Ontology-Based Deep Web Data Interface Schemas Integration Method

Ontology-Based Deep Web Interface Schema Integration (OBDIS) uses two levels structure to establish matching relationships and eliminate semantic heterogeneity among concepts and terms of Database schemas on the Web, coupled with the assistance from domain ontology and form ontologies, in which the former is used to describe the domain knowledge and provide the sharing vocabulary base, and the latter is used to describe the semantic information of local data sources. The semantic and structure heterogeneity problem arising during the integration process of Deep Web data interface integration can be properly solved through creating the mappings between form ontologies and domain ontology, and the mappings between form ontology and local data sources. This paper not only focuses on the system implementation and main functions of OBDIS, but also promotes the efficiency and precision of the integration.
