The organizational element
In this approach, the content elements of the document are organized by using hierarchical and parallel nodes and links. This organization will determine whether the document should be read sequentially or non-sequentially. The relationship determination of nodes is important in this step. The organizational element should determine how the nodes and links arranged to let user read sequentially or non-sequentially. An external and incoming links should be determined too. However, to explore information in scientific writing, a reader may read non-linearly. Thus, the organizational element has to be equipped with explore links. When there is an incoming link that leads to result node and its sub nodes then the reader can jump to another nodes non-linearly.
The presentation element
Three presentation types that have been identified for document writing:
1. Textual type that limited to the word or alphabetical content nodes such as title, definition, keyword, quotation, caption label, reference list, index, table of content, a paragraph, and appendixes.
2. Graphical type that presents the content and structure of document graphically such as document map, outline (like TOC), diagram, table, chart, picture, and icon.
3. Combined type is to present content and organizational element more comprehensively. For example, icon Goto in taskbar can lead to certain definition instead of clicking an associated word.
