Table 3_Ontology-based dietary recommendation system for Chinese children and adolescents:

An ontology-driven dietary recommendation system for Chinese children and adolescents was evaluated in two pilot settings. The system, developed by Zhiyu Zhang, was tested using 30 days of school lunch data and 30 days of individual dietary records from middle school students. Results showed the system's recommended meals achieved significantly higher Chinese Children Dietary Index scores than actual or self-selected diets.

Use Cases

• Benchmarking AI meal planning algorithms based on the described ontology and genetic algorithm framework.
• Studying dietary imbalances in Chinese youth based on the food-group and nutrient adequacy metrics used in the pilot.
• Developing culturally adapted nutrition recommendation systems based on the integration of Chinese dietary guidelines and expert knowledge.

Strengths

• Includes results from a pilot validation study comparing system recommendations to actual school lunches and individual dietary records.
• The underlying system integrates multiple knowledge sources: dietary guidelines, expert knowledge, and food and meal data.
• Diet quality was assessed using multiple validated metrics: the Chinese Children Dietary Index (CCDI), nutrient adequacy rates, and food-group diversity.

Limitations

• The primary file is a DOCX document (672.2 KB); the underlying dataset of meal plans or food ontology is not directly available.
• Column-level documentation is absent; field semantics must be inferred from the study description.
• Row count is unknown, which may limit suitability assessment for large-scale model training.
