Study Of Weakening Strategy For Contradictory Information In Contradictory Problem

With the rapid development of Information Technology, computer application field becomes more and more wide. Today, Computer Application is no longer just scientific computing, but more other areas, such as Computer Control, Information Management, CAD and so on. This requires the computer to become more intelligent, even can help people solve the contradictions independently.Human history is replete with problem-identifying and problem-solving. In the social development, people proposed a variety of methods to solve a variety of problems. Accuracy issues, random issues and fuzzy issues all have their own solving method. However, in addition to the three issues above, there is contradiction. Extenics uses formal model analyzing the possibility of development of things, so as to obtain the method of resolving contradictions. It has very important significance to improve human intelligence. Extension studies the contradictory by qualitative and quantitative method to obtain the way to resolve contradictions. Contradictory information is a formal description of Contradictions. It expresses the spear side, the shield side and contradiction degree.The contradictory information theoretical system of Contradictory information include classification of Contradictions, the definition, nature and formal model, measure of contradict. The systematic study on the Contradictory information is based on the Extension. The matter-element provides a formal description of Contradictory information; the extension set and correlation function provide metric system for Contradictory information; and extension transformation provide a series of methods for Weakening of contradictions.The main research direction of this paper is the weakening strategy of Contradictions. Firstly, this paper introduces the basic theory of extension:Basic element, extension set and correlation function. Then the basic theory of contradictory information, such as concept, classification, and extension transformation is introduced. On the basis of contradictions, then the contradiction information is described in terms of definition, extraction, classification, weakening and evaluation. Finally, a framework of weakening strategy is present and some examples of weakening strategy application are introduced.
