Using Prior Knowledge to Guide BERT's Attention in Semantic Textual Matching Tasks

1 code implementation • 22 Feb 2021 • Tingyu Xia, Yue Wang, Yuan Tian, Yi Chang

We study the problem of incorporating prior knowledge into a deep Transformer-based model, i. e., Bidirectional Encoder Representations from Transformers (BERT), to enhance its performance on semantic textual matching tasks.
