%X Classification is the basis of understanding, and information exploitation is a prerequisite for information use. The paper studies the partition ideology of extension set, analyses the classification properties of extension set (including the transferability, dynamic property, criticality and relativity of classification), which shows that the classification characteristics of extension set are key points for solving non compatible problems. And then we present the extension method of information exploitation, which is an effective means to obtain creative information.
