BioASQ 14b

Question-type-aware LLM pipeline with multi-agent collaboration achieves top factoid performance on BioASQ 14b

Researchers present a question-type-specific LLM framework for the BioASQ 14b biomedical QA challenge, applying distinct inference strategies to yes/no, factoid, and list questions rather than a single unified approach. For list questions, a multi-agent architecture handles evidence extraction, candidate generation, verification, and aggregation collaboratively. The framework achieved first place in the factoid subtask of Batch 4 in the official BioASQ 14b evaluation, demonstrating competitive performance across multiple batches.
