Abstract
The typical approach to data integration is to start by
defining a common mediated schema, and then to map the
data sources being integrated to this schema. In Internet-
scale data integration tasks, where there may be hundreds
or thousands of data sources providing data of relevance to
a particular domain, a better approach is to allow the user
to discover the mediated schema and the set of sources to
use through an iterative exploration of the space of possible
schemas and sources. In this paper, we present ÁBE, a data
integration tool that helps in this iterative exploratory pro-
cess by automatically choosing the data sources to include
in a data integration system and defining a mediated schema
on these sources. The data integration system desired by
the user may depend on several subjective and objective
