Web catalog integration has become an integral aspect of current digital content management for Internet and e-commerce environments. The Web catalog integration problem concerns integration of documents in a source catalog into a destination catalog. Many investigations have focused on flattened (one-dimensional) catalogs, but few works address hierarchical Web catalog catalog integration (EHCI) approach based on the conceptual thesauri extracted from the source catalog and the destination catalog to improve performance. Experiments involving real-world catalog integration are performed to measure the performance of the improved hierarchical catalog integration scheme. Experimental results demonstrate that the
EHCI approach consistently improves the average accuracy performance of each hierarchical category.
