The Challenge

In 2026, the fourteenth BioASQ challenge comprises the following tasks.

Running tasks

BioASQ Task b on Biomedical Semantic QA (involves IR, QA, summarization and more)  US Flag

  • The organizers distribute English biomedical questions written by biomedical experts.
  • The participants provide: relevant articles, snippets, “exact” answers (e.g. named entities), and “ideal” answers (paragraph-sized summaries).
  • Evaluation: both automatic (GMAP, MRR, ROUGE etc.) and manual (by experts).

BioASQ Task Synergy on Biomedical Semantic QA for developing issues US Flag

  • The organizers distribute open questions on developing biomedical topics.
  • The participants provide: relevant articles, snippets, “exact” answers, and “ideal” answers.
  • The biomedical experts assess the responses and provide feedback to the participants to improve their responses.
  • Evaluation: both automatic (GMAP, MRR, ROUGE etc.) and manual (by experts).

BioASQ Task MultiClinSum-2 on Multilingual Clinical Summarization US Flag  US Flag  US Flag  US Flag ...

  • The organizers distribute lengthy clinical case reports written in English, Spanish, French, and Portuguese. Italian, Swedish, or Czech reports are also considered.
  • The participants generate summaries of the clinical case reports.
  • Evaluation: based on comparison with manual summaries of the clinical case reports.

The BioASQ Task MultiClinSum-2 is co-ogranized with the Barcelona Supercomputing Center.


BioASQ Task BioNNE-R on Nested Relation Extraction in Russian and English Russia  UK

  • The organizers distribute biomedical articles in Russian and English with relations involving nested named entities.
  • The participants extract relations involving nested named entities.
  • Evaluation: based on comparison with manual relations involving nested named entities.

The BioASQ Task BioNNE-R is co-ogranized with the Kazan Federal University.


BioASQ Task ElCardioCC on Clinical Coding in Cardiology Greece

  • The organizers distribute discharge letters from Greek hospitals.
  • The participants assign cardiology-related ICD-10 codes at the document level.
  • Evaluation: based on comparison with manual ICD-10 annotations.

The BioASQ Task ElCardioCC is co-ogranized with the Aristotle University of Thessaloniki.


BioASQ Task GutBrainIE on Gut-Brain interplay Information Extraction UK

  • The organizers distribute PubMed abstracts discussing the gut-brain interplay.
  • The participants extract named entities, link them to concepts in a reference ontology, and identify binary relations between entity pairs.
  • Evaluation: based on comparison with manual annotations.

The BioASQ Task GutBrainIE is co-ogranized with the University of Padua.
