-    "Augmenting data in character level. Possible scenarios include image to text and chatbot. During recognizing text from image, we need to optical character recognition (OCR) model to achieve it but OCR introduces some errors such as recognizing \"o\" and \"0\". `OCRAug` simulate these errors to perform the data augmentation. For chatbot, we still have typo even though most of application comes with word correction. Therefore, `KeyboardAug` is introduced to similar this kind of errors."
