A Bottom-Up Approach for Integration of XML Sources
Overview XML raises as the standard for semistructured data representation and data exchange in the Web. In this context, data integration mechanisms are required to provide an unified view of semantically related information of a same domain. In this paper, a bottom-up integration process is proposed to solve such problem. In this approach, an ontology is generated from the semantic integration of conceptual schemata derived from DTDs. The process is semi-automatic taking into account the intervention of a human expert to provide semantic adjustments. The resulting ontology is an unified vocabulary for semistructured concepts presented in several XML sources; keeps mapping information to DTD elements and attributes; and acts as a global schema for user queries.
