A Practitioner's Guide To Taxonomies, Part I

Summary

A taxonomy is a low-fidelity semantic structure that provides significant returns on investment by establishing definitions, context, meaning, and inference through hierarchical relationships. It avoids the complexity and overhead associated with full ontological modeling. Taxonomies represent the third stage in the Ontology Pipeline® framework, yet organizations frequently attempt to build them first. Furthermore, many enterprises prematurely automate taxonomy creation without first establishing a controlled vocabulary, which often leads to significant issues.

Key takeaway

For data architects or knowledge managers planning semantic structure initiatives, prioritize establishing a controlled vocabulary before attempting to automate taxonomy creation. Rushing automation without this foundational step can introduce significant problems, undermining the potential benefits of a well-structured taxonomy.

Key insights

Taxonomies offer high ROI as low-fidelity semantic structures, enabling context and inference without full ontological complexity.

Principles

• Hierarchical relationships define taxonomies.
• Controlled vocabularies precede automation.

Topics

• Taxonomies
