Realistic Re-evaluation of Knowledge Graph Completion Methods: An Experimental Study

1 code implementation18 Mar 2020 Farahnaz Akrami, Mohammed Samiul Saeef, Qingheng Zhang, Wei Hu, Chengkai Li

A more fundamental defect of these models is that the link prediction scenario, given such data, is non-existent in the real-world.

A Benchmarking Study of Embedding-based Entity Alignment for Knowledge Graphs

1 code implementation10 Mar 2020 Zequn Sun, Qingheng Zhang, Wei Hu, Chengming Wang, Muhao Chen, Farahnaz Akrami, Chengkai Li

Recent advancement in KG embedding impels the advent of embedding-based entity alignment, which encodes entities in a continuous embedding space and measures entity similarities based on the learned embeddings.

Relaxing Relationship Queries on Graph Data

1 code implementation24 Feb 2020 Shuxin Li, Gong Cheng, Chengkai Li

We prove that verifying the success of a sub-query turns into finding an entity (called a certificate) that satisfies a distance-based condition about the query entities.

Gradient-Based Adversarial Training on Transformer Networks for Detecting Check-Worthy Factual Claims

1 code implementation18 Feb 2020 Kevin Meng, Damian Jimenez, Fatma Arslan, Jacob Daniel Devasier, Daniel Obembe, Chengkai Li

We present a study on the efficacy of adversarial training on transformer neural network models, with respect to the task of detecting check-worthy claims.

Cross-lingual Entity Alignment via Joint Attribute-Preserving Embedding

1 code implementation16 Aug 2017 Zequn Sun, Wei Hu, Chengkai Li

Our experimental results on real-world datasets show that this approach significantly outperforms the state-of-the-art embedding approaches for cross-lingual entity alignment and could be complemented with methods based on machine translation.
