Phrase-level attention network for few-shot inverse relation classification in knowledge graph

open access: yes, 2023
Relation classification aims to recognize semantic relation between two given entities mentioned in the given text. Existing models have performed well on the inverse relation classification with large-scale datasets, but their performance drops ...

Edge-Featured Graph Attention Network

open access: yesCoRR, 2021
Lots of neural network architectures have been proposed to deal with learning tasks on graph-structured data. However, most of these models concentrate on only node features during the learning process. The edge features, which usually play a similarly important role as the nodes, are often ignored or simplified by these models.

Dual-Attention Graph Convolutional Network [PDF]

open access: yes, 2020
Graph convolutional networks (GCNs) have shown the powerful ability in text structure representation and effectively facilitate the task of text classification. However, challenges still exist in adapting GCN on learning discriminative features from texts due to the main issue of graph variants incurred by the textual complexity and diversity.

Graph Attention Networks with Positional Embeddings [PDF]

open access: yes, 2021
Graph Neural Networks (GNNs) are deep learning methods which provide the current state of the art performance in node classification tasks. GNNs often assume homophily -- neighboring nodes having similar features and labels--, and therefore may not be at their full potential when dealing with non-homophilic graphs.

Graph Decipher: A transparent dual‐attention graph neural network to understand the message‐passing mechanism for the node classification

open access: yes, 2022
Graph neural networks (GNNs) can be effectively applied to solve many real-world problems across widely diverse fields. Their success is inseparable from the message-passing mechanisms evolving over the years.

SEA: Graph Shell Attention in Graph Neural Networks

open access: yes, 2023
A common issue in Graph Neural Networks (GNNs) is known as over-smoothing. By increasing the number of iterations within the message-passing of GNNs, the nodes' representations of the input graph align with each other and become indiscernible. Recently, it has been shown that increasing a model's complexity by integrating an attention mechanism yields ...
