Primitive interface structures in browsing the Web

Browsing WWW documents is interactive. Not only their layout but also their interaction structures should be organised well in order to be effective to the reader and to get engineering benefits by composition. We define four primitive logical browsing structures. These are the sequential, go-to, nested and iterative structures. To support these primitive browsing structures, five groups of interface structures are proposed in this paper. These are the sequential, go-to, nested, loop and evolutionary interface structures.
