Abstrakt

Data augmentation techniques have been widely used in visual recognition tasks as it is easy to generate newdata by simple and straight forward image transformations. However, when it comes to text data augmen-tations, it is difficult to find appropriate transformation techniques which also preserve the contextual andgrammatical structure of language texts. In this paper, we explore various text data augmentation techniquesin text space and word embedding space. We study the effect of various augmented datasets on the efficiencyof different deep learning models for relation classification in text.
