PromptMR: Adapting Prompt Learning to Metonymy Resolution 😃

How many surprises it can bring us when adapting the Prompt Learning paradigm to the Metonymy Resolution task?

⭐ ⭐ ⭐ ⭐ ⭐

PromptMRs are the first also systematic explorations that adapt the prompt-tuning paradigm to the NLP Metonymy Resolution research area.

> For Template Engineering in Prompting, apart from the attempt at Discrete Template Construction strategies (i.e. manual-crafted template),
we also explore the potentials of the Automated Continuous Template Construction strategy.

> For Answer Engineering in Prompting, apart from the attempt of Discrete Answer Search (i.e. manual-crafted mapping strategy that uses the 
answer words set to predict final labels), we further explore the Continuous Answer Automatic Search strategy.

> Extensive experiments prove that when compared with previous SOTA methods for Metonymy Resolution, the Prompt Learning methods are still
sufficiently competitive. Concretely, our Prompt Learning based Metonymy Resolution methods perform fairly well in terms of training convergence
efficiency and final classification performance over previous SOTA methods, both in data-sufficient (i.e. full-data training) and data-scarce 
(i.e. few-shot) scenarios.

The left shows the routine architecture of Prompt Learning, and the right represents the specific implementation of our first exploration, PromptMR-base, based on a Metonymy Resolution example of the sentence “Belgium beat Turkey 2 - 1.”.
