Project SummarySiteMap is a Java application that visualizes a given Web site or a collection of links. Through a Web robot, "SiteMap first traverses every link of the Web site, collects statistical data, and indexes all the words and pages of the site. Based on the statistical data and the indexing, SiteMap converts each page of the site into a vector, and uses these vectors to train a neural network. As the outcome, the trained neural network presents the site in an organized map: subject areas are identified and labeled; their sizes and locations are determined by relationships among the subjects and by their occurrence and co-occurrence frequencies. Links are clustered and located within their respective subject areas, represented by colored dots."
"To help users interact with the [resulting] map, SiteMap provides various interactive tools. For example, areas can be labeled in more/less details through adjusting a scroll bar; links can be selected through clicking or dragging; contents of any selected links can be shown in a separate window, etc."
A Java-enabled browser is required to view the sample SiteMaps.

Project Summary...[T]he objective of the LyberWorld research project ... [is] to develop novel, intuitively usable visual user interfaces, which significantly reduce the cognitive load of the user when working with database and information retrieval systems."
"In an experimental application prototype, the probabilistic information retrieval system INQUERY has been enhanced with such an interface. The resulting visual information system is currently running with several full-text databases. CORDIS publication database contains 800 ... abstracts of scientific publications and project descriptions of European research projects."
"The visualization user interface is designed on the basis of several agent based tools for the three-dimensional graphical visualizations of the retrieved/stored information structures and the information dialogue itself. It provides users with intuitive control over their present search state, relevance of retrieved information items and potential further steps at any stage of the visual information dialogue. Therefore users are continuously in control of their 'positions' in the searched information 'space'."
"For reaching this goal the content space of the database/the retrieval session has to be visualized. This is done by means of Search Trees, Relevance Speres and Terminology Surfaces. The content space of a visualized fulltext database contains term items and document items. They can easily be distinguished because of their different colours (blue and red respectively). By maneuvring through the visualized content relations, users can search through all potentially relevant text documents without having to read them completely or to contrive search terms of their own. After gathering all potentially interesting documents in the Search Tree, the Relevance Sphere visualization is used to visually cluster information spaces and to determine the set of most relevant documents, i.e. the result kernel of the search."
The LyberWorld INQUERY based "retrieval mechanism will be updated with an integrated HTML parsing functionalty to enable the prototype to become a complete visual Webreader."
The relevance sphere and the spiral tree have been ported from SGI-only versions to Windows 95 and Windows NT environments. These are currently being converted into an Active-X-Control that will support VRML export and plans call for this functionality to be available in Fall 1998.

Project NameSPIRE(tm) (Spatial Paradigm for Information Retrieval and Exploration)
Principal InvestigatorJames J. Thomas (firstname.lastname@example.org)
Project SummarySPIRE" allows users to explore complex relationships between text documents. A collection of visual and interaction tools, SPIRE graphically displays images based on word similarities and themes in text. No prior knowledge of the information or selection of themes or topics is required. SPIRE creates its visualizations by processing these similarities into the key topic and themes and organizing the data into visual representations that allow the user to explore and discover relationships between text documents."
"Two technologies within SPIRE, Galaxies and Themescape, provide natural visual metaphors requiring little training to use. Galaxies computes word similarities and patterns in documents and then displays the documents on a computer screen to look like a universe of "docustars." Closely related documents will cluster together in a tight group while unrelated documents will be separated by large spaces. In Themescape, themes within the document spaces appear on the computer screen as a relief map of natural terrain. The mountains in Themescape indicate where themes are dominant; valleys indicate weak themes. Their shapes--a broad butte or high pinnacle--reflect how the thematic information is distributed and related across documents. Themes close in content will be close visually based on the many relationships within the text spaces."

Project Summary"fsn (pronounced 'fusion') is a file system navigator in cyberspace. It lays out the directorys in a hierarchy with each directory represented by a pedestal. The height of the pedestal is proportional to the size of the files in the directory. The directories are connected by wires, on which it is possible to travel. On top of each directory are boxes representing individual files. The height of the box represents the size of the file, while the color represents the age".
"fsn is intended as an investigation in information landscape navigation. Although the file system was chosen as a system to navigate through, similar paradigms could be applied to other trees and graphs, such as call graphs."
"fsn is a prototype and an experiment. It is neither a full featured product nor a replacmeent for [other] file system manager[s]...".

Principal InvestigatorSerge Rezzonico (firstname.lastname@example.org)
Project SummaryBED (Bookmarks Exploring Dabbler) is a prototype 3D bookmarks generator using VRML. The "generator reads a Netcape bookmarks file, parses it and generates a VRML file. A VRML browser can be used to visualize the scene and navigate through it."
"The 3D generator works best on bookmarks organized with menus, as opposed to the case where one has a long flat list of URLs. ... Submenus are also supported, with the limitation that starting from the third level of submenus they are all considered at the same level. It is advisable not to have one single submenu with many other submenus in it; instead, it is better to have different submenus directly in the main menu."

Project SummaryNarcissus uses ... "self-organising systems and virtual reality to generate visualisations through which users can navigate and manipulate objects in the visualisation. The system is implemented as a process which communicates with applications (e.g. Web browsers and programming environments) using KQML," and provides a degree of application independence which permits it to work concurrently with several, possibily heterogeneous applications, facilitating collaborative work among users.
"The current model is loosely based upon physical systems with rules defining forces that act between the objects. These forces cause the objects to move in space." In the running model, objects migrate through space so that they are spatially close to other objects with which they are semantically related.
"The user can determine which relationships are active within the model and hence which relationships will be responsible for generating attractive forces between objects," and can also select individual objects and classes of objects which should be visible. The system can draw arcs to indicate relationships between objects and label objects with their attributes (e.g. URL).

