LyberWorld is a prototype IR user interface. It implements visualizations of an abstract information spacefulltext. The presentation demonstrates a visual user interface for the probabilistic fulltext retrieval system INQUERY. Visualizations are used to communicate information search and browsing activities in a natural way by applying metaphors of spatial navigation in abstract information spaces. Visualization tools for exploring information spaces and judging relevance of information items

The presence of a spatial model in the user's mind and interaction with a system's corresponding display methods is regarded as an essential contribution towards natural interaction and reduction of cognitive costs during, e.g., query construction, orientation within the database content, relevance judgement and orientation within the retrieval context. WHY VISUAL TEXT RETRIEVAL ? Graphical user interfaces are nowadays state of the art within modern information retrieval computer systems. The basic metaphors for such interfaces are in most cases desktop or others derived from real world objects (e.g. library [11] ). Besides these, several visualization methods for abstract information structures have been developed (e.g. [9]). However, many text retrieval user interface components like query construction and result presentation are still form-or command-based. Looking at work in the area of Scientific Visualization, highly interactive graphical user interfaces (e.g. [13] ) enable users to tailor graphical information presentations, called "visualizations", to their needs and achieve insights about the information carried by sets of plain numerical data. These insights (see [12] ), would be often a lot more costly, if they were achieved without visualizations. The information retrieval process is a good example for an information search activity also executed within very large but abstract information spaces. While "digging for information" with the help of a computer, users have to perceive a lot of cross references between data items to achieve insights (see e.g. [4]), i.e., to perceive hidden information carried by the relations between complex and often heterogeneous data structures. Therefore it is reasonable to enable IR users to acquire abstract information similarly as Scientific Visualization allows it for numerical data. Information-retrieval user-interface designs published most recently head into a similar direction. The term "Information Visualization", describing a new medium for visual communication of abstract information in a humancomputer information process, has been created. Different perspectives on data sets and correlations of different data dimensions into one display perspective (see e.g. [8]) are provided. Visualization components supporting the demands of a highly interactive information process are currently under research and development (e.g. [1], [3], [6] and [15] ). Such visualization work was restricted to 2 or 2 1/2D graphics for a long time because graphics systems available could not cope with more dimensions. This has now changed very significantly. High-end computer systems and software tools of the most recent past provide the necessary performance to visualize real-time animated 3D scenes in reasonable qualities (e.g. [14] based on [16]). Manufacturers have committed to supply low-cost workstations with today's high end performance measures within the next two years. For such reasons designing visualizations on 3D graphics workstations offering the highest degree of freedom to visually communicate information is strongly demanded. LYBERWORLD -AN EXAMPLE SESSION IR research ([see 10]) has realized that many IR user interfaces are suffering from problems related to the user's perception and understanding of the information dialog between user and system. The user can neither understand
