Schema matching and mapping: from usage to evaluation

Angela Bonifati, Yannis Velegrakis

Abstract: This tutorial provides an overview of current evaluation techniques for schema matching and mapping tasks and tools, alongside existing and broadly used evaluation scenarios. The objective is to introduce the audience into the area of matching and mapping system evaluation, and to highlight the need for leveraging robust benchmarks and yardsticks for the comparison of the different matching and mapping tasks. Open research problems will be identified and presented. The tutorial is for both experienced researchers and unfamiliar investigators looking for a quick and complete introduction to the topic.