Project NameInternet Foyer
Principal InvestigatorsSteven D. Benford (email@example.com)
Project Summary"The Internet Foyer is an example of a mixed reality - an electronic meeting space which spans the physical and virtual worlds. The Internet Foyer involves the use of Collaborative Virtual Environment technology to create a navigable and populated 3-D visualisation of an organisation's WWW home pages."
"Using collaborative virtual reality software, people can enter a specific Internet Foyer from anywhere over the Internet. Once inside, they can navigate the 3-D visualisation, selecting pages of interest. They are also made aware of the presence of other VR users and are able to communicate with them using live audio links in much the same way as they would be if they encountered them in a normal foyer in a physical buidling. In addition, they are made aware of the presence of users of more traditional 2-D (i.e. dimensionally challenged) WWW browsers who happen to be wandering over these particular WWW pages at the time."
"To complete the Internet Foyer, this visualisation is then projected onto the wall of a physical foyer in a real building while, simultaneously, a real-time video image from the physcial foyer is texture mapped back into the visualisation. This allows visitors to the virtual and physical foyers to communicate with one another."

Project SummaryVR-VIBE extends the VIBE approach [developed by Robert R. Korfhage and students and colleagues at the University of Pittsburgh] into three dimensions and creates visualizations of bibliographies. Users specify keywords that they wish to use to generate the visualization and place these keywords in 3D-space. Representations of the documents are then displayed in the space according to how relevant each document is to each of the keywords ... . The position of a document depends on the relative importance of each of the keywords to it; thus a document equally spaced between two keywords is equally relevant to both, while a document close to a particular keyword is relevant to that keyword only. Absolute relevance is depicted by the colour of the documents representation, the more relevance the document, the brighter the colour - this is necessary to distinguish between documents that are equally only slightly relevant from documents which are highly relevant but are placed in the position because the proportion of their relevance to each keyword is the same."
"VR-VIBE is a a virtual reality application ... intended to support the co-operative browsing and filtering of large document stores."

WWW3D is "a novel browser that provides a single 3D display which integrates the display of the Web documents themselves, the structure of the part of the web that the user has browsed and history information showing the links the user has followed in the recent past."
"WWW3D uses the information contained in HTML tags to produce a representation of the document in 3D space. A web document is represented as a sphere which is labelled with the document's title. The contents of the document is placed around the inside surface of the sphere. Displaying large amounts of text in a satisfactory way is difficult in current VR systems so textual information is currently represented by icons that can be unfolded to reveal the entire text. The first few words of the piece of text are displayed under the icon to give some indication of the contents. Images are displayed by texture mapping them onto polygons on the inside surface of the sphere. Finally, links to other documents are represented as icons labelled with their destination."
"To reduce the visual complexity of the virtual environment WWW3D makes extensive use of Level of Detail(LOD) operations. When viewed from outside a document is represented as an opaque sphere and the actual document contents is not displayed. When a user enter's a document to view it the sphere is drawn in wireframe so that the rest of the virtual environment is still visible". "WWW3D is implemented in DIVE and supports multiple concurrent users who are visible to each other and who may either be browsing the the same or different sets of Web documents."

The system also provides mechanisms to integrate query formulation across the visual representations."
"The Document Explorer employs context extraction, visualization, and interaction tools to supply a 3D interface to text-based semantic structures. The goals of the system have centered on providing user-manipulable visualization structures and facile 3D interaction techniques for use in the highly interactive process of information seeking. The figure above shows a screen display of a structure formed from document relationships."

Product Summary"Current Web servers and browsers focus attention at the link and page levels. These levels are too low to represent gracefully some higher-level structures, resulting in many more entities in the Web space than are necessary and hence to orientation and sensemaking problems." WebBook(tm), is a "3D interactive book of HTML pages. The WebBook(tm) allows rapid interaction with objects at a higher level of aggregation than pages." Web Forager(tm) is "an application that embeds the WebBook(tm) and other objects in a hierarchical 3D workspace.
"Given a collection of web pages, it preloads those pages and displays them as a collection using an augmented simulation of a physical book. 3D graphics and interactive animation are used to give the user a clear indication of the relationship between the pages of the book. Each page of the WebBook(tm) is a page from the Web. Links are color coded so the user can easily tell the difference between a reference to another page in the book (red links) and a reference outside the book (blue links). Picking a red link will animate the flipping of pages to the desired page. Picking a blue link will close the current WebBook(tm) and look for the page elsewhere. If the page is in another WebBook(tm) stored on a bookshelf, that WebBook(tm) is opened to the desired page."
"The WebBook(tm) provides a representation of a more aggregate Web entity above the page and allows rapid local interaction with it. The Web Forager(tm) allows interaction with multiples of such entities and allows for the necessary tradeoffs among fast access, number of entities, and screen space."

Product SummaryYahoo! 3D is Yahoo's VRML-based virtual world. Yahoo! 3D allows one to explore more than a dozen main Yahoo! categories, or 'worlds' in three-dimensional space, interacting with objects rather than text, using three-dimensional space to organize these various subject groups.
Note: Worlds vary in size 100K to 200K, and all are compressed. It is best to use Yahoo! 3D with an ISDN level connection, or higher. Each world is compressed and needs to be decompressed by the browser. Users with modems will experience significant download times. Navigation through the worlds may be sluggish on slower processors with low memory availability.
Yahoo 3D! includes over 450 objects within its current. collection. Arts, Education, Government, Health, News, Recreation and Sports, and Science, are among the major Yahoo categories represented. Several pre-defined options are active, most notably 'Walk', 'Spin', 'Look', and 'Slide' for navigating Yahoo! 3D.
Yahoo! 3D requires browser support for Live3D and uses the VRML modeling tool developed by Caligari Corporation.
