Multilingual Extraction and Categorization of Lexical Collocations with Graph-aware Transformers (2022.starsem-1)
Copied to clipboard
| Challenge: | lexical collocations exhibit varying degrees of frozenness due to their varying degree of frozenncy. |
| Approach: | They propose a sequence tagging BERT-based model enhanced with a graph-aware transformer architecture and evaluate the task of collocation recognition in context. |
| Outcome: | The proposed model encoding syntactic dependencies is useful, and provides insights on differences in collocation typification in English, Spanish and French. |
GPT-HateCheck: Can LLMs Write Better Functional Tests for Hate Speech Detection? (2024.lrec-main)
Copied to clipboard
| Challenge: | HateCheck test cases are generic and have simplistic sentence structures that do not match the real-world data. |
| Approach: | They propose a framework to generate more diverse and realistic functional tests from scratch by instructing large language models. |
| Outcome: | The proposed framework generates more diverse and realistic functional tests from scratch by instructing large language models (LLMs). |
Emo Pillars: Knowledge Distillation to Support Fine-Grained Context-Aware and Context-Less Emotion Classification (2025.findings-acl)
Copied to clipboard
| Challenge: | a recent study shows that sentiment analysis datasets lack context in which an opinion was expressed and are limited by a few emotion categories. |
| Approach: | They propose to ground an LLM-based model into a corpus of narratives to generate stories-character-centered utterances with unique contexts over 28 emotion classes. |
| Outcome: | The proposed model generates non-repetitive story-character-centered utterances with unique contexts over 28 emotion classes. |
