In the 1960s Professor Hu Guoding proposed a method of Boomerang measuring information based on the idea that connotation and denotation of a concept satisfies inverse ratio rule.According to this information measure, firstly we put forward the information quantity for information systems and decision systems; then, we discuss Catch the updating mechanism of information quantity for decision systems; finally, we give an attribute reduction algorithm for decision tables with dynamically varying attribute values.
