In the report, you will see some colors above your sentences in your document. Well, three colors to be exact – red, blue, and green.

Red is for ‘Exact Match’, which means the sentence is more than 90% similar to another in our database.

Blue is for “probably altered text” which means that the sentence has been altered in some way by another, perhaps paraphrased incorrectly.

Green is for ‘Citations’ which means the sentence is quoted from another source.

The Report section

On clicking on “Report” on the dashboard, we will notice a navigation bar above the document that sends us through the pages where there are similarities. 

When we navigate through these pages we see the shaded parts and when we click on them, the information summary appears. Sentence information shows where your sentence came from a source the words taken are shaded in red and the source appears above. 

In addition to the navigation bar, we have another table on the right side that shows the resources your document may resemble.

Sources are documents such as theses, articles, reports, or works based on research, and in cases where similarities are discovered in our articles, then sources are displayed by the plagiarism checkers.

Types of resources

The types of resources that appear in Crossplag are:

All sources are the sources that your work results in similar to.

The top three sources are the sources where your work has resulted in a higher percentage of similarity and it is always good to go to them to make changes to our document so that we are not verified for similarity in our document.

Internet sources are those sources that our work has resulted in similar to online sources on the Internet and appear in this list.

And internal sources, which are documents archived in Crossplag, and your document may also be similar to them.

We can change the source in Crossplag to a specific sentence that may have three or four sources and make another source that has less similarity to the main source.

There are also excluded sources. We can understand the excluded sources through a simple example.

For example, when a sentence is a general knowledge like ‘Facebook is a social network which was created in 2004 by Mark Zuckerberg’ and is considered plagiarism because, well someone obviously mentioned it before us for it’s a fact, we can exclude the source. 

Such sentences that are general knowledge each plagiarism detector can specify as similar to some other online articles. 

But even if you exclude it, it will be shaded with a gray color, which is known as a ‘removed highlight’, which still shows that there are similarities in the text, but the author has removed them.
