The Accuracy of Grammarly Plagiarism Checker

1. Introduction

Due to the idea and search for the best free services for students, we have come across Grammarly, a service provided. Grammarly is an automated proofreader and your personal grammar coach. This product is worth for students to try out. It helps students identify potential grammar mistakes and also helps them choose better words to make their sentences more efficient. Most importantly, Grammarly is able to detect unoriginal text. Grammarly will provide a list of possible unoriginal text and list out the sources. All the student needs to do is reword the sentence or paragraph that has the potential of committing plagiarism.

Plagiarism is theft. According to the Oxford dictionary, plagiarism is taking someone else’s work or ideas and passing them off as one’s own. Plagiarism is taken seriously. It is a serious academic offense that is not tolerated. There are many ways people could commit plagiarism. One of the most common ways of committing plagiarism would be copying a text word by word. Other examples would be when an author “forgets” to use quotation marks to indicate a direct quote, or when people copy a program that someone else has written.

2. Methodology

The writer has used Grammarly plagiarism checker to find out the results for each translation. Unfortunately, it was not possible to record the results from Grammarly plagiarism checker. But the writer can assume the results since it was a “Unicode transformation” and he has been using Grammarly a lot in proofreading his own writings in English.

For this case, a proper sentence from English to Russian using a web-online grammar checker and revisions depending on the check are considered for data. This is done in order to find out the effectiveness of the grammar checker using the revisions.

Table 1. Sample UTF-8 data in Tamil shows the list of sentences and their translations using Google translator. The translations may or may not be accurate. The Google translator may change their translation at any time. Since this is the case, each sentence is translated more than once and the translations are recorded.

2.1 Data

This part of the study explains the methods that are used to apply the grammar checker. In this part, the writer only gives the data without comments.

3. Evaluation of Accuracy

It is stated by Atcagin and Senay that conventional spell checkers and grammar checkers from the older version of Microsoft Word work pretty well to determine an error in a simple text, and the error written is caused by mistyping. But when applied to a more complicated text, especially written by non-native speakers, the result is spotted to be less accurate. This can also be applied to the case of Grammarly. When students use Grammarly to check for errors in their assignments, most of the errors shown are suggestions to change the correct sentence into another correct sentence, or in other words, preferences. These preferences can vary depending on the style of the text. This is one thing that causes the inaccuracy of Grammarly. In order to compare the correctness of an error shown in Grammarly, we can use a native proofreader and see whether the proofreader will make the same correction as what is suggested by Grammarly.

The previous section emphasizes Grammarly as a comprehensive and powerful grammar checker, but having great power is not always a good thing. Accuracy is what is needed the most. In the case of Grammarly, the grammar checking result is not always accurate. From the entire essay, I conclude that this can be caused by either the limitation of corpus for non-native speakers and the complexity of grammar structure rules, which are unlimited and keep changing.

4. Comparison with Other Plagiarism Checkers

LEO DPC has a step-by-step guide for submitting a document, which is helpful for new users. The pricing is also similar to Plagscan at 5 cents per page. It is difficult to determine if LEO DPC would effectively detect unorthodox methods of plagiarism without using it and comparing results to other detectors.

Plagscan allows the user to determine the depth of the plagiarism scan, from simply browsing the web to comparing an uploaded document against the Plagscan database (which includes a large collection of books, journals, and articles). It costs 5 cents per page, with a page defined as 275 words. Compared to Grammarly’s detection method, it would likely have difficulty determining unorthodox methods of plagiarism. On the other hand, it may do very well at detecting unoriginal content that results from direct copying and pasting.

With Turnitin, its features include PeerMark, GradeMark, and WriteCycle. PeerMark allows educators to create and deliver peer review assignments, while GradeMark allows paperless grading that takes place directly within Microsoft Word. WriteCycle is a set of online writing tools that aid in the writing process. In order to receive pricing for Turnitin, one must contact a sales representative. Without this pricing information, it is impossible to compare the cost of Turnitin with other plagiarism checkers. Turnitin is said to be effective in detecting all forms of unoriginal content, which would include unoriginal content that results from translation.

After reviewing how well Grammarly’s Plagiarism Checker detected unorthodox methods of plagiarism, it’s time to compare it to other plagiarism detectors available on the internet. Some of the popular ones are Turnitin, Plagscan, Dustball, and EVE2. Comparisons include the features of each plagiarism detector, the cost to use each one, and how accurate each plagiarism detector is at detecting unorthodox methods of plagiarism.

5. Conclusion

As time and again the priority of content flagged as being plagiarized by Grammarly is not actual plagiarism, but content that is of a similar nature to an unknown source, this essay stresses the importance of the need for context for the plagiarism checking process.

However, it is also clear that often times finding passages that are flagged as being plagiarized is not an issue of grammar, but an issue of the quality of the source. In the case of using contemporary video game scripts as a source, some pieces of conversation have been flagged as being plagiarized due to them being identical to other sources on the internet. However, it has been verified that this is simply a case of coincidence, and that the source of the script has been plagiarized from the original author of the script at a later date.

With the issues of false positives and the relative ignoring of certain passages by the plagiarism checker brought into the light by this essay, it is hard to rely on Grammarly for a sure-fire way to ensure that a piece of writing is free from plagiarism. While the official statement from Grammarly is that “Plagiarism in any form is unacceptable and can have severe consequences for professional and personal lives. We will not tolerate plagiarism or the misuse of unrelated content,” its current form as a plagiarism checking tool still falls short of the high standard that it sets for itself when comparing plagiarism in the form of uncited duplication of content, to failing to cite a source correctly, and to content falsely deemed as plagiarized.

The Grammarly plagiarism checker is a highly praised tool in terms of finding faults and citation issues in your writing. However, as shown in this essay, its use as a tool to check for plagiarism does not lead to making an undeniably accurate decision when it flags a certain passage as being plagiarized, or not plagiarized, as is often the case.
