STEM: Structure-Tracing Evidence Mining for Knowledge Graphs-Driven Retrieval-Augmented Generation

In three linesSTEM proposes a framework for Knowledge Graph-based Question Answering (KGQA) that reframes multi-hop reasoning as schema-guided graph search. Uses a Semantic-to-Structural Projection pipeline and Triple-Dependent GNN to generate a Global Guidance Subgraph. Achieves SOTA on multiple multi-hop benchmarks.
