Structure Aware Negative Sampling in Knowledge Graphs (2020.emnlp-main)

Copied to clipboard

Challenge: Existing methods for learning low-dimensional representations of entities and relations in knowledge graphs employing corruption distributions that generate hard negative samples.
Approach: They propose a structure-aware negative sampling strategy that utilizes the rich graph structure by selecting negative samples from a node’s k-hop neighborhood.
Outcome: The proposed method finds semantically meaningful negatives and is competitive with SOTA approaches while requires no additional parameters nor difficult adversarial optimization.
