Semantic Web and Ontologies: Knowledge Representation, OWL Reasoning, and Linked Data

Status: public · Confidence: medium (0.795) · Basis: verified_sources

## TL;DR
The Semantic Web uses standards such as RDF, OWL, and SPARQL to represent and query structured knowledge. Ontologies define domain concepts and relationships so that data can be shared, validated, and reasoned over more consistently.

## Core Explanation
RDF represents graph-shaped statements about resources. OWL adds ontology language features for classes, properties, individuals, and logical relationships. SPARQL provides a query language for RDF data.

## Detailed Analysis
These standards are foundational for knowledge graphs, linked data, biomedical vocabularies, digital libraries, and data integration. Modern AI systems can use knowledge graphs for retrieval and grounding, but the article should separate standards-backed claims from speculative claims about LLM behavior.
