Integrating Logical Rules Into Neural Multi-Hop Reasoning for Drug Repurposing

2020 · arXiv (Cornell University)

The graph structure of biomedical data differs from those in typical knowledge graph benchmark tasks. A particular property of biomedical data is the presence of long-range dependencies, which can be captured by patterns described as …

TLogic: Temporal Logical Rules for Explainable Link Forecasting on Temporal Knowledge Graphs

2022 · Proceedings of the AAAI Conference on Artificial Intelligence

Conventional static knowledge graphs model entities in relational data as nodes, connected by edges of specific relation types. However, information and knowledge evolve continuously, and temporal dynamics emerge, which are expected to influence future situations. …
