The measure method of knowledge representation based on knowledge mesh is proposed to solve the selection of knowledge mesh in knowledge mesh base.Firstly,the definition of knowledge amount was given,and its properties and conclusions in knowledge mesh operation were proved in detail.Then,the measure method of knowledge representation was applied to the selection of knowledge mesh based on user＇s functional requirements.The similarity and knowledge amount based on user＇s functional requirements were used to quantitatively evaluate the knowledge mesh.Finally,the proposed method was exemplified, which shows the effectiveness and the feasibility of the method.
