Knowledge Graph

KEEP (KnowledgE-Enhanced Pathology) is a vision-language foundation model from Shanghai AI Lab / SJTU that systematically integrates disease knowledge into pretraining for cancer diagnosis. Uses a comprehensive disease knowledge graph with 11,454 diseases and 139,143 attributes from DO and UMLS to reorganize millions of pathology image-text pairs into 143,000 semantically structured groups aligned with disease ontology hierarchies. Across 18 public benchmarks (14,000+ WSIs) and 4 institutional rare cancer datasets (926 cases), KEEP consistently outperforms existing foundation models (CHIEF, CONCH, UNI), with substantial gains for rare subtypes (+8.5 pts balanced accuracy vs CONCH on 30 rare brain cancers).

Vision-language foundation models have shown great promise in computational pathology but remain primarily data-driven, lacking explicit integration of medical knowledge. We introduce KEEP, a foundation model that systematically incorporates disease knowledge into pretraining for cancer diagnosis. KEEP leverages a comprehensive disease knowledge graph encompassing 11,454 diseases and 139,143 attributes to reorganize millions of pathology image-text pairs into 143,000 semantically structured groups aligned with disease ontology hierarchies. Across 18 public benchmarks (over 14,000 WSIs) and 4 institutional rare cancer datasets (926 cases), KEEP consistently outperformed existing foundation models, showing substantial gains for rare subtypes.

SciToolAgent is a knowledge-graph-driven scientific agent that integrates multiple computational tools for scientific research. It leverages a knowledge graph to understand tool capabilities and relationships, enabling automated multi-tool workflow composition for complex scientific tasks across domains including bioinformatics, cheminformatics, and materials science.

Scientific research increasingly relies on specialized computational tools, yet effectively utilizing these tools requires substantial domain expertise. While large language models show promise in tool use, they struggle with complex multi-tool workflows. Here we introduce SciToolAgent, a knowledge-graph-driven scientific agent that integrates multiple computational tools for scientific research. By leveraging a knowledge graph to understand tool capabilities and relationships, SciToolAgent enables automated multi-tool workflow composition for complex scientific tasks.
