SPE: Symmetrical Prompt Enhancement for Fact Probing (2022.emnlp-main)
Copied to clipboard
| Challenge: | Recent work probes PLMs for the extent of factual knowledge through prompts . however, these methods do not consider symmetry of the task: object and subject prediction. |
| Approach: | They propose a continuous prompt-based method that leverages symmetry of the task by constructing symmetrical prompts for subject and object prediction. |
| Outcome: | The proposed method improves on a popular factual probing dataset on lAMA. |
