abstract = {Traditional query processing provides exact answers to queries. It usually requires that users fully understand the database structure and content to issue a query. Due to the complexity of the database applications, so called locally non-reachable queries can be posed which traditional query answering systems can not handle. In this paper a query rough-answering system for a multi-agent system is presented to rectify these problems.},
