  ABSTRACT={We report on our experience in developing a query-answering system that
     integrates multiple knowledge sources. The system is based on a novel architecture
     for combining knowledge sources in which the sources can produce new subgoals
     as well as ground facts in the search for answers to existing subgoals. The
     system uses a query planner that takes into account different query-processing
     capabilities of individual sources and augments them gracefully. A reusable
     ontology provides a mediated schema that serves as the basis for integration.
     We have evaluated the system on a suite of test queries in a realistic application
     to verify the practicality of our approach.}
