Table 1_Ontology-based dietary recommendation system for Chinese children and adolescents:

An ontology-based dietary recommendation system developed for Chinese children and adolescents. The system was evaluated using 30 days of school lunch data from a primary school and 30 days of dietary records from 30 middle school students. The dataset, authored by Zhiyu Zhang and last updated in May 2026, contains the study document describing the system's development and validation results.

Use Cases

• Benchmarking dietary recommendation algorithms based on the described ontology and genetic algorithm framework.
• Studying dietary imbalances in Chinese youth based on the Chinese Children Dietary Index (CCDI) metrics reported.
• Developing culturally adapted meal planning tools based on the integration of Chinese dietary guidelines and food data.

Strengths

• System performance is quantitatively validated, showing significantly higher CCDI scores for recommended meals versus actual meals (e.g., 117.39 vs. 103.41 in group experiment).
• The methodology is clearly described, involving a multi-criteria decision framework, a genetic algorithm, and pilot evaluations at group and individual levels.
• Dataset is openly shared under a CC-BY-4.0 license, facilitating reuse.

Limitations

• The primary file is a 671.2 KB DOCX document; the underlying structured data (e.g., the ontology, meal plans) is not directly available as a dataset.
• Row count and column-level documentation are absent; data semantics must be inferred from the study text.
• The pilot validation scale is limited to two school settings with 30 days of data each.
