We doubt you would buy a cup without a bottom, no matter how nice and cheap it is. The same applies to plagiarism-checking software – you must ensure the tool performs its main function efficiently. That is why plagiarism checker accuracy is the defining factor in choosing reliable plagiarism software.

What defines plagiarism detection accuracy?

The efficiency of the originality-checking software depends on the text type, the language, and the tool’s database – the more sources a similarity checker analyzes, the more precise results you get.

Moreover, each tool has algorithms enabling it to dig deep into details. For example, PlagiarismCheck.org highlights not only exact matches with content found in the vast database. It indicates the words substituted with synonyms, changing sentence voice from passive to active and vice versa, as well as word order and structure rearrangement.

How to ensure plagiarism checker accuracy

When you scan for plagiarism, it is crucial to recognize that none of the analyzing software is a miracle pill providing 100% accuracy. A trustworthy tool is paramount, but it is up to you to make the final decision.

No benchmark regarding the acceptable percentage of alleged plagiarism exists. Less than 20% are roughly regarded as allowed – however, if the match applies to a particular part of the text only, it may indicate it has been copied.

At the same time, more than 70-80% similarity seems to be a sign you should not waste your time checking the paper. However, that can be a case of unintended plagiarism: follow the links to check the original resources and talk to a student to clarify the situation.

European Network for Academic Integrity’s study proves PlagiarismCheck.org to be one of the top three content similarity detection systems in terms of efficiency. Join us to try our AI Checker and check plagiarism for free now!
