In this paper, we present the preliminary results of the ongoing research activity we are carrying out in the context of approximate XML query answering when the schemas of the XML documents are available. The method we propose involves a preliminary schema matching process, which automatically identifies the semantic and structural similarities between the schema elements to be used in the subsequent operation of query rewriting, in which a query written on a source schema is automatically rewritten in order to be compatible with the other useful XML documents. The proposed approach has been implemented in a web service, named XML S3MART, which is part of the open architecture proposed in the ongoing Italian CNR co-funded ECD Project.

Abstract
In this paper, we present the preliminary results of the ongoing research activity we are carrying out in the context of approximate XML query answering when the schemas of the XML documents are available. The method we propose involves a preliminary schema matching process, which automatically identifies the semantic and structural similarities between the schema elements to be used in the subsequent operation of query rewriting, in which a query written on a source schema is automatically rewritten in order to be compatible with the other useful XML documents. The proposed approach has been implemented in a web service, named XML S3MART, which is part of the open architecture proposed in the ongoing Italian CNR co-funded ECD Project.
