Plagiarism Detection Software

Plagiarism is the representation of another author's language, thoughts, ideas, or expressions as one's own original work.
Plagiarism is a common (and often misunderstood) problem that is often the result of a lack of knowledge and skills. Our mission is to support the education community with a comprehensive set of resources to help students write with integrity.
According to the Merriam-Webster online dictionary, to "plagiarize" means:

• to steal and pass off (the ideas or words of another) as one's own
• to use (another's production) without crediting the source
• to commit literary theft
• to present as new and original an idea or product derived from an existing source

In other words, plagiarism is an act of fraud. It involves both stealing someone else's work and lying about it afterward.

Different classifications of academic plagiarism forms have been proposed. Many classifications follow a behavioral approach, i.e., they seek to classify the actions undertaken by plagiarists.
Turnitin identified 10 main forms of plagiarism that students commit:

• Submitting someone's work as their own.
• Taking passages from their own previous work without adding citations (self-plagiarism).
• Re-writing someone's work without properly citing sources.
• Using quotations but not citing the source.
• Interweaving various sources together in the work without citing.
• Citing some, but not all, passages that should be cited.
• Melding together cited and uncited sections of the piece.
• Providing proper citations, but failing to change the structure and wording of the borrowed ideas enough (close paraphrasing).
• Inaccurately citing a source.
• Relying too heavily on other people's work, failing to bring original thought into the text.
