Overview

Engineering, trade and management oriented activities rely on a wide variety of data sources all over the world and are performed by means of various computer-supported systems. Such activities require not only that local data may be processed, but also that global data might be searched, compared and understood by computers systems, and that their meaning descriptions be available in computer-interpretable representations. Therefore, formal representation, sharing and exchange of data meaning representations appears as a prerequisite to allow semantic integration of data.

Over the last decade a number of new approaches were proposed for data meaning representation and for semantic integration of data . These approaches have all in common to use computer-interpretable representations of data meaning. Representations may be ontology's, thesauri or domain model, and various description languages and logic have been used for description and for reasoning, but these approaches opened new perspectives on integration of heterogeneous data.

The purpose of this topical day is to bring together researchers, engineers, standard developers and practitioners interested in the advance and application of semantic integration of heterogeneous data to review and discuss some typical example of data integration projects.
