Knowledge Architecture Based on User Experience--A Review of the Basic Principles of KA in Web2.0

As an open complex adaptive knowledge system, Web2.0 uses some applications like Blog, Wiki, Tag, SNS, RSS as its kernel, and puts many complex new theories and technologies, for example, Six degrees separation, Synergetics, Long tail, XML, Ajax into the background. So that knowledge production, communication and utilization have realized in self-organization and ordering through users´ widely particip- ating under the restriction of simple rulers by the patterns of multiple, multiple, personalization and decentralization. The above make users become the adaptive agent of knowledge architecture (KA) in the Web2.0, revert KA to its original state of human-oriented and gives users abundant experiences, and made KA present the new characteristics of hierarchy, multiple and complexity. Therefore, the traditional KA theory can´t explain and serve the new character, so that it is necessary to reveal the basic principles and evolution mechanism of the personal KA, Website KA and social KA in Web2.0 by introducing some complex theory and methods such as self-organization theory, emergence theory, and loop feedback theory from a new perspective.
