Probing Simile Knowledge from Pre-trained Language Models

ACL 2022long

Simile interpretation (SI) and simile generation (SG) are challenging tasks for NLP because models require adequate world knowledge to produce predictions. Previous works have employed many hand-crafted resources to bring knowledge-related into models, which is time-consuming and labor-intensive. In…

To address this problem, we pr…
