Graphlets as Building Blocks for Structural Vocabulary in Knowledge Graph Foundation Models

Kossi Amouzouvi, Robert Wardenga, Jens Lehmann +1

Foundation models excel at language, where sentences become tokens, and vision, where images become pixels, because both reduce to discrete symbols on a shared, fixed grid. Knowled…
