MEDIQA 2019 - Recognizing Question Entailment (RQE)

ACL-BioNLP Shared Task


The MEDIQA challenge is an ACL-BioNLP 2019 shared task aiming to attract further research efforts in Natural Language Inference (NLI), Recognizing Question Entailment (RQE), and their applications in medical Question Answering (QA).

Recognizing Question Entailment Task (RQE)

The objective of this task is to identify entailment between two questions in the context of QA. We use the following definition of question entailment: “a question A entails a question B if every answer to B is also a complete or partial answer to A” [1]

For the RQE and NLI tasks:

  • The evaluation will be based on Accuracy.
  • For the result submission file, we expect a csv file with the following header:
    pair_id,label (cf. ValSet_Baseline.csv )


1) Each team is allowed to submit a maximum of 5 runs.

2) Please choose a username that represents your team, and update your profile with the following information: First name, Last nam, Affiliation, Address, City, Country.

3) For each run submission, it is mandatory to fill in the submission description field of the submission form with a short description of the methods, tools and resources used for that run.
