Originality, similarity and risk: how to read a plagiarism report
Understand the difference between originality, similarity and risk in a plagiarism report and what each indicator means before you submit your work.
You ran the check and got three numbers: originality, similarity and risk. What does each one mean? Understanding this avoids needless panic — and also false confidence.
Originality isn't everything
Originality is the headline score: how much of the text doesn't match other sources. But a high score alone doesn't guarantee you're safe. That's why good reports include two more indicators.
The three indicators
- Originality: the percentage of text that looks like yours. Higher is better.
- Similarity: when there's a match, how close it is. An identical sentence weighs more than a similar one.
- Risk: a combined read — it blends how much is matched, how intense the matches are and the type (literal copying weighs more than paraphrase) to indicate the real chance of trouble.
Two papers can have the same originality and very different risk: one with several identical uncited sentences is worse than one with short, common matches.
What to do with the report
- Go to the flagged passages, not just the number.
- For each, decide: missing citation? paraphrase to rewrite? common phrase (false positive)?
- Prioritize the high-risk ones (literal copying with no source).
- Fix and re-run.
