Web Site Database Navigation Knowledge base anatomy relational

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 Annotation layer • Hyperlinked texts • Movies • Sounds, etc Semantic layer • Medical lexicons • Semantic relations • Links to regions, volumes, and annotations Anatomical layer • 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) • 3 D 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
