Abstract

Data integration is an extremely complex process, especially one involving big data sources. For this reason, several high-level approaches have been proposed to master the inherent complexity of this process. These exploit either natural language processing, or ontologies to perform the data integration process at requirement level, or visual languages with icon operators capable of specifying reconciliation operations on data source conceptual schemas, like for example the visual language CoDIL (Conceptual Data Integration Language) that we have recently proposed. In order to provide automated support to suggest the CoDIL icon operators that can be applied, in this paper we propose a Description Logic-based schema matcher, which extends current at- tribute matching approaches to more complex constructs of conceptual schemas. We also sketch a possible evolution of the system architecture for the tool CoDIT (Conceptual Data Integration Tool), supporting the data integration process based on CoDIL.
