Web Site, Database, Navigation Knowledge base = anatomy, relational database, annotations Lecture, quiz, tour, etc = collaborative navigation of knowledge space Current task = build the relational database

Other “Show and Tell” Web site, phase 1, in a stable and mature state Collaborative tools from Pittsburgh and through the use of Course Tools Building up a collection of multi-media examples

Visible Human Knowledge Base Anatomical layer Semantic layer Annotation layer Hyperlinked texts Movies Sounds, etc Medical lexicons Semantic relations Links to regions, volumes, and annotations Labels of structures Voxel data and segmentation Volume surfaces Spatial relationships

Anatomical Layer Presentation of click-able slice data (click to get full three-dimensional coordinate) 3D coordinate used to index –Segmentation and label –Volume/Surface descriptions –Index into Semantic Layer Spatial relations to navigate to Anatomical Layer level

Semantic Layer Multiple, related hierarchies of semantic information: labels and relations A “navigation space” for relational information Needs to be made accessible on the web –Automatic web page generation for primitive navigation?

Annotation Layer Multi-media annotations Developed from prototypes and scenarios given by UI group With links into database
