How Does the Graid Essay Marking System Work?

Last Published: 27/02/22
One of the greatest benefits of the GRAID platform is the ability to get instant feedback on your writing. But where does the feedback come from? How does GRAID's system know how to grade and essay? The answer lies in GRAID's cutting edge technology that utilises an area of artificial intelligence called "natural language processing" to evaluate your work. Natural language processing is a field of technological innovation that looks at the relationship between computer science and human language. One of its major techniques is to develop algorithms that evaluate how language is used according to certain rules, structures, goals and objectives.

How is this relevant to your IELTS study? Well, the most important aspect of GRAID's algorithm is that it has been "trained" by examining in close detail thousands of IELTS essays that have been scored by regular human markers. By analysing these essays according to hundreds of parameters, the system has learnt what characterises a successful essay and what characterises a less successful essay. It has been able to capture the intelligence contained in this data and apply it to your practice essay. It looks for all the key parameters of an IELTS essay (including things like word count, paragraph structure, and the right sentence types) and assesses how well you have completed the task. It then give you pointers on what you can do better next time. So when your hard work pays off and you achieve that top score on your practice essay, you'll know that it reflects the fact that your work is up there with the best.
