Verbatim Plagiarism
Definition
Copying text word-for-word from a source without attribution. The simplest form to detect computationally because character-level matching directly finds the copied string.
- Detection method
- Character or string-level matching, e.g. n-gram or suffix-tree comparison
- Difficulty
- Easiest plagiarism type to detect computationally
- Contrast
- Paraphrase and translated plagiarism, which need semantic comparison
- Typical output
- A percentage or highlighted-passage similarity report
Common questions
Why is verbatim plagiarism the easiest form to catch?+
Because the copied text is identical or near-identical to the source, exact string matching against a reference corpus finds it directly without needing to understand meaning.
What forms of plagiarism does string matching miss?+
Paraphrased text, translated passages, and idea theft without copied wording all evade character-level matching and require semantic or stylometric analysis instead.
