+Chemical specific parameters are either measured _in vitro_ or estimated using quantitative 
 structure–activity relationship (QSAR) models. The existing body of QSAR work relies on extracting a 
 set of descriptors or fingerprints, subset selection, and training a machine learning model. In this work, 
 we used a state-of-the-art natural language processing model, Bidirectional Encoder Representations from Transformers
