Other notes-Task B

We strongly encourage you to go through the guidelines and pay attention to the changes as well as in the format of the answers you will submit.

Task 12B Guidelines

For a comprehensive description of the BioASQ tasks please visit

Task 12B will use benchmark datasets containing development and test questions, in English, along with gold standard (reference) answers. The benchmark datasets are being constructed by a team of biomedical experts from around Europe. Consult BioASQ Deliverable 3.7 for more information on the construction of the benchmark datasets.

Systems may participate in any of the two or, ideally, both phases.
The rest of the guidelines is organized in sections. You can expand a section by clicking on it.
