Abstract: Today's business domains are increasingly struggling with meaningful data exchange between heterogeneous XML-based systems where syntactic interoperability does not overcome intrinsic semantic mismatches. The use of XML schemas has introduced exponential map complexity, with companies dealing with hundreds of variant data formats that defy unification in spite of common conceptual roots. Vocabulary heterogeneity is a key obstacle, with the same business ideas having different terminological representations across organizational boundaries, and polysemous words adding further disambiguation demands that cannot be handled by conventional XML processing. Structural differences add to semantic issues, in which the same information appears through varying nesting forms and organization patterns that serve different design ideologies and operational needs. Mediator-based ontological frameworks bring profound development in terms of automated generation of local ontologies from XML sources and construction of global semantic models that act as integration hubs. Modern implementations show considerable performance gains with logic-based matching algorithms handling large-scale alignment problems with hundreds of thousands of concepts while keeping precision levels beyond expectation. WordNet-assisted similarity measures offer advanced semantic evaluation capability through the exploitation of hypernymy relations, taxonomic relations, and synset organizations that allow precise concept mapping irrespective of differences in vocabulary. Experimental testing across standardized benchmarks shows consistent performance gains over conventional string-based approaches, with correlation coefficients showing strong agreement with human similarity judgments across varying conceptual domains.
