text: "Verifying assertions is an essential part of creating and maintaining knowledge
graphs. Most often, this task cannot be carried out manually due to the sheer
size of modern knowledge graphs. Hence, automatic fact-checking approaches have
been proposed over the last decade. These approaches aim to compute automatically
whether a given assertion is correct or incorrect. However, most fact-checking
approaches are binary classifiers that fail to consider the volatility of some
assertions, i.e., the fact that such assertions are only valid at certain times
or for specific time intervals. Moreover, the few approaches able to predict when
an assertion was valid (i.e., time-point prediction approaches) rely on manual
feature engineering. This paper presents T EMPORAL FC, a temporal fact-checking
approach that uses multiple sources of background knowledge to assess the veracity
and temporal validity of a given assertion. We evaluate T EMPORAL FC\r\non two
datasets and compare it to the state of the art in fact-checking and time-point
prediction. Our results suggest that T EMPORAL FC outperforms the state of the
art on the fact-checking task by 0.13 to 0.15 in terms of Area Under the\r\nReceiver
Operating Characteristic curve and on the time-point prediction task by 0.25 to
0.27 in terms of Mean Reciprocal Rank. Our code is open-source and can be found
at https://github.com/dice-group/TemporalFC."
