Graphical Ontology Viewer/Editor

Gary Yngve

Goals

• Easy to use, interactive

• Hide most of the ontology

• Keep user aware of what transformations have been done

• Undo

Basic Architecture

ReferenceOntology

ModificationLayer

Visualizationcache

Features

• Navigation / transformation with mouse– left button navigates, right button transforms– popup menus for making choices

• Query window for more powerful tasks– transitive closure, workspace for chaining operations

• Search window for trying to align terms– uses lucene on FMA

Use Case: RADLEX

• many terms exactly match

• some different partitioning

(regional parts not in FMA)

• much smaller in size than FMA

Idioms

• Common ontology modifications

• For example:– dissecting a vessel prox/dist– eliminating parts and promoting their

relationships to the whole– building a set of items

• Semantics well-defined?

Other stuff

• Filtering non-class slots

• Viz multiple relation types at once

• Selective partitioning

• Degree of importance filtering

• Shorthand for names

• Gestures / lasso

DEMO!

• Aligning, prompt

• Jambalaya. Doesn’t transform, size limit
