MEDIQA 2021 - Multi-Answer Summarization (MAS)

ACL-BioNLP Shared Task


πŸ•΅οΈ Introduction

MEDIQA 2021 tackles three summarization tasks in the medical domain:

In this shared task, we will also explore the use of different evaluation metrics for summarization.

MEDIQA 2021 will be organized at the NAACL-BioNLP 2021 workshop.


Different answers can bring complementary perspectives that are likely to benefit the users of QA systems. The goal of this task is to promote the development of multi-answer summarization approaches that could solve simultaneously the aggregation and summarization problems posed by multiple relevant answers to a medical question. 

πŸ’Ύ Datasets

  • Training Data: The MEDIQA-AnS Dataset [4] could be used for training. Participants can use available external resources. 

  • Validation and Test Sets: The original answers are generated by the medical QA system CHiQA [5] which searches for answers from only trustworthy medical information sources [6]. The summaries are manually created by medical experts. 

  • The validation set is available here: https://github.com/abachaa/MEDIQA2021/tree/main/Task2

  • The test set will be available for the registered participants under the Resources Section.


The registration & data usage agreement form is available under the Resources section of the AIcrowd projects. The form covers the three tasks. You can download it from any of the three MEDIQA projects: QS@AIcrowdMAS@AIcrowd & RRS@AIcrowd.
To register, you need to complete, sign, and upload the form. When approved, you will be able to download the official test sets and to submit your runs on the AIcrowd submission systems.

πŸ–Š  Evaluation Metrics

ROUGE will be used as the main metric to rank the participating teams, but we will also use several evaluation metrics more adapted to each task. 

πŸš€ Submission format

- Format: ID [tab] Summary

-- Task 1 & Task 2 => question_id [tab] summary 

-- Task 3 => study_id [tab] summary 

- The summary must fit in one line (no line breaks). 

πŸ“œ Rules

1) Each team is allowed to submit a maximum of 10 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.

4) The final results will not be considered official until a working notes paper with the full description of the methods is submitted.
