• INTRODUCTION
• Our group at the University of Victoria is
  developing a visualization framework for the
  National
• Center for Biomedical Ontology (NCBO) as part of
  the BioPortal initiative. This framework will
• consist of three key components
• 1. a visualization toolkit
• 2. a visualization ontology and
• 3. a mapping mechanism for specifying how to
  integrate and customize the available
  visualization services for particular ontologies
• We are building visualizations to support
• ontology navigation and searching
• ontology alignment and comparisons
• annotations and meta-data analysis

• DIaMOND Degree of Interest Modeling for
  Ontology Navigation and Development.
• Goals
• Monitor user activity to determine concepts of
  interest
• Provide adaptive visualizations to help users
  more efficiently navigate ontologies
• Highlight interesting and landmark concepts
• Filter uninteresting concepts

• Ontology Based Exploration of Clinical Trials
• Goals
• Find new relationships, trends, gaps in clinical
  trials by using multidimensional visualization
  techniques
• Provide feedback to the clinician to support the
  design of further trials

• Visualizing ontology alignment operations in
  Prompt
• Goals
• Provide a structural context for the operations
  being performed
• Provide filters to help the user focus on the
  most important operations

• Visualizations on BioPortal
• Goals
• Develop applet versions of the existing tool
  Jambalaya to
• determine requirements for future web-based
  visualizations
• Provide visualizations showing ontology
  overviews
• Create views to emphasize hub concepts
• Query views to provide visual support for
  searching ontologies
• and displaying results
