Generation Challenges 2020

The Generation Challenges are an umbrella event designed to bring together a variety of shared-task efforts that involve the generation of natural language. This year, Generation Challenges will be held during a special session at the 13th International Conference on Natural Language Generation (INLG 2020.

The session will follow the format of previous GenChal results sessions, with presentations of results by the organisers of the generation challenges that are currently running, as well as presentations of proposals for new shared tasks in the Task Proposals Track.


Call for new Shared Task proposals


We invite submissions of papers describing ideas for future shared tasks in the general area of language generation. Proposed tasks can be in the area of core NLG, or in other research areas in which language is generated. Examples include, but are not limited to: data-to-text NLG, text-to-text generation (including MT and summarisation), combining core NLG and MT, combining core NLG and text summarisation, NLG quality estimation, NLG evaluation metrics, and/or generating language from heterogeneous data, including image and video.

Submissions should describe possible future tasks in detail, including information regarding organisers, task description, motivating theoretical interest and/or application context, size and state of completion of data to be used, schedule and evaluation plans.


Instructions for Paper Submissions


Submissions in the Task Proposals Track should be no more than 4 (four) pages long excluding citations, and should follow the guidelines and template files indicated on the ACL 2020 submissions homepage.

Papers should be submitted via softconf. Please make sure you select "Generation Challenge" in the "Submission Type (*)" drop down menu ("Submission Categories" section of the submission page)."


Task Proposal papers should be submitted no later than 30th August 2020.


Submissions will be peer-reviewed by the program committee. As reviewing will not be blind, there is no need to anonymise papers.

This is not intended to be a selective process, since the aim is to discuss new potential shared tasks with INLG delegates. However, the organisers reserve the right to reject proposals which do not fall within the scope of the GenChal initiative, or which do not follow guidelines.

Accepted submissions will be included in the INLG’20 proceedings.
