+ We trained a language model to **automatically score the IELTS essays** by using massive the training dataset by human raters.
8
+
9
+ The impressive result in the test dataset is as follows: **Accuracy = 0.82, F1 Score = 0.81**.
10
+
11
+ The following is the code to implement the model for scoring new IELTS essays.
12
+
13
+ In the following example, an essay is taken from the test dataset with the overall score 8.

15
+ ```
16
+ # Import necessary packages
17
+ from transformers import AutoModelForSequenceClassification, AutoTokenizer
18
+ import torch
19

21

22

24
+ tokenizer = AutoTokenizer.from_pretrained("distilbert-base-uncased", use_fast=True)

29

30
+ "Do you agree or disagree with this statement? It is crucial for all metropolitan cities and towns to "
31
+ "have some recreational facilities like parks and squares because of their numerous benefits. A number of "
32
+ "arguments surround my opinion, and I will discuss it in upcoming paragraphs. To commence with, the first "
33
+ "and the foremost merit is that it is beneficial for the health of people because in morning time they can "
34
+ "go for walking as well as in the evenings, also older people can spend their free time with their loved ones, "
35
+ "and they can discuss about their daily happenings. In addition, young people do lot of exercise in parks and "
36
+ "gardens to keep their health fit and healthy, otherwise if there is no park they glue with electronic gadgets "
37
+ "like mobile phones and computers and many more. Furthermore, little children get best place to play, they play "
38
+ "with their friends in parks if any garden or square is not available for kids then they use roads and streets "
39
+ "for playing it can lead to serious incidents. Moreover, parks have some educational value too, in schools, "
40
+ "students learn about environment protection in their studies and teachers can take their pupils to parks because "
41
+ "students can see those pictures so lively which they see in their school books and they know about importance "
42
+ "and protection of trees and flowers. In recapitulate, parks holds immense importance regarding education, health "
43
+ "for people of every society, so government should build parks in every city and town."
