127
+ ### Dataset Summary
128
+
129
+ With billions of individual pages on the web providing information on almost every conceivable topic, we should have
130
+ the ability to collect facts that answer almost every conceivable question. However, only a small fraction of this
131
+ information is contained in structured sources (Wikidata, Freebase, etc.) – we are therefore limited by our ability to
132
+ transform free-form text to structured knowledge. There is, however, another problem that has become the focus of a lot
133
+ of recent research and media coverage: false information coming from unreliable sources.
134
+
135
+ The FEVER workshops are a venue for work in verifiable knowledge extraction and to stimulate progress in this direction.
136
+
137
+ - FEVER Dataset: FEVER (Fact Extraction and VERification) consists of 185,445 claims generated by altering sentences
138
+ extracted from Wikipedia and subsequently verified without knowledge of the sentence they were derived from. The claims
139
+ are classified as Supported, Refuted or NotEnoughInfo. For the first two classes, the annotators also recorded the
140
+ sentence(s) forming the necessary evidence for their judgment.
141
+
142
+ - FEVER 2.0 Adversarial Attacks Dataset: The FEVER 2.0 Dataset consists of 1174 claims created by the submissions of
143
+ participants in the Breaker phase of the 2019 shared task. Participants (Breakers) were tasked with generating
144
+ adversarial examples that induce classification errors for the existing systems. Breakers submitted a dataset of up to
145
+ 1000 instances with equal number of instances for each of the three classes (Supported, Refuted NotEnoughInfo). Only
146
+ novel claims (i.e. not contained in the original FEVER dataset) were considered as valid entries to the shared task.
147
+ The submissions were then manually evaluated for Correctness (grammatical, appropriately labeled and meet the FEVER
148
+ annotation guidelines requirements).
149
+
150
+ ### Supported Tasks and Leaderboards
151
+
152
+ The task is verification of textual claims against textual sources.
153
+
154
+ When compared to textual entailment (TE)/natural language inference, the key difference is that in these tasks the
155
+ passage to verify each claim is given, and in recent years it typically consists a single sentence, while in
156
+ verification systems it is retrieved from a large set of documents in order to form the evidence.
157
+
158
+ ### Languages
159
+
160
+ The dataset is in English.
