Open domain question answering is emerging as a benchmark method of measuring computational systems’ abilities to read, represent, and retrieve knowledge expressed in all of the documents on the web.

In this competition contestants will develop a question answering system that contains all of the knowledge required to answer open-domain questions. There are no constraints on how the knowledge is stored—it could be in documents, databases, the parameters of a neural network, or any other form. However, three competition tracks encourage systems that store and access this knowledge using the smallest number of bytes, including code, corpora, and model parameters. There will also be an unconstrained track, in which the goal is to achieve the best possible question answering performance with no constraints. The best performing systems from each of the tracks will be put to test in a live competition against trivia experts during the NeurIPS 2020 competition track.

All submissions to the memory constrained tracks must be made to the EfficientQA leaderboard before 2020/10/31. Once the leaderboard is closed, the test set inputs will be released and participants will be given until the end of 2020/11/03 to submit predictions to the unconstrained track.

We have provided tutorials on baseline systems as well as a complete guide to making a submission. If you have any questions, please create an issue in this repository.

Competition Overview

This competition will be evaluated using the open domain variant of the Natural Questions question answering task. The questions in Natural Questions are real Google search queries, and each is paired with up to five reference answers. The challenge is to build a question answering system that can generate a correct answer given just a question as input.

Competition Tracks

This competition has four separate tracks. In the unrestricted track contestants are allowed to use arbitrary technology to answer questions, and submissions will be ranked according to the accuracy of their predictions alone.

There are also three restricted tracks in which contestants will have to upload their systems to our servers, where they will be run in a sandboxed environment, without access to any external resources. In these three tracks, the goal is to build:

Human Evaluation

In practice, five reference answers are sometimes not enough—there are a lot of ways in which an answer can be phrased, and sometimes there are multiple valid answers. At the end of this competition’s submission period, predictions from the best performing systems will be checked by humans. The final ranking will be performed on the basis of this human eval.

Baseline Systems

We have provided a tutorial for getting started with several baseline systems that either generate answers directly, from a neural network, or extract them from a corpus of text. You can find the tutorial here.
