碩士 === 元智大學 === 資訊工程學系 === 95 === Web catalog integration has been addressed as an important issue in current digital content management. Past studies have shown that exploiting a flattened structure with auxiliary information extracted from the source catalog can improve the integration results. Although earlier studies have also shown that exploiting a hierarchical structure in classification may bring better advantages, the effectiveness has not been studied in catalog integration. In this thesis, we propose an enhanced catalog integration (ECI) approach extracting the conceptual relationships from the hierarchical Web thesaurus to improve the accuracy performance. We have conducted experiments with real-world catalogs in a flatten format and in a hierarchical format. The results show that the ECI scheme effectively boosts the integration accuracy of both the flattened scheme and the hierarchical scheme with the Support Vector Machine (SVM) classifiers.
