+
+## Dataset Description
+
+- **Homepage:** http://participants-area.bioasq.org/datasets/
+- **Pubmed:** True
+- **Public:** False
+- **Tasks:** Question Answering
+
+
+The BioASQ corpus contains multiple question
+answering tasks annotated by biomedical experts, including yes/no, factoid, list,
+and summary questions. Pertaining to our objective of comparing neural language
+models, we focus on the the yes/no questions (Task 7b), and leave the inclusion
+of other tasks to future work. Each question is paired with a reference text
+containing multiple sentences from a PubMed abstract and a yes/no answer. We use
+the official train/dev/test split of 670/75/140 questions.
+
+See 'Domain-Specific Language Model Pretraining for Biomedical
+Natural Language Processing'

+        questions [3].
+        - In cases where a pair of questions with identical bodies had some
+        inconsistency (e.g. different question type), the inconsistency has
+        been solved merging the pair manually consulting the BioASQ expert team.
+    - 12 questions were revised for various confusions that have been
+    identified
+        - In 8 questions the question type has been changed to better suit to

+    answering the question (i.e. [`ans1`, `syn11`, ... ]).
+    - For list questions: The format of the exact answer was normalized to a
+    list of lists. Each internal list represents one element of the answer
+    as a set of synonyms
+    (i.e. [[`ans1`, `syn11`, `syn12`], [`ans2`], [`ans3`, `syn31`] ...]).
