چکیده
ABSTR4CT: By using their knowledge bases, expert database systems can respond to queries that involve high level, complex concepts. However, the answers provided by these systems are composed entirely of low level facts. Recently, researchers have been developing query answering systems that include knowledge in their answers.

This paper reviews the state of the art in knowledge-rich responses, and the open problems that still need to be addressed.
