Abstract: The Semantic Web paradigm transforms unstructured web data into machine-readable knowledge frameworks to allow intelligent agent interoperability. This review paper provides a structured evaluation of state-of-the-art knowledge representation languages and ontologies developed over the past decade, including RDF, RDFS, and OWL2 profiles. We analyze their underlying description logics, expressiveness boundaries, and computational complexities during reasoning tasks. The paper details the practical limitations of current reasoners like Pellet and HermiT when executing large-scale web graphs containing over 100,000 assertions. Key architectural challenges regarding ontology alignment, semantic mapping, and schema reconciliation within decentralized federated databases are thoroughly categorized. Finally, we highlight emerging trends, such as the convergence of deep learning models with structural symbolic knowledge bases to improve natural language understanding. This synthesis provides developers and researchers with a clear roadmap for selecting optimal ontological frameworks based on scale and reasoning constraints.
