FAQ
How is sentence similarity measured?
Using Jaccard similarity — the proportion of shared words between two sentences' word sets — which is fast to compute and works well for catching near-identical phrasing.
What counts as a 'near duplicate'?
Sentences at or above roughly 80% word overlap are flagged as near-duplicates; exact repeats are flagged separately at 100%.
