Improving and Simplifying Template-Based Named Entity Recognition (2023.eacl-srw)
Copied to clipboard
| Challenge: | Named Entity Recognition (NER) is traditionally approached as a sequence labeling task where a tag is predicted for each token. |
| Approach: | They propose to convert a Named Entity Recognition task into a seq2seq task by generating synthetic sentences using templates. |
| Outcome: | The proposed model outperforms the current state-of-the-art approach in resource-rich, low resource and domain transfer settings and the negative examples play an important role in its performance. |
Argument Mining in Data Scarce Settings: Cross-lingual Transfer and Few-shot Techniques (2024.acl-long)
Copied to clipboard
| Challenge: | Recent work on sequence labelling has explored different strategies to mitigate the lack of manually annotated data for the large majority of the world languages. |
| Approach: | They propose to use the mask objective to exploit the few-shot capabilities of pre-trained language models to improve their performance. |
| Outcome: | The proposed model-transfer outperforms data-transference and fine-tuning outperformed few-shot methods for Argument Mining task. |
Dynamic Knowledge Integration for Evidence-Driven Counter-Argument Generation with Large Language Models (2025.findings-acl)
Copied to clipboard
| Challenge: | Argumentation in natural language processing (NLP) is becoming an indispensable tool in many application domains such as public policy, law, medicine, and education. |
| Approach: | They propose a reconstructed dataset of argument and counter-argument pairs . they propose integrating dynamic external knowledge from the web to improve counter-arguments . |
| Outcome: | The proposed method shows stronger correlation with human judgments compared to reference-based metrics. |
IxaMed at PharmacoNER Challenge 2019 (D19-57)
Copied to clipboard
| Challenge: | The aim of this paper is to present our approach in the PharmacoNER 2019 task. |
| Approach: | They propose to use a Bi-LSTM with a CRF to identify named entities from clinical case studies written in Spanish. |
| Outcome: | The proposed approach achieves the best score (86.81 F-Score) combining pretrained word embeddings of Wikipedia and Electronic Health Records with contextual string embedds. |
