A Rationale-centric Counterfactual Data Augmentation Method for Cross-Document Event Coreference Resolution

NAACL 2024long

Based on Pre-trained Language Models (PLMs), event coreference resolution (ECR) systems have demonstrated outstanding performance in clustering coreferential events across documents. However, the state-of-the-art system exhibits an excessive reliance on the ‘triggers lexical matching’ spurious patte…

Making Pre-trained Language Models Better Continual Few-Shot Relation Extractors

COLING 2024main

Continual Few-shot Relation Extraction (CFRE) is a practical problem that requires the model to continuously learn novel relations while avoiding forgetting old ones with few labeled training data. The primary challenges are catastrophic forgetting and overfitting. This paper harnesses prompt learni…

Generative Prompt Tuning for Relation Classification

EMNLP 2022finding

Using prompts to explore the knowledge contained within pre-trained language models for downstream tasks has now become an active topic. Current prompt tuning methods mostly convert the downstream tasks to masked language modeling problems by adding cloze-style phrases and mapping all labels to verb…
