Table 10: Feature Group Performance on FCE-Test
['[BOLD] Feature Group', '[BOLD] Pearson Correlation', '[BOLD] MAE']
Like with the experiments using TOEFL11Subset, the next step with this corpus too is to study which features contribute to a good prediction. For each feature group, we built three models - one with all features from the group, one excluding prompt and one excluding native language. However, in all the cases, removing prompt and native language did not have a significant effect on the results. So, only the results with all features (= features of the group+prompt+nl) are reported in the table.
