FoodKG

FoodKG enriches knowledge graphs in the Food, Energy, and Water (FEW) domains by adding semantically related triples, relations, and images to improve decision-making and knowledge discovery.

Key Features:

• Knowledge Graph Enrichment: Enriches input knowledge graphs constructed from raw FEW datasets with semantically related triples, relations, and images.
• Graph Embedding: Uses a graph embedding technique trained on AGROVOC, the controlled vocabulary published by the Food and Agriculture Organization of the United Nations, to provide semantic context for terms and classes.
• Semantic Similarity Scoring: Computes semantic similarity scores to quantify relatedness between entities and classes.
• Relation Inference and Classification: Establishes relations between different classes within FEW datasets and refines classification of existing entities using inferred relations.
• Evaluation: Compared performance against state-of-the-art word embedding and knowledge graph embedding models trained on the same dataset using the Spearman Correlation Coefficient, reporting superior correlation.

Scientific Applications:

• Decision Support: Supports decision-making in FEW domains by revealing semantic relationships across heterogeneous datasets.
• Knowledge Discovery: Improves knowledge discovery by adding semantically related triples and scored relations for FEW concepts.
• Data Integration: Enables integration of heterogeneous FEW datasets into semantically coherent knowledge graphs.
• Semantic Annotation and Classification: Facilitates precise classification and the use of scientific terminology for entities and classes within FEW datasets.

Methodology:

Enriches input knowledge graphs with semantically related triples, relations, and images grounded in original dataset terms and classes; employs a graph embedding technique trained on AGROVOC; computes semantic similarity scores and establishes inter-class relations; evaluated against word embedding and knowledge graph embedding models using the Spearman Correlation Coefficient.
