What is Plagiarism in Research?

Plagiarism is presenting someone else’s ideas, words, or data as your own without proper acknowledgment. In academic research, it is considered a serious ethical violation.


Types of Plagiarism in a PhD Thesis:

  • Direct Plagiarism – Copying text word-for-word.

  • Self-Plagiarism – Reusing your own published content without citation.

  • Mosaic/Paraphrasing Plagiarism – Rewriting with slight changes but keeping the original meaning.

  • Accidental Plagiarism – Forgetting citations or using similar sentence structures unknowingly.


Why Universities Reject Plagiarized Thesis

Most global universities and UGC guidelines demand a plagiarism-free thesis. Even a small percentage of duplication can lead to:

  • Thesis rejection or revisions.

  • Journal article rejection during peer review.

  • Academic penalties, including suspension.

  • Loss of credibility and research reputation.

👉 Acceptable similarity index: Most institutions allow below 10–15% similarity, which is often referred to as the acceptable plagiarism percentage for PhD thesis, after excluding references and quotations.
