Gramatika

Gramatika is a syntectic GEC dataset for Indonesian. The Gramatika dataset has a total of 1.5 million sentences with 4,666,185 errors. Of all sentences, only 30,000 (2%) are correct sentences with no mistakes. Each sentence has a maximum of 6 errors, and there can only be 2 of the same error type in each sentence.We also split the dataset into three splits: train, dev, and test splits, with the proportion of 8:1:1 (with the size of 1,199,705, 150,171, and 150,124 sentences, respectively). The proportion of valid sentences in each split is 2%; 24,000 in the train split, and 3000 in each dev and test split. Moreover, we also set the proportion of each error type in all splits to be the same, as shown in Table 3.3.2. For example, the proportion of noun errors is 7.5% in all splits, while the proportion of particle errors is also only 0.3% in all splits.
