How To Model Taxonomy, To Thesaurus, To Ontology, To Knowledge Graph

TLDR Evolving a taxonomy to a Knowledge Graph involves building hierarchy and metadata, understanding universal containers, and progressing based on entity specificity. It's important to start with universal categories for ontology, differentiate between classes and instances, and add unique relationships. In the knowledge graph stage, refinement may be needed, careful consideration of inferred hidden relations and exceptions is necessary, and identifying dense clusters, gaps, and bottlenecks in the data is valuable.

Key Insights

Start with Universal Categories in Ontology Creation

When creating an ontology, it's crucial to begin with universal categories and gradually refine the taxonomy to determine the lowest level of universal data needed for the specific use case. This initial step lays the foundation for a comprehensive and well-organized ontology, ensuring that it accurately represents the diversity of entities involved. It involves differentiating between classes and instances, and making explicit broader and narrower relationships to establish a solid structure for the ontology.

Carefully Populate Instance Data in Knowledge Graph

In the knowledge graph stage, instance data from the developed taxonomy and thesaurus can be populated. However, it's essential to be prepared for potential refinement as exceptions to the established rules may arise. This stage involves identifying and addressing inferred hidden relations, exceptions, and considering the overall shape of the knowledge graph to prevent the accumulation of orphan nodes and technical debt.

Identify Dense Clusters and Gaps in Data

The conversation emphasized the importance of leveraging the parts node from the taxonomy for machine learning and attribute identification. It also underscored the value of identifying dense clusters, gaps, and bottlenecks within the data, particularly in the context of the supply chain domain. This proactive approach enables organizations to optimize their data structures and enhance the effectiveness of their knowledge graphs.
