Temporal knowledge graph reasoning triggered by memories

open access: yesApplied Intelligence, 2023
Inferring missing facts in temporal knowledge graphs is a critical task and has been widely explored. Extrapolation in temporal reasoning tasks is more challenging and gradually attracts the attention of researchers since no direct history facts for prediction.

Large scale distributed spatio-temporal reasoning using real-world knowledge graphs [PDF]

open access: yes, 2019
Most of the existing work in the field of Qualitative Spatial Temporal Reasoning (QSTR) has focussed on comparatively small constraint networks that consist of hundreds or at most thousands of relations. Recently we have seen the emergence of much larger

MOMENT: temporal meta-fact generation and propagation in knowledge graphs [PDF]

open access: yes, 2020
International audienceThis paper deals with the problem of temporal meta-fact generation in RDF knowledge graphs (KGs). These temporal meta-facts represent the time validity of facts, for instance, is valid for the period [2008..2016].
