Knowledge Graph Reasoning with Graph Neural Networks
Explore knowledge graph reasoning with graph neural networks in this 26-minute talk by Zhaocheng Zhu from the University of Montreal and Mila. Dive into the fundamental problem of predicting answers to queries by reasoning over existing facts in knowledge graphs. Learn about two innovative approaches: Neural Bellman-Ford Networks (NBFNet) for single-hop reasoning and Graph Neural Network Query Executor (GNN-QE) for multi-hop queries. Discover how these models relate to traditional symbolic methods while addressing missing links in knowledge graphs. Gain insights into the visualization of intermediate reasoning steps, enhancing understanding of the process. Cover topics such as inductive settings, path representations, efficient computation, first-order logic queries, and fuzzy logic operations. Understand the applications of knowledge graphs in natural language understanding, recommender systems, and drug discovery.
