Foundations of Knowledge Representation
Module Overview: Foundations of Knowledge Representation
In modern enterprise architecture and AI systems, knowledge representation forms the backbone of interpretable, machine-actionable data. Moving beyond unstructured documents and relational silos requires establishing formal semantic models that encode not just terms, but the logical relationships and constraints that govern a business domain. This module establishes the foundational principles of semantic networks, bridging the gap between lightweight classification systems and fully expressive, computable ontologies.
Throughout this module and its accompanying topics, you will examine the progression from informal taxonomies and controlled vocabularies to formal Description Logic frameworks. You will explore how the W3C Semantic Web Stack organizes URIs, RDF statements, and schema definitions into an interoperable foundation for enterprise graph architectures and agentic context engineering.
Learning Objectives
By completing the topics in this foundational module, you will be prepared to:
- Distinguish Semantic Expressivity: Contrast the operational boundaries of folksonomies, SKOS taxonomies, and OWL ontologies to select the appropriate modeling paradigm for your domain.
- Navigate the Semantic Web Stack: Trace data representation from basic graph triples (Subject-Predicate-Object) through schema definitions to constraint enforcement layers.
- Avoid Common Inheritance Traps: Recognize architectural anti-patterns when converting legacy hierarchical trees into formal subclass hierarchies.
