CONCLUSIONS WHAT IS NEEDED

• STORAGE
• Client/server AND web architecture
• CLASSIFY multiple-access points
• SUBJECT (Open Directory Category)
• Indexed RELATIONS with superset/subset
• Lattice structure (Ontolingua) relation and
  relevance
• Upper-level ontology (ONIONS)
• CORE Peripheral Library using DIMENSIONS
  (task/method domain dependencies)

19
CONCLUSIONS - STORAGE

• SUPPORT FEATURES
• Design process
• Taxonomy
• Axioms
• Inference Mechanism
• Application
• Contributions
• General

20
CONCLUSION - STORAGE

• COMPONENTS
• Domain partitioning
• Alternative domain views
• Abstract / Detailed views
• Primary / Secondary ontological views
• Terminological information
• Knowledge-modeling views

21
CONCLUSIONS - STORAGE

• Modular organization
• Naming policies and standards
• Disjointed partitioning of classes
• Consistency checks
• Unique identification URL, ID, name
• Version control (SHOE)

22
CONCLUSIONS - ADAPTATION

• Visualized browsing
• Hyperlinks and/or cross-references
• Searching and Editing
• Collaborative editing
• Simple REASONING function
• Facilitate ontology creation
• Support ontology mapping and integration

23
CONCLUSIONS - STANDARDIZATION

• LANGUAGE
• Common vocabulary
• Faceted taxonomy
• Controlled Domain vocabularies
• Synonym-matching
• Sibling analysis
• Disjoint partition checking
• Mapping between multiple controlled vocabularies
  from different domains

24
CONCLUSIONS - STANDARDIZATION

• UPPER-LEVEL ONTOLOGY
• Better top-level organization
• Ontolingua
• IEEE SUO

25
CONCLUSIONS - OTHERS

• Ontology SCALABILITY
• MAINTENANCE facilities
• Consistency checking
• Diagnositc testing
• Support for multiple-system interfaces
• Explicit DOCUMENTATION

26
MY ASSESSMENT

• Good, straightforward survey
• PAPER PURPOSE - to present their conclusions
• ADDITIONAL CONCLUSIONS
• Good editors for all views of an ontology
• Well-developed language component (WordNET)
• COMPONENT BUILDING BLOCKS better definition of
  the smallest ontological piece for re-use
• DEPTH-FIRST development (law or medicine)
