Abstract:
Integrating structural data across heterogeneous web repositories requires mapping schemas that use different naming conventions and hierarchical designs. This paper develops a holistic schema matching framework for XML documents that analyzes both element labels and contextual data structures. The system computes semantic similarity scores by mapping element terms onto WordNet taxonomies, while structural constraints are evaluated using a modified tree-edit distance algorithm. The framework was evaluated against a benchmark dataset of 50 enterprise XML schemas from the e-commerce sector. The proposed matcher achieved an overall precision rating of P = 89.2% and an F-measure score of 86.5%, outperforming baseline linguistic matchers by 14.8%. The runtime execution complexity was successfully restricted to O(N²) relative to tree node density. This reduction allows the system to discover complex data correspondences in large enterprise data warehouses without requiring extensive manual corrections.
