Title: A BERT Baseline for the Natural Questions,
Abstract: This technical note describes a new baseline for the Natural Questions. Our
model is based on BERT and reduces the gap between the model F1 scores reported
in the original dataset paper and the human upper bound by 30% and 50% relative
for the long and short answer tasks respectively. This baseline has been
submitted to the official NQ leaderboard at
ai.google.com/research/NaturalQuestions and we plan to opensource the code for
it in the near future.
