Providing Interactive Site Maps for Web Navigation

One-dimensional linear navigation method is commonly used in current Web browsers. That is, a Web page may include some highlighted text strings that are linked to other Web pages. This kind of navigation from one page to another page lacks the whole structure overview required for relationships between Web pages. This paper presents how to use tree structure diagram s, a 2-dimentional view, as site maps for Web navigation. According to the user ’s focus in the process of Web navigation, a tree diagram is formed as a site map for each Web page dynamically. The user can interact with the tree-based sitemap to navigate to another site map or looking at a detailed view (i.e. a Web page) for a node in the tree diagram. The user can also adjust the diagr am for getting a preferred tree diagram layout if the user does not like the default layout form.
