Data-Efficient Concept Extraction from Pre-trained Language Models for Commonsense Explanation Generation (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods to extract concepts from pre-trained language models are not suitable for commonsense explanation generation. |
| Approach: | They propose a method to extract the key explanation concept from pre-trained language models by fine-tuning it with 20% training data and using a metric to evaluate the retrieved concepts. |
| Outcome: | The proposed method improves evaluation metrics over pre-trained language models and the existing models. |
Few-shot Named Entity Recognition via Superposition Concept Discrimination (2024.lrec-main)
Copied to clipboard
| Challenge: | Few-shot named entity recognition (NER) aims to identify entities of target types with limited number of illustrative instances. |
| Approach: | They propose a superposition concept discriminator which solves the intrinsic generalization problem by an active learning paradigm. |
| Outcome: | The proposed model significantly improves few-shot named entity recognition (FS-NER) with minimal additional efforts. |
