Adversarial Attacks on Knowledge Graph Embeddings via Instance Attribution Methods

EMNLP 2021main

Despite the widespread use of Knowledge Graph Embeddings (KGE), little is known about the security vulnerabilities that might disrupt their intended behaviour. We study data poisoning attacks against KGE models for link prediction. These attacks craft adversarial additions or deletions at training t…

Poisoning Knowledge Graph Embeddings via Relation Inference Patterns

ACL 2021long

We study the problem of generating data poisoning attacks against Knowledge Graph Embedding (KGE) models for the task of link prediction in knowledge graphs. To poison KGE models, we propose to exploit their inductive abilities which are captured through the relationship patterns like symmetry, inve…
