How Do Professors Check For Plagiarism?

Today, with the fast development of the Internet and other technologies, such cases as low uniqueness occur more often than previously and due to this reason, all schools, colleges, and universities now use special plagiarism detection software and know how to check essay for plagiarism.

How Do Plagiarism Checkers Work?

In the past, it required lots of time and efforts to find all texts on the related subject and manually compare them with your own paper in order to detect similarities of sentences, ideas, and formulations. Today, it is much easier with the help of special checkers. Such programs' main purpose is to find a percentage of similarity between the given piece of writing and all existing sources that have the same subject. Thus, now it is not too difficult or time-consuming to find out whether a student had copy-pasted his text or wrote it from scratch.

How do checkers work? Although there are many different types of such programs, the algorithm of work and the final goal are the same regardless which software you are using. Such programs analyze various texts to search for exact or diluted similarities of word forms and phrases.

The first checker has been invented a long time ago. Along with years, it improved, became more sophisticated as a tool for finding non-unique pieces but the principle of work remains unchanged even today. The search is based on the semantic analysis of a text (it divides a piece into separate parts, splitting them into constituent segments) and then the tool looks for matches of each segment with other pieces available on the Internet. What happens next? When some matches were found, this program marks these passages, phrases or words with a certain colored, indicating the sources where these matches were found after a general analysis.

Now you know how do plagiarism checkers work? But how can you change the outcome of such check? In order to increase the uniqueness of your document, you have to paraphrase all highlighted phrases, put them in quotation marks if it is a quote or make a reference to the source’s author when the particular data was found.
