PhotoGraph is a claim-centric, spatially and temporally aware knowledge graph system for personal photo management and photobook co-creation.
It represents AI-generated observations as evidence-grounded claims, capturing provenance, confidence, and lifecycle information. The system supports contextual photo retrieval, event organization, human-in-the-loop refinement, and fact-grounded storytelling.
🚧 This repository will be uploaded soon.
