Web Site, Database, Navigation

• Knowledge base = anatomy, relational database, annotations

• Lecture, quiz, tour, etc = collaborative navigation of knowledge space

• Current task =build the relationaldatabase

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
