Purpose of this session

• Identify benefits of upper ontologies

• Identify benefits of aligning existing upper ontologies

• Identify requirements for upper ontologies

• Identify research issues

3

Purpose of this session

• Identify benefits of upper ontologiesIdentify applications where the use of an upper ontology gives– improved efficiency in system creation and/or – better system performance in terms of better reasoning

or retrieval etc.• Identify benefits of aligning existing upper ontologies

for improving interoperability among applications • Identify requirements for upper ontologies

from the perspective of (potential) adopters• Identify research issues on the path towards

meeting application requirements and interoperability

Agenda

9:10 AM - Upper Ontologists: Application examplesCyc applications – Doug Lenat, CycorpSUMO applications – Adam Pease, Articulate SoftwareISO 15926 applications – Matthew West, ShellDOLCE applications – Nicola Guarino

ChargePresent an example where the use of an upper ontology

made a real difference in practice; Help those not steeped in logic understand the need for

formalization and axioms; Illustrate the importance of aligning existing upper ontologies

to achieve interoperability among practical applications.
