MESAQA: A Dataset for Multi-Span Contextual and Evidence-Grounded Question Answering (2025.coling-main)
Copied to clipboard
| Challenge: | Existing question answering systems focus on extracting answers from single spans, but real-world scenarios require synthesizing information from multiple spans. |
| Approach: | They propose a dataset that leverages the MASH-QA dataset and large language models (LLMs) to ensure that each Q/A pair requires considering all selected spans. |
| Outcome: | The proposed method enables the model to answer multiple Q/A pairs in a single span, while ensuring that all selected spans are considered. |
BILLY: Steering Large Language Models via Merging Persona Vectors for Creative Generation (2026.eacl-long)
Copied to clipboard
| Challenge: | Multi-LLM systems enhance creativity of large language models by simulating human collective intelligence but suffer from significant drawbacks, such as high computational costs and inference latency. |
| Approach: | They propose a training-free framework that captures the benefits of multi-LLM collaboration by extracting and blending multiple distinct persona vectors directly in the model’s activation space. |
| Outcome: | The proposed framework surpasses model prompting and traditional multi-LLM approaches while significantly reducing inference time and computational costs. |
