Advanced scoring

Instead of pointing just a similarity score, we offer you many more scores to evaluate the paper.

Plagiarism checker advanced scoring

All reports are provided with a similarity score. This score shows how many similarities are in your documents.

The similarity score is counted by diving the number of matched words by the number of total words.

For example, if your document contains 1000 words and the similarity score is 21%, this means that there are 210 matched words in your documents.

Plagiarism similarity score

This score shows you the risk of plagiarism in your document. This score, in general, evaluates the size of similarities. The bigger the block of similarity is, the bigger is the risk of plagiarism.

For instance, let’s take a 100-page paper with only 1% of similarity. If all the similarities will be concentrated on one page only, our plagiarism risk score will show the highest value. You will be alerted on possible plagiarism instances with low similarity value.

Our research has shown that this feature detects plagiarism with an accuracy of 94%.

Paraphrasing is the increasing method of plagiarizing. To deal with paraphrasing, we added a paraphrasing score.

This score shows what part of the text is rewritten.

The paraphrase score usually is between 1% and 8%. A high paraphrase score may signal plagiarism. Be aware of the high paraphrasing score.

Citing is what consists of a good paper. However, some good citations might just be a part of the bigger block of similarity.

For such cases, we have introduced the concept of improper citations.

The improper citations show how many citations are just parts of bigger similarities there are in the document.

Improper quotation

Citations are part of every paper. Citing other documents adds credibility to the paper.

We identify citations and mark them with green color. This lets you easily distinguish good citations from other similarities.


The credibility of the paper may be also assessed by the number of matches.

Imagine that you are dealing with the paper with 10% of the similarities. Which one will look more credible to you – the one in which all the 10% were taken from only one source or the one in which similarities come from tens or hundreds of sources?
