ABSTRACT:
A method and system are disclosed for evaluating imprecise database queries. At the time the imprecise query is executed, a membership function, representing the imprecise criteria of the query, is applied to entries of the databases. Data items are then accordingly identified depending on the results obtained from applying the membership function to entries of the database.
