Researchers have introduced STEM, a new framework designed to enhance knowledge graph-based question answering. This approach tackles challenges related to the structural heterogeneity of knowledge graphs and the lack of global perspective in existing reasoning path retrieval methods. STEM reframes multi-hop reasoning as a schema-guided graph search, improving accuracy and evidence completeness in retrieval tasks. AI
