Plagiarism Policy

Corporum: Journal of Corpus Linguistics adheres strictly to the plagiarism standards mandated by the Higher Education Commission (HEC) of Pakistan. These standards govern every stage of the submission and review process, ensuring that the scholarly record remains authentic and ethically sound.
The official HEC plagiarism policy is accessible at:

https://hec.gov.pk/english/services/faculty/Plagiarism/Pages/default.aspx

All manuscripts submitted to Corporum undergo plagiarism screening through Turnitin, and the similarity thresholds are enforced rigorously. The acceptable limits for similarity are:

• Less than 19% total similarity, and
• No more than 5% from any single source, excluding references and standard methodological text.

Manuscripts that exceed these limits are returned to authors for revision or may be rejected in cases of severe or unrectifiable similarity. Corporum defines plagiarism broadly and includes within it: verbatim copying, improper paraphrasing, failure to acknowledge sources, reuse of previously published material (self-plagiarism), and unattributed reproduction of text, figures, ideas, or data. Any violation is considered academic misconduct.

To operationalize and enforce this policy, Corporum requires every author to complete and sign the officially issued “Plagiarism & AI Acknowledgement Form” before submission.

Plagiarism & AI Acknowledgement Form: https://drive.google.com/file/d/1Y8Go3ACx7VXn7Pqv-ZEtNyGL4QBIlYZt/view?usp=sharing

This form serves as an integral ethical safeguard and must accompany each manuscript. In signing the form, authors certify that:

1. The manuscript is entirely original and has not been published or submitted elsewhere.
2. All sources have been properly cited, including any prior work of the authors.
3. The manuscript meets the HEC-mandated similarity thresholds.
4. AI tools have been used only within ethical and approved limits.
5. Any AI-assisted contribution has been transparently disclosed in the manuscript.

A manuscript will not enter the review process unless the completed form bearing the names, signatures, affiliations, ORCID IDs, and declarations of all authors is submitted along with the article. Corporum reserves the right to verify the authenticity of the declaration at any stage of the editorial process. In cases of proven misconduct, unethical use of AI, or falsified similarity claims, the journal may take corrective action, which may include rejecting the manuscript, notifying the authors' institution, or taking additional measures in accordance with the HEC policy.

This integrated approach, consisting of Turnitin screening and a mandatory signed declaration, ensures full compliance with national academic standards and upholds the journal’s commitment to maintaining the scholarly integrity of its published content.
