Abstract

According to the real situation that there exist a great deal of incomplete knowledge in Web database, IK-tableau model generation method based on the incomplete knowledge processing of tableau is presented. The model adopts the non-classical logical method, expresses the Web database information as logical formulae set and expands it by model generation operator. By using IK-tableau, incomplete knowledge in web database can be found out and be repaired to generate knowledge model. In the meantime, deep web searching can be further guided by using this model.
