Berners-Lee, Hendler, and Lassila’s seminal articulation of the Semantic Web proposes not a replacement of the World Wide Web, but its epistemic augmentation through machine-readable meaning. Their central claim is that the Web must evolve from a document system optimised for human interpretation into a semantically structured environment in which computational agents can process, infer, and act upon meaning with minimal human intervention. This transformation depends upon a layered architecture of XML, RDF, and ontologies, each furnishing progressively richer semantic expressivity. XML supplies structural syntax, RDF encodes relationships through subject–predicate–object triples, and ontologies formalise conceptual relations and inferential rules, thereby enabling distributed systems to recognise equivalence, infer new knowledge, and coordinate across heterogeneous datasets. The article’s emblematic scenario—software agents autonomously arranging medical appointments through distributed reasoning—illustrates a vision in which intelligent agents do not merely retrieve information but orchestrate complex service chains through semantic interoperability. Crucially, this model rejects centralised knowledge control in favour of decentralised, URI-based semantic identification, preserving the Web’s heterogeneity while enabling logical coordination. The article’s theoretical significance lies in its synthesis of knowledge representation, automated reasoning, and distributed computation into a universal semantic infrastructure where meaning becomes computationally actionable. More than a technical proposal, the Semantic Web is framed as an epistemological reorganisation of digital knowledge itself: a system in which machine-readable semantics enable not only more precise search and automation, but the gradual convergence of disparate conceptual systems into a shared, extensible architecture of intelligibility. In this formulation, the Semantic Web emerges as both infrastructural protocol and cognitive paradigm for the next stage of networked knowledge.
