Abstract Summary
GutBrainKB is a web platform based on a structured KB to aid clinicians and researchers in studying gut¬Cbrain interactions. It features a 79K-triple KB from expert-annotated literature in the GutBrainIE dataset (BioASQ Lab @ CLEF 2025), offering a reliable resource for exploring the gut-brain axis. Users can explore through natural language and faceted search, investigating entity relationships, accessing scientific literature, and visualizing connections with interactive graphs. GutBrainKB combines a semantically validated KB with an accessible interface, providing an efficient tool for analyzing gut¬Cbrain interactions and their impact on neurological and psychiatric disorders.
