+# Dataset Card for BioASQ Task B
+
+## Dataset Description
+
+- **Homepage:** http://participants-area.bioasq.org/datasets/
+- **Pubmed:** True
+- **Public:** False
+- **Tasks:** QA
+
+
+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'

+by a team of biomedical experts. The participants have to respond with relevant
+concepts, articles, snippets and RDF triples, from designated resources, as well
+as exact and 'ideal' answers.

+- 500 new questions added from BioASQ5
+    - 48 pairs of questions with identical bodies have been merged into one
+    question having only one question-id, but all the documents, snippets,
+    concepts, RDF triples and answers of both questions of the pair.
+        - This normalization lead to the removal of 48 deprecated question
+        ids [2] from the dataset and to the update of the 48 remaining
+        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
+        the question body. The change of type lead to corresponding changes
+        in exact answers existence and format : 54fc4e2e6ea36a810c000003,

+    - In lists of ideal answers, documents, snippets, concepts and RDF triples
+    any duplicate identical elements have been removed.
+    - Ideal answers in format of one string have been converted to a list with
+    one element for consistency with cases where more than one golden ideal
+    answers are available. (i.e. "ideal_ans1" converted to ["ideal_ans1"])
+    - For yesno questions: All exact answers have been normalized to "yes" or
+    "no" (replacing "Yes", "YES" and "No")
+    - For factoid questions: The format of the exact answer was normalized to a
+    list of strings for each question, representing a set of synonyms
+    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`] ...]).
