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, incorrect or incompletely specified queries are frequently posed and the user often receive no answers or they might need more information than they have received. In this paper a multi-agent system called a cooperative knowledge-based system (CKBS) is presented to rectify these problems.},
