The paper mainly take the pathology case expression based on semantic network as a foundation, and discuss the detail to the uncertainty within pathologic case and the match based on semantic network within the case base.The uncertainty of knowledge expression is a popular subject in expert system. The solution of the question in the specific domain not only relies on the specific domain determination knowledge, but also relies on expert's experience and the general knowledge. The uncertainty of objective things or phenomenon in the world has caused uncertainly performance on information and knowledge in people's each understanding domain. The phenomenon requests that expert system can reflect the uncertainty through knowledge expression and processing pattern. The paper discussed firstly the uncertainty concept and discussed the expression about the uncertainty within semantic network, finally established processing method on the uncertainty within the pathologic case base based on semantic network.While they diagnosis those massive similar diseases, doctors also accumulated many pathology cases. In these cases, which case can provide reference to other people's diagnose. The concept of the similarity is included in this question. I used the method of CBR and established the related mathematical model to solve this problem based on semantic network.I hope that the diagnosis error will be reduced through the research and the paper can help the peoples in research on the method to diagnose based on semantic network too.
