Do Similar Entities have Similar Embeddings?

1 code implementation16 Dec 2023 Nicolas Hubert, Heiko Paulheim, Armelle Brun, Davy Monticolo

A common tacit assumption is the KGE entity similarity assumption, which states that these KGEMs retain the graph's structure within their embedding space, \textit{i. e.}, position similar entities within the graph close to one another.

Beyond Transduction: A Survey on Inductive, Few Shot, and Zero Shot Link Prediction in Knowledge Graphs

no code implementations8 Dec 2023 Nicolas Hubert, Pierre Monnin, Heiko Paulheim

Consequently, a larger body of works focuses on the completion of missing information in KGs, which is commonly referred to as link prediction (LP).

Treat Different Negatives Differently: Enriching Loss Functions with Domain and Range Constraints for Link Prediction

2 code implementations1 Mar 2023 Nicolas Hubert, Pierre Monnin, Armelle Brun, Davy Monticolo

In an extensive and controlled experimental setting, we show that the proposed loss functions systematically provide satisfying results which demonstrates both the generality and superiority of our proposed approach.

Sem@$K$: Is my knowledge graph embedding model semantic-aware?

2 code implementations13 Jan 2023 Nicolas Hubert, Pierre Monnin, Armelle Brun, Davy Monticolo

That is why, in this paper, we extend our previously introduced metric Sem@K that measures the capability of models to predict valid entities w. r. t.
