+## Bias, Risks and Limitations
+
+Several limitations should be considered:
+
+- Language distribution is imbalanced, with English and major European languages being overrepresented.

+- The dataset mainly contains diagram-like images rather than natural scene text.
+
+- The dataset size is relatively small, which limits its use for large-scale training.
