- Abstract: A temporal knowledge graph (TKG) stores the events derived from the data
involving time. Predicting events is extremely challenging due to the
time-sensitive property of events. Besides, the previous TKG completion (TKGC)
approaches cannot represent both the timeliness and the causality properties of
events, simultaneously. To address these challenges, we propose a Logic and
Commonsense-Guided Embedding model (LCGE) to jointly learn the time-sensitive
representation involving timeliness and causality of events, together with the
time-independent representation of events from the perspective of commonsense.
Specifically, we design a temporal rule learning algorithm to construct a
rule-guided predicate embedding regularization strategy for learning the
causality among events. Furthermore, we could accurately evaluate the
plausibility of events via auxiliary commonsense knowledge. The experimental
results of TKGC task illustrate the significant performance improvements of our
model compared with the existing approaches. More interestingly, our model is
able to provide the explainability of the predicted results in the view of
causal inference. The source code and datasets of this paper are available at

Temporal knowledge graphs (TKGs) can effectively model the ever-evolving nature of real-world knowledge, and their completeness and enhancement can be achieved by reasoning new events from existing ones.
However, reasoning accuracy is adversely impacted due to an imbalance between new and recurring events in the datasets.
We propose an attention masking-based contrastive event network (AMCEN) with local-global temporal patterns for the two-stage prediction of future events.

We first convert TKGs into a temporal event knowledge graph (TEKG) which has a more explicit representation of time in term of nodes of the graph.
Finally, we introduce conditional probability density functions, associated with the logical rules involving the query interval, using which we arrive at the time prediction.
