Abstract
Data-to-text generation, a subfield of natural language generation, increases the usability of structured data and knowledge bases. However, data-to-text generation datasets are not readily available in most domains and those that exist are arduously small. One solution is to include more data, though usually not a straightforward option. Alternatively, data augmentation consists of strategies which artificially enlarge the training data by incorporating slightly varied copies of the original data in order to diversify a dataset that is otherwise lacking. This work investigates augmentation as a remedy for training data-to-text generation models on small datasets. Natural language generation metrics are used to assess the quality of the generated text with and without augmentation. Experiments demonstrated that, with augmentation, models achieved equal performance despite the generated text exhibiting different properties. This suggests that data augmentation can be a useful step in training data-to-text generation models with limited data.
