UCL Machine Reading Group: Four Factor Framework For Fact Finding (HexaF)
Open accessAbstract
In this paper we describe our 2 nd place FEVER shared-task system that achieved a FEVER score of 62.52% on the provisional test set (without additional human evaluation), and 65.41% on the development set.Our system is a four stage model consisting of document retrieval, sentence retrieval, natural language inference and aggregation.Retrieval is performed leveraging task-specific features, and then a natural language inference model takes each of the retrieved sentences paired with the claimed fact.The resulting predictions are aggregated across retrieved sentences with a Multi-Layer Perceptron, and re-ranked corresponding to the final prediction.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
Most literature leverages Wikipedia as the knowledge source, which is only a small part of world knowledge.
“Most of the literature leverages Wikipedia as the knowledge source [135, 249, 300], which is only a small part of world knowledge.”
From Survey of Hallucination in Natural Language Generation (2023) · cites this paper as [300]
The Introduction describes FEVER as using a corpus of Wikipedia articles, and §2 describes this paper’s system retrieving evidence from them. The paper is therefore an example of work using Wikipedia as a knowledge source, but it does not establish that most literature does so or discuss Wikipedia’s share of world knowledge.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
