Abstract: There is no uniform solution to knowledge management though various kinds of methods have been proposed. This paper introduced a sort of general structural modeling method of service industry drawing on the experience of Dublin Core Metadata Elements with a thought of hierarchy, for modeling knowledge of service industry. In order to describe the model clearly, Dynamic Description Logic(DDI)was used to model actions and state changes in the model,which can make knowledge description and management more rigorously.
