Unifying Cross-Lingual Semantic Role Labeling with Heterogeneous Linguistic Resources (2021.naacl-main)
Copied to clipboard
| Challenge: | Using cross-lingual techniques to perform Semantic Role Labeling (SRL) has been limited by the fact that each language adopts its own linguistic formalism . |
| Approach: | They propose a unified model to perform cross-lingual SRL over heterogeneous linguistic resources. |
| Outcome: | The proposed model is able to annotate a sentence in a single forward pass with all the inventories it was trained with, providing a tool for the analysis and comparison of linguistic theories across different languages. |
Handling Ontology Gaps in Semantic Parsing (2024.starsem-1)

| Challenge: | Existing methods to detect hallucinations in closed-ontology models are limited by ontology gaps. |
| Approach: | They propose a framework for stimulating and analyzing NSP model hallucinations . they propose 'hallucination simulation framework' to detect hallucinosities in presence of ontology gaps . |
| Outcome: | The proposed framework improves the F1-Score and the IQ Pro benchmark datasets. |
DanteLLM: Let’s Push Italian LLM Research Forward! (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing models for large language processing in the English language are limited in resources and evaluation tools for non-English languages. |
| Approach: | They propose a benchmark and an open LLM Leaderboard to evaluate LLMs’ performance in Italian and propose 'DanteLLM' it is the most performant LLM in the world, with improvements of up to 6 points . |
| Outcome: | The proposed model outperforms existing models in Italian and offers a blueprint for the development and evaluation of LLMs in other languages. |
