Knowledge Structuring and Evaluation Based on Grey Theory

摘要

It is important nowadays to provide guidance for individuals or organizations to improve their knowledge according to their objectives, especially in the case of incomplete cognition. Based on grey system theory, a knowledge architecture which consists of grey elements including knowledge fields and knowledge units is built. The method to calculate the weightiness of each knowledge unit, with regard to the user's objectives, is detailed. The knowledge possessed by the user is also evaluated with grey clustering method by whitenization weight function.
