Abstract.
Schema matching is the problem of finding mappings between
different structured schemas. When retrieving information from
digital libraries with heterogeneous schemas, the query over a target
schema has to be transformed into a query over the schema of the digital
library (the source schema) it has been submitted to. Schema mappings
define the rules for this query transformation.
In this paper we address the issue of automatically learning these mappings;
furthermore, we evaluate their effectiveness in accessing distributed,
heterogeneous digital libraries.
