| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary This paper proposes a novel approach to inductive relation prediction, focusing on learning the representation of subgraphs induced from target links. The existing methods mainly rely on graph neural networks (GNNs) for implicit rule-mining, but these approaches fail to differentiate between the target link and other links during message passing. This results in subgraph representations containing irrelevant rule information, reducing the reasoning performance and limiting real-world applications. To tackle this issue, the authors introduce a single-source edge-wise GNN model, dubbed REST (Rule-induced Subgraph Representations), which encodes relevant rules and eliminates irrelevant ones within the subgraph. The proposed initialization approach guarantees the relevance of mined rules, while RNN-based functions for edge-wise message passing model the sequential property of mined rules. REST is shown to be a simple, effective, and theoretically supported approach that learns rule-induced subgraph representations without node labeling, significantly accelerating subgraph preprocessing time. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary This paper helps us better predict relationships between entities in changing knowledge graphs. Currently, we use graph neural networks (GNNs) to learn about these relationships, but this method has a major flaw: it can’t tell the difference between the relationship we’re interested in and other relationships. This makes the learned information less useful for real-world applications. The authors of this paper propose a new approach that fixes this problem by focusing on the specific relationship we want to predict. They call their method REST, which stands for Rule-induced Subgraph Representations. It’s a simple and effective way to learn about relationships without needing extra labels or preprocessing time. |
