Under the circumstance of big data explosion, because the data is scattered, chaotic and unordered, it is very difficult for the effective and quick resolution of the user's problems by means of the existing information. This paper intends to formulate the solving process of complex problems, organize the knowledge needed, analyze the connection between problem, knowledge and solving process. Knowledge and the correlation is described between different knowledge with the aid of granularity principle. In order to resolve the problems of users, at first, static knowledge is organizated on the process of granularity, secondly, related dynamic knowledge is decomposed, knowledge granularity can be adjusted, the model is built on two-type knowledge granularity, the dynamic and the static knowledge organization are established, hence the user's problems is solved, the high efficiency knowledge service is provided for the user.
