parsa-abbasi / RAGATv2

An enhanced model known as RAGATv2 which is built upon the structure of the Relation Aware Graph Attention Network (RAGAT)

RAGAT: Relation Aware Graph Attention Network for Knowledge Graph Completion

Overview

We propose a Relation Aware Graph ATtention network (RAGAT) that constructs separate message functions for different relations. Specifically, we introduce relation specific parameters to augment the expressive capability of message functions, which enables the model to extract relational information in parameter space. To validate the effect of relation aware mechanism, RAGAT is implemented with a variety of relation aware message functions. Experiments show RAGAT outperforms state-of-the-art link prediction baselines on standard FB15k-237 and WN18RR datasets.
