Querying distributed data through distributed ontologies: a simple but scalable approach
François Goasdoué, M.-C. Rousset · IEEE Intelligent Systems · 2003
This framework for peer-to-peer data-sharing systems allows efficient query answering over a network of semantically related peers. A simple class-based language appropriate for practical applications defines peer schemas as hierarchies of atomic classes and mappings as inclusions of logical combinations of atomic classes.
