abstract = {We introduce constructive neighborhood systems to define a notion of soft information granulation. We also discuss several strategies for reduction of information encoded in decision tables of these systems. These strategies are used to reduce in a decision table of a given neighborhood system the number  of objects, attributes,   decision  values,   conditional value attributes or are used to search for more relevant conditional attributes.  All these methods are expected to produce better  approximation of decision algorithm corresponding to  a  given decision table.},
