Ontology / Class

• Here is a structured dataset. Let’s call it ontology.
• The example is visualizing a conceptual model of pizza, the “ontology” of pizza.
• In the example, “Pizza” is a type of “Food”.
• And also, “Food” is a type of “Thing”.
• Let’s call those concepts classes of the ontology.

Mapping

• Here are two ontologies visualized side by side.
• Classes with same meaning between ontologies are connected.
• Let’s call the connection mapping.
• “Pizza” on the left ontology is mapped to “pizza” on the right ontology.
• A line is showing the mapping between “Pizza” and “pizza”.
• The lines are showing the mappings.

Ok, now what will I do?

• You will see a visualization of mappings between two ontologies about “conference”
• Complete a task about the mappings using the visualization.
