Using imprecise analogical reasoning to refine the query answers for heterogeneous multidatabase systems in virtual enterprises

Virtual enterprise is typically one kind of information-based enterprise. The features of information system in virtual enterprise can be generalized as heterogeneous and distributed. Its organization and production management put an essential requirement on information integration. A core problem in the integration of heterogeneous information sources is the resolution of a great deal of conflicts, which result in the situation of imprecise information. Therefore, it is necessary for the production activities of virtual enterprise to acquire the more informative information from the information source with imprecision based on database systems.
