New TKGE model BSCA enhances fact inference with biquaternionic space and attention

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new Temporal Knowledge Graph Embedding (TKGE) model called Biquaternionic Space with Complex-valued Attention (BSCA). This model aims to improve the inference of missing facts in evolving knowledge graphs by utilizing a unified biquaternionic framework that combines circular and hyperbolic rotations. BSCA incorporates a complex-valued attention mechanism to adaptively fuse time-conditioned and relation-conditioned entity representations, allowing them to vary with temporal and relational context. Experiments demonstrated that BSCA achieved competitive performance across five benchmark datasets, notably showing the largest improvement on the GDELT dataset with an MRR of 52.1%, surpassing the strongest baseline by 14 percentage points.

    Biquaternionic Space with Complex-valued Attention for Temporal Knowledge Graph Completion

    arXiv:2609.14279v1 Announce Type: cross Abstract: Temporal knowledge graph embedding (TKGE) models infer missing facts in knowledge graphs that evolve over time. Many existing models use a single geometric space, which can limit their ability to represent diverse relational patte…
