Find Out How Plagiarism Checkers Work

Today information becomes more and more essential resource: that’s why most people think of the quality of this resource. How to do it? How the term "plagiarism" can be referred to the quality of the content and what are the tools to assess the copyrighted material?
From a legal point of view, plagiarism is a deliberate attribution of authorship of another's artwork, invention or technological solutions. However you shouldn’t refer quotation, imitation or borrowing of ideas to plagiarism if the copy does not contain elements of the specific technical writing - the idea itself may not be subject of copyright.

How Plagiarism Detection Works


The problem of information uniqueness has become even worse because of the development of Internet: the number of web sites has increased exponentially, and the technical solutions for determination of authorship do not exist. However there is a nice way out of the following difficulty - online services and various programs. They allow the users to analyze the text and identify the non-unique fragments in it.

But don’t jump to conclusions and learn how plagiarism software works. In fact it does not act like dishwashers with dirty plates or car starters with cars. It means the checkers can’t detect plagiarism. Instead of it they just check some episodes, paragraphs and small sections. The programs look for matching strings of the words in the document and compare them to the ones in its index. You’ll see it while working with WCopyFind, Copyscape, Turnitin etc.

The Limitation of Every Plagiarism Checker

So plagiarism detection software can only find the cases of copying or detect similar phrases. However there are some situations when the checkers have no chances for winning the authors. 
First of all non-verbatim plagiarism should be mentioned. It means the program won’t be able to find plagiarism if translating, rewriting or other similar methods are used. In other words it can’t see whether the writer has taken the idea but just check the available words in the text.
One more weakness of such checkers is common phrasing. In this case authors try to separate words with attributes and add to the text common phrases. 

Misunderstandings about Plagiarism Software

It’s very important to learn misunderstandings about plagiarism checking software as they like any other tools should be used properly in order to remain effective. Here are some of them:
Plagiarism detectors are used only by plagiarists. Despite the ability to find and stop plagiarists, the checkers can be a nice tool in improving writing skills: missing citations, poor paraphrasing or even grammar. 
Plagiarism software is easy to deceive. Some users are sure they are smart enough to fool plagiarism detectors. They try to omit some word or even a passage. In fact, they are to change almost every third word so it’s more difficult than rewriting the whole document.
Plagiarism detectors are not very accurate. They say plagiarism services miss all matched content and even can produce some false positives. In another words they are inaccurate. But in fact, it’s not always true.
Detectors identify plagiarism automatically. Mind a highlighted passage represents a possible case of plagiarism. In fact, only user can make the final judgment if it’s true or not. 
All plagiarism checkers are the same. The truth is free plagiarism detectors are not ideal at all if speaking about professional use. It’s because they have small databases, and even can be less accurate than professional plagiarism checkers. That’s why the last ones have gained the great reputation in high quality content.


Finally, like other similar tools plagiarism detectors are just machines so they also can and do some mistakes. So they are almost useless without intelligent humans. Software that can detect plagiarism needs a nice partner to improve the general result in the end.
