1. Introduction
The typical approach to data integration is to start
by defining a common mediated schema for all the data
sources, then to match and map the data sources to this me-
diated schema. This assumes that the user (1) knows all the
sources that should be included in the data integration sys-
tem, and (2) knows all the concepts that are expressed in
these data sources (which will come together to form the
mediated schema). These assumptions do not necessarily
hold in cases where the data integration task involves hun-
dreds or thousands of data sources, especially if these data
sources are new to the user. Such "Internet-scale" data in-
tegration tasks are becoming increasingly more common,
arising in scenarios such as Web data integration, peer-to-
peer networks supporting structured queries, personal in-
