of plagiarism.

Classes of Plagiarism

The following types of plagiarism are considered by DJCIS:

Self-Plagiarism

When an author reuses whole or portions of their pre-published research, it is identified as self-plagiarism. Complete self-plagiarism occurs when an author republishes their own formerly published work in a new journal.

Partial Plagiarism

If content is a combination from several different sources, where the author has widely rearticulated text, it is identified as partial plagiarism.

Full Plagiarism

Formerly published content without any changes to the text, idea, and grammar is considered full plagiarism. It encompasses presenting a text from a source as one's own work.

Plagiarism Detection

Plagiarism Check: All manuscripts submitted for publication are cross-checked for plagiarism using professional plagiarism detection software before the review process.

18% Maximum Allowed Similarity
(excluding references and author info)

Important Notice
Excluding author information and bibliography, the maximum plagiarism allowed is 18% at a string of three (3) consecutive words. Any manuscript exceeding this threshold will be immediately rejected or returned for revision.

Consequences of Plagiarism Before Publishing

DJCIS frowns seriously on plagiarism by authors and will pass judgment on any instance of plagiarism within its jurisdiction. If plagiarism is noticed by the Editorial Board Committee, Review Committee, or any other body in any phase of the article process—before or after acknowledgment, during review, or at proof stage—the following actions will be taken:

  • The author(s) will be immediately notified of the detected plagiarism
  • The author(s) will be requested to revise the content or properly cite the references from which the content has been taken
  • In severe cases, the manuscript will be rejected outright
  • Repeat offenders may be banned from submitting to DJCIS for a specified period

Consequences of Plagiarism After Publication

If plagiarism is discovered after publication, DJCIS will:

  • Issue a formal retraction of the article
  • Notify the author's institution and funding bodies
  • Ban the author from future submissions to DJCIS
  • Publish a retraction notice in the next available issue
Note for Authors
DJCIS does not permit any type of plagiarism or pre-published submissions. Authors are encouraged to subject their manuscripts to plagiarism checks via web-based/online plagiarism checking software before submission.

Best Practices for Authors
To avoid plagiarism, authors should: properly cite all sources, use quotation marks for direct quotes, paraphrase appropriately with attribution, and always provide references for ideas and data that are not their own. When in doubt, cite the source.
