Copied to clipboard
| Challenge: | toxicity, hate speech, cyberbullying, and cyber-aggression are common themes in social media . authors present a dataset that is limited in size and biased towards offensive language . |
| Approach: | They present an expanded dataset that uses a taxonomy for offensive language identification . they show that using SOLID and OLID yields sizable performance gains . |
| Outcome: | The proposed dataset shows that it performs better than the OLID dataset for two different models. |

| Challenge: | Nowadays, more and more readers consume news online. |
| Approach: | They propose a news platform that displays news grouped into events and generates media profiles that show the general factuality of reporting, the degree of propagandistic content, hyper-partisanship, leading political ideology, general frame of reporting and stance with respect to various claims and topics of a media outlet. |

Segment-Level Diffusion: A Framework for Controllable Long-Form Generation with Diffusion Language Models (2025.acl-long)
Copied to clipboard
| Challenge: | Diffusion models have shown promise in text generation, but often struggle with generating long, coherent, and contextually accurate text. |
| Approach: | They propose a framework that enhances diffusion-based text generation through text segmentation, robust representation training with adversarial and contrastive learning, and improved latent-space guidance. |
| Outcome: | The proposed framework improves diffusion-based text generation and improves scalability and fluency. |

Copied to clipboard
| Challenge: | a number of fact-checking initiatives have been launched, both manual and automatic, but the whole enterprise remains in a state of crisis. |
| Approach: | They propose a multi-task ordinal regression framework that models trustworthiness estimation and political ideology detection of entire news outlets. |
| Outcome: | The proposed model outperforms models that target the problems in isolation. |
