Loss-Based Active Learning for Neural Abstractive Summarization

Loss-Based Active Learning for Neural Abstractive Summarization proposes LOBSTER, an active learning framework that selects unlabeled documents similar to the model’s high‑loss training examples to correct specific weaknesses. The method is tailored for abstractive summarization, addressing instability and computational bottlenecks seen in prior work. Experiments on three benchmark datasets and two backbone models show that LOBSTER matches or surpasses state‑of‑the‑art performance while speeding up query selection by up to 665×.

Abstracts or full text? Evaluating input scope and computational efficiency in biomedical lay summarization

The study investigates whether using only abstracts of biomedical articles can produce lay summaries that match the quality of those derived from full texts, and whether few‑shot learning can replace fine‑tuning large language models. Experiments on two public datasets with two recent models show that abstract‑based summarization outperforms full‑text approaches in readability, factual consistency, semantic similarity, and runtime efficiency. Abstract fine‑tuning is 4.70 times faster and abstract zero‑ and few‑shot prompting is 5.31 times faster than full‑text methods, indicating that abstract‑based prompting reduces computational cost while preserving summary quality.
