Abstract
Accurate labeling of relevance between biomedical abstracts is essential for improving information retrieval, semantic similarity modeling, training of ranking systems and other Natural Language Processing tasks. However, manual annotations are time-consuming, labor intensive and costly. Studies show that large language models (LLMs) can facilitate automated annotation, but their performance still falls short of human expert-level accuracy, especially in domain-specific tasks. It has been shown that combining annotations from multiple non-expert annotators can achieve performance comparable to, or even exceeding, that of trained experts. Based on this evidence, we treat AI-generated annotations as contributions from non-expert annotators and combine them using Learning to Rank framework. Our results show significant improvement in overall annotation quality. The proposed method looks promising to reduce reliance on human annotation while maintaining reliable performance for large-scale biomedical applications.- Anthology ID:
