สรุป	Idea plagiarism, or conceptual plagiarism, occurs when an author takes another's ideas, arguments, theories, or conceptual frameworks and presents them as original work without crediting the source. Unlike verbatim or paraphrasing plagiarism (which involve copying language), idea plagiarism involves taking the intellectual content itself—the argument, theory, or framework—regardless of how it is worded. It is the hardest form of plagiarism to detect because it does not require word-for-word copying.	Paraphrasing plagiarism occurs when an author rewrites another's ideas in different words but does not cite the source. Unlike verbatim plagiarism (copying word-for-word), paraphrasing plagiarism involves changing vocabulary and sentence structure while retaining the original argument, logic, or conceptual content without attribution. It is harder to detect than direct copying but is still a clear violation of academic integrity.	A critical distinction exists between similarity percentages generated by plagiarism detection software (Turnitin, iThenticate) and an actual plagiarism verdict. A similarity index is a red flag requiring review; it is not a plagiarism determination. High similarity can result from legitimate quotations, references, shared technical language, or common knowledge. Conversely, low similarity does not guarantee absence of plagiarism. Human expert judgment is essential—similarity detection software provides data, not judgment.
