....supposed to be displayed next to or in a Web browser. In addition, the implementation should be completely Web based, requiring no client side installation. Special care has to be taken about scalability issues and ease of deployment. Existing tools such as SiteBrain [2] Tree Studio [3] WebToc [4] or Mapa [5] only focus on exploiting the site s inter page topology for visualization while usage and content data is rarely used. Besides focusing on a single form of visualization and data simplification, all applications tend to be proprietary and are not available cross plattform. In ....

....so that improvements can be made. Strategists would also like to mine information about users, such as product interest. Users need tools to navigate and locate information faster. To support these 55 sensemaking tasks, visualization of large hypertext spaces has been done by various researchers [5, 7, 27, 46, 109, 78, 69]. These systems are designed with a fixed priori with a limited set of tasks in mind. A system has yet to provide a set of primitives for conducting iterative and cyclic analysis tasks on Web ecologies. In our work, we provide such a system by handling very large Web sites (15,000 files) and ....

....Web pages. Ocelot synthesizes summaries, rather than extracting representative sentences from text. The system s final result is a static summary. Ocelot does not provide progressive disclosure where users can drill into parts of the summary, as we do in the Power Browser. Another system, WebToc [18], uses a hierarchical table of contents browser; that browser, however, covers entire sites, and does not drill into individual pages. Similar to our Partition Manager, the system described in[15] applies page partitioning to Web pages. The purpose of that system s partitioning efforts, however, ....

....Labels and lines connecting related items add further challenges for novice users. Tree structures are commonly presented as indented outlines that can be scrolled and opened or closed to expose or hide levels as in Microsoft s Windows Explorer, Allen s Dewey GUI (Allen, 1995a) or WebTOC (Nation et al. 1997). Trees represented as node link diagrams are useful, but as they grow to include thousands of nodes and many levels, layout and navigation problems become serious. Treemaps ensure a fixed size presentation, but are complex, and many users require 15 20 minutes of training (Johnson and ....

Nif T nav [11] provides a hierarchical navigator and shows the state of the navigation using a tree structure. Similarly, WebToc [14] visualizes the contents of a Web site with a hierarchical table of contents. Brusilovsky [4] describes Adaptive Navigation Support (ANS) methods for Web based systems, like link ordering. WebMap [7] creates a graphical map showing the navigation history. Cha cha [5] uses a pre computed tree ....

....to a restricted part of the graph and squeezing the rest into the remaining area. Fisheye lensing has been combined with zooming and applied to Web navigation in [3] Related non linear display methods for trees are hyperbolic maps [10] and perspective walls [12] Another approach used by WebToc [14] and Nif T Nav [9] is to display the site structure as a hierarchy, which can be navigated like a file system. With the HyperG system [1] a site author explicitly designs a hierarchy of nodes in addition to associative links. An advantage of this is, that both a hierarchy view and a local view of ....

....is also made available by Martin Dodge, at the University College of London. This cyber geography atlas includes a section dedicated to site maps. Because Web sites are generally organized hierarchically, a number of tools have been developed to represent hierarchical site maps, including WebToc [40], Nif T Nav [22] and MAPA [11] Moreover, visualizing the structure of a Web site relates to the general problem of visualizing large hierarchical and graph structures. Several approaches have tried to solve this problem by combining an overview of the structure with a smaller, but more detailed ....

....node provide minimal preview or overview information about the pages they represent. These constraints and limitations are probably why Starnine has chosen to eliminate LiveIndex from their product line. An example of the expanding outline technique combined with added overview features is WebTOC (Nation, 1997). Benjamin D. Brunk Animated Web Overviews 13 Figure 10: WebTOC overview of UMD s HCIL web site WebTOC is a Java applet that provides a table of contents using a frame similar to the SILS page shown earlier (SILS, 1998) This software was originally written to enable researchers to browse ....

....between items with a few subordinate links or many links. As an alternative, a bar representing the total number of items can be shown. The user has the option of viewing just the colored lines without the text descriptions. This more compact visual representation makes size comparisons easier (Nation, 1997). Such added information can be very useful for creating an overview of a web site. WebTOC does take up a large amount of screen space to the point of nearly crowding the actual page out of view at times. This problem could be mitigated by using JavaScript to pop up a separate browser window ....

....deliver information to users. Marketing strategists would also like to mine information about users, such as product interest. Users need tools to navigate and locate information faster. To support these tasks, various researchers have visualized hypertext spaces using various methods [10,16,12,1,19,2,14]. Each system is designed for specific tasks, and has enabled users to better understand Web spaces. Our targeted users include Web analysts, marketers, advertisers, Webmasters, and administrators, who have a need to reduce the cost of accessing millions of pieces of related usage information. We ....

....and Spence [9] were early demonstrations of the benefits of progressive visual querying. Other systems showed relevance of results: for example Veerasamy and Navathe [15] used histograms, and Hearst [7] used TileBars to visually present relevance of results to the terms used in the query. WebTOC [11] uses a hierarchical outliner and a bar chart presentation to preview the size and type of items (e.g. image, sound, etc. within each branch. Eick [4] proposes to augment sliders of visualization systems with density plots or bar charts. Antis, Eick, and Pyrce [2] introduce methods for ....

The Coolidge Collection is highlighted revealing its attributes and short description at the bottom of the screen WebTOC for browsing an individual collection. The individual collection browser tool is called WebTOC [Nation et al., 1997]. One difficulty webmasters and users alike have is representing the quantity of information and its distribution within a set of linked documents. Digital librarians must manage huge directories and need tools to visualize directory structures and data types. Knowledge of the quantity and types ....

....the collections was to be provided. A metadata format was defined by the LC team, and some data was generated for the collections used. The timeline, collection list and menus are created automatically from this metadata. The individual collection browser tool we developed is WebTOC (Figure 5) [11]. WebTOC generates a table of contents using two different strategies: following existing HTML links or using the underlying file system structure. Following links is appropriate for existing web sites, while using the file system is appropriate for newly digitized collections which have not yet ....
