Description

Dataset for a Food Ontology Integrating HUMMUS and Open Food Facts with Extended User Attributes

This dataset supports a food ontology that semantically integrates two existing resources: the HUMMUS knowledge graph (focused on recipes, users, and reviews) and Open Food Facts (OFF, focused on nutritional information for packaged foods). In addition to aligning entities and concepts across the two sources, the ontology introduces new user-specific attributes to enable more fine-grained modeling of food preferences, constraints, and behaviors. The resource is intended for use in research on personalized nutrition, food recommendation systems, and knowledge-based AI applications.
