Abstract

In heterogeneous semantic peer-to-peer systems, peers describe their resources through ontologies that they can adapt to their particular needs. In order to interoperate, queries need to be transformed with respect to alignments between their ontologies before being evaluated. Alignments are thus critical for sharing resources in such systems. The authors report an experiment that explores how such alignments can be obtained in a natural way. In particular, asking users to provide alignments is a heavy constraint that must be relaxed as much as possible. This can be attempted through automatic matching. However, the authors suggest other possible solutions.
