ROG: Retrieval-Augmented LLM Reasoning for Complex First-Order Queries over Knowledge Graphs
Ziyan Zhang, Chao Wang, Zhuo Chen +2
Answering first-order logic (FOL) queries over incomplete knowledge graphs (KGs) is difficult, especially for complex query structures that compose projection, intersection, union,…

A Large Language Model Based Method for Complex Logical Reasoning over Knowledge Graphs
Ziyan Zhang, Chao Wang, Zhuo Chen +3
Reasoning over knowledge graphs (KGs) with first-order logic (FOL) queries is challenging due to the inherent incompleteness of real-world KGs and the compositional complexity of l…

Power Transformer Fault Prediction Based on Knowledge Graphs
Chao Wang, Zhuo Chen, Ziyan Zhang +2
In this paper, we address the challenge of learning with limited fault data for power transformers. Traditional operation and maintenance tools lack effective predictive capabiliti…
