Abstract
Next-Generation Sequencing has revolutionized the study of genetic mutations, enabling large-scale investigations into their roles in disease development. However, extracting meaningful insights from the vast amount of biomedical literature remains a complex challenge that cannot be addressed manually. In this paper, we present pre-trained models (PTMs) for the automatic extraction of relations from biomedical text, specifically targeting the variant-phenotype domain. Our evaluation on the SNPPhenA corpus demonstrates that fine-tuning small BERT-based models, particularly DeBERTa, yields strong performance, approaching the current state-of-the-art (SOTA). Additionally, our results indicate that carefully fine-tuning Google's Gemini Pro 1.0 outperforms the existing SOTA for both sentence-level tasks (where the model processes only the target sentence) and abstract-level tasks (where the model processes the entire abstract).
This work presents a scalable, reproducible framework for evaluating, optimizing, and interpreting LLMs for biomedical knowledge extraction, with a focus on gene–gene regulatory relation prediction, pathway component recognition, multimodal pathway figure understanding, and automated prompt optimization.
This paper investigates the effectiveness of specializing ultra-compact language models for clinical embedding generation, utilizing the EmbeddingGemma 300M as the base model, and demonstrates the feasibility of performing fine-tuning on entry-level hardware.
The proposed methodology selects and preprocesses a large corpus of scientific articles on malaria, and then annotates them with entities of clinical significance, and leverages BioBERT, a state-of-the-art pre-trained language model, to encode the textual data into context-aware representations.
A critic-based verification mechanism where a second “critic” prompt reviews and verifies extracted relations is investigated, demonstrating that this approach is highly effective, reducing false positives by 58.5% and achieving 74.1% precision with top models, competitive with supervised methods.
