This paper presents a novel data model to organize the contents of web pages so that they can be dynamically adapted for heterogeneous terminal devices. Due to the constraints on the screen size and display resolution of handheld devices such as personal digital assistants and mobile phones, most existing web pages, which were initially designed for personal computers, are not suitable to be rendered directly on these devices. To enable conventional web pages to be dynamically adapted according to the types of the terminal devices, a data model named Content Container Tree (CCT) is proposed in this paper. The CCT data model manages the semantics and contents of a web page with an embedded-tree structure. By traversing the CCT tree, the user can find and locate a particular portion of the content of interest that is at a dimension comparable to the screen size of the terminal device. Based on the CCT data model, a multilevel-index navigational model is also proposed to enable the user to navigate through the CCT tree at different levels and retrieve the target content portions according to their semantics. The CCT web content adaptation approach is distinguished from other approaches in the following aspects: first, the CCT approach is data oriented rather than process oriented; second, the CCT approach supports multilevel granularity of the contents; finally, CCT approach is dynamic in that result pages can be generated on the fly by request.
