  Modular Ontologies Jie Bao, Doina Caragea, Vasant
  Honavar

  Relations with Alignment Composition Antoine
  Zimmermann, Jérôme Euzenat (NeOn project)

7
What is learnt from WoMo

• There is no universal standard to say what is
  good modular ontology
• Structural, semantic, conservative extension
• P-DL is unique on knowledge transitive reuse
• P-DL and semantic importing by Jeff Pan et al can
  be merged
• Partial reuse might be a concern reusing by name
  or by axiom? Propagate all or selected axioms?

  things easier to say DisjointUnion, valueNot
• New Description Logic constructs SROIQ
• qualified cardinality restrictions allowing
  constructions like ObjectMinCardinality(2
  friendOf hacker)
• local reflexivity restrictions on non-complex
  properties only, allowing constructs like
  ObjectExistsSelf(likes) for narcissists
• reflexive, irreflexive, symmetric, and
  anti-symmetric properties for non-complex
  properties only, allowing constructs like
  ReflexiveObjectProperty(knows) and
  IrreflexiveObjectProperty(husbandOf)
• disjoint properties for non-complex properties
  only, allowing constructs like DisjointObjectPrope
  rties(childOf spouseOf) and
• property chain inclusion axioms allowing
  constructs like SubObjectPropertyOf(SubObjectPrope
  rtyChain(owns part) owns), provided that no
  cyclic inclusions result.
• expanded datatype expressiveness user-defined
  datatypes

  Person) can be used as any or all of an
  individual, a class, or a property
