It is APU's plagiarism detection service that identifies potentially plagiarized or improperly cited text. APU has integrated the software within our Canvas instance. The service automatically checks submitted work against an ever-increasing index of online sources.
Our AI-powered plagiarism scans offer 3 layers of text similarity detection (identical, minor changes, & paraphrased) in order to give you the most accurate results. Based on your scan settings, we also provide information on how much of the text you are not scanning for plagiarism (omitted words).
Identical- 1 to 1 exact word matches, highlighted in red.
Minor changes- text that has some minor variations from the source but conveys the same meaning. Example: changing "he was running" to "he ran". Highlighted in light red.
Paraphrased- text that is rewritten using different words or sentence structures, but the core idea remains the same.
Omitted- the portion of text that is not being scanned for plagiarism based on the scan settings. (example: the ignore quotations setting is enabled and the document is 20% quotations = the omitted words percentage is 20%), unhighlighted.
