ns3:abstract "Sometimes one does not want all the solutions to a query but instead only\nthose that are most desirable according to user-specified preferences. If a\nuser-specified preference relation is acyclic then its specification and\nmeaning are straightforward. In many settings, however, it is valuable to\nsupport preference relations that are not acyclic. We discuss a definition\nof desired solutions for arbitrary preference relations and show its\ndesirable properties. We modify a previous extension to SPARQL to correctly\nhandle any preference relation. We also propose an additional extension\nthat returns solutions at multiple levels of desirability.\n" .
