APPTeK: Agent-Based Predicate Prediction in Temporal Knowledge Graphs

no code implementations27 Oct 2021 Christian M. M. Frey, Yunpu Ma, Matthias Schubert

In temporal Knowledge Graphs (tKGs), the temporal dimension is attached to facts in a knowledge base resulting in quadruples between entities such as (Nintendo, released, Super Mario, Sep-13-1985), where the predicate holds within a time interval or at a timestamp.

SEA: Graph Shell Attention in Graph Neural Networks

no code implementations20 Oct 2021 Christian M. M. Frey, Yunpu Ma, Matthias Schubert

Intuitively, by increasing the number of experts, the models gain in expressiveness such that a node's representation is solely based on nodes that are located within the receptive field of an expert.
