Slide 2
Visualizing Mappings between Terms and between Ontologies

Slide 3
CogZ Cognitive Support and Visualization for Human- Guided
Mapping Systems
Slide 4
Ontology alignment Mapping terms from one ontology to another,
preserving structural relationships Research emphasis mostly on the
algorithm Select ontologies Alignment algorithm Potential mappings
Verified mappings Mapping complete
Slide 5
Ontology alignment continued Cognitively challenging The user
must: Make decisions about mapping candidates Supply custom
mappings that were missed Understand the domains and structure of
both ontologies Remember decisions that were made Can be made
easier through cognitive support
Slide 6
Visualization plug-in for Prompt Prompt: framework to support
ontology alignment Added a plug-in mechanism and perspectives to
Prompt to support other algorithms and visualizations CogZ:
Integrating various visualizations and filters to support the users
decision making process

Slide 15
Mappings between NPO and other ontologies
Slide 16
Visualization requirements for Nanoparticle ontology?
Exploration, navigation, search? Support error checking? Changes
across ontology versions? Publication and syndication of changes?
Distinguish between original and imported classes/ontologies (upper
versus domain ontologies)? Distinguish actual from inferred
relations? Mappings? Support for alignment? Scalability? Is NPO
stable in terms of size? Non graph views? e.g. charts?
Collaboration features? Need for embeds? 16
