BioASQ at CLEF2026: The Fourteenth Edition of the Large-Scale Biomedical Semantic Indexing and Question Answering Challenge

Over the past thirteen years, the large-scale biomedical semantic indexing and question-answering challenge (BioASQ) has consistently driven the advancement of methods and tools that enhance access to the rapidly growing body of scientific resources in the biomedical domain. BioASQ offers a unique common testbed where research teams worldwide can evaluate and compare innovative approaches for accessing biomedical knowledge by organizing shared tasks on an annual basis and providing respective benchmark datasets that represent the real information needs of biomedical experts . The fourteenth version of BioASQ (BioASQ14) will be held as an evaluation Lab in the context of CLEF2026, providing six tasks: (i) Task b on biomedical semantic question answering. (ii) Task Synergy on question answering for developing biomedical topics. (iii) Task MultiClinSum-2 on multilingual clinical summarization. (iv) Task BioNNE-R on nested relation extraction in Russian and English. (v) Task ELCardioCC on clinical coding in cardiology. (vi) Task GutBrainIE on gut-brain interplay information extraction. Through its six shared tasks, BioASQ14 challenges the research community to develop methods that go beyond the current state of the art, fostering innovative approaches that enable efficient and precise access to biomedical knowledge while pushing the research frontier forward.
