An application of an information system via modern topology

This paper will discuss developing a new mathematical method through analysis of information system where we deal with some ambiguity problems. we will represent this knowledge into one or more types of classes then we can use these classes to make a topology called modern topology. after that we will compare the base of modern topology with other basis after removing some attributes then we will decide the core elements via the comparison. these elements will obviously be the true elements in the fact.
