Furthermore, based on the segment markets theory in the Marketing model, to propose a User Interface (UI) classification strategy and formulate a set of hypermedia design principles for further UI strategy & e-learning resources in semantic web content. These research findings: (1) Irrespective of whether the simple declarative knowledge or the complex declarative knowledge model is used, the "CM + SS + KOD navigation system" has a better cognition effect than the "Non CM + SS + KOD navigation system". However, for the "No web design experience user", the navigation system does not have an obvious cognition effect. (2) The essential of classification in semantic web design: Different groups of user have a diversity of preference needs and different cognitive styles in the CM + SS + KOD navigation system.r.
