Negative Sampling with Adaptive Denoising Mixup for Knowledge Graph Embedding

1 code implementation15 Oct 2023 Xiangnan Chen, Wen Zhang, Zhen Yao, Mingyang Chen, Siliang Tang

Most existing negative sampling methods assume that non-existent triples with high scores are high-quality negative triples.

A Comprehensive Study on Knowledge Graph Embedding over Relational Patterns Based on Rule Learning

1 code implementation15 Aug 2023 Long Jin, Zhen Yao, Mingyang Chen, Huajun Chen, Wen Zhang

Though KGE models' capabilities are analyzed over different relational patterns in theory and a rough connection between better relational patterns modeling and better performance of KGC has been built, a comprehensive quantitative analysis on KGE models over relational patterns remains absent so it is uncertain how the theoretical support of KGE to a relational pattern contributes to the performance of triples associated to such a relational pattern.

NeuralKG-ind: A Python Library for Inductive Knowledge Graph Representation Learning

1 code implementation28 Apr 2023 Wen Zhang, Zhen Yao, Mingyang Chen, Zhiwei Huang, Huajun Chen

Since the dynamic characteristics of knowledge graphs, many inductive knowledge graph representation learning (KGRL) works have been proposed in recent years, focusing on enabling prediction over new entities.

Entity-Agnostic Representation Learning for Parameter-Efficient Knowledge Graph Embedding

1 code implementation3 Feb 2023 Mingyang Chen, Wen Zhang, Zhen Yao, Yushan Zhu, Yang Gao, Jeff Z. Pan, Huajun Chen

In our proposed model, Entity-Agnostic Representation Learning (EARL), we only learn the embeddings for a small set of entities and refer to them as reserved entities.

Analogical Inference Enhanced Knowledge Graph Embedding

1 code implementation3 Jan 2023 Zhen Yao, Wen Zhang, Mingyang Chen, Yufeng Huang, Yi Yang, Huajun Chen

And in AnKGE, we train an analogy function for each level of analogical inference with the original element embedding from a well-trained KGE model as input, which outputs the analogical object embedding.

Meta-Learning Based Knowledge Extrapolation for Knowledge Graphs in the Federated Setting

1 code implementation10 May 2022 Mingyang Chen, Wen Zhang, Zhen Yao, Xiangnan Chen, Mengxiao Ding, Fei Huang, Huajun Chen

We study the knowledge extrapolation problem to embed new components (i. e., entities and relations) that come with emerging knowledge graphs (KGs) in the federated setting.
