- Abstract: Simple yet effective data augmentation techniques have been proposed for
sentence-level and sentence-pair natural language processing tasks. Inspired by
these efforts, we design and compare data augmentation for named entity
recognition, which is usually modeled as a token-level sequence labeling
problem. Through experiments on two data sets from the biomedical and materials
science domains (i2b2-2010 and MaSciP), we show that simple augmentation can
boost performance for both recurrent and transformer-based models, especially
for small training sets.

Another popular technique is to create synthetic data from the original labeled data.
In this work, we investigate the impact of these two methods on the performance of three different named entity recognition tasks.
