Conecpts to improve the visualization of implicit node and link types on the Web.
Current Web browsers make it hard to predict what will happen if a link is being followed: users get other information than they expect, a new window may be opened, a download starts, or the destination object is just not available. Instead of giving an appropriate notifi-cation in advance, users have to follow a link, check if the document contains the expected information, get back, try another link etc. However, usually it is possible to obtain additional hyperlink information from several sources like link anchor tags, the user's history and web servers. Furthermore with little enhancements Web servers may include even more additional information to the hyperlinks in Web documents. These can be displayed before users select a link to improve navigation and reduce the cognitive overhead.
