Amazon is offering student bursaries to participants for FEVER 2019 workshop.

Please email us your CV and a short paragraph stating why you would like to be considered to with the title "Application for student bursary". Please send your applications by midnight PST on Sunday 6th October 2019.


The results of the Shared Task are out!


With billions of individual pages on the web providing information on almost every conceivable topic, we should have the ability to collect facts that answer almost every conceivable question. However, only a small fraction of this information is contained in structured sources (Wikidata, Freebase, etc.) – we are therefore limited by our ability to transform free-form text to structured knowledge. There is, however, another problem that has become the focus of a lot of recent research and media coverage: false information coming from unreliable sources. [1] [2]

Last year, in an effort to jointly address both problems, we organised the first workshop on Fact Extraction and VERification (FEVER) at EMNLP 2018. For the second workshop, in addition to extracting facts and verifying them, we would also like to focus on adversarial learning by generating adversarial examples that fool these systems. The FEVER 2.0 Shared Task will build upon work from the first shared task in a Build it Break it Fix it setting.

The second workshop on Fact Extraction and VERification (FEVER 2.0) will be held at EMNLP-IJCNLP 2019 in Hong Kong. Just like in FEVER 1.0, we are hosting two tracks and are seeking papers on topics relating to fact checking as well as system descriptions of entries to the FEVER 2.0 Shared Task. At the workshop, we will host invited talks, presentations of submitted papers and announce the results and winners of the FEVER 2.0 Shared Task.

How to Participate in the challenge

1) Join the Slack Group

2) Register on our Codalab page

Data can be downloaded and submissions evaluated on the Codalab competition page

3) Develop your Systems

The shared task guidelines are available on the task page.

A simple baseline described in this NAACL2018 paper preprint, the scorer code, as well as the annotation UI source code are available on our GitHub page.

4) (July) Evaluate on the Test Set and Submit your System Descriptions

We will open the blind test set for scoring in July and accept system description papers on Softconf for the workshop at EMNLP2018. More details to follow soon.
