2. 06-2008 FAO-FIES Y. Jaques What are ontologies? networks of concepts and relationships taxonomies (parent/child) are just one type of relationship that can be modeled includes order includes family includes species

3. 06-2008 FAO-FIES Y. Jaques How are ontologies written? expressed using a modelling language such as XML-based OWL: using editors such as NeOn NTK, Protégé, Top Braid Semantic Works and Swoop.

4. 06-2008 FAO-FIES Y. Jaques Some OWL terminology Classes a.k.a. concepts Object Properties a.k.a. relations Individuals a.k.a. instances Datatype properties a.k.a attributes Centrolophus niger SPECIES FAMILY includes species Rudderfish has name THING CEO has FAO alpha code

5. 06-2008 FAO-FIES Y. Jaques Ontologies are very expressive relationships can be constrained in many ways:

6. 06-2008 FAO-FIES Y. Jaques How are ontologies useful? Languages like OWL create a standard syntax for describing hierarchies, taxonomies and classifications. Many existing applications can edit, interpret and display OWL models. Dissemination and sharing of models becomes simpler and more standardized. Standard web services enable ontology discovery and distribution. Local ontologies can be mapped to standard ontologies (we can agree to disagree)

7. 06-2008 FAO-FIES Y. Jaques How can they be shared? New platforms such as NeOn allow for the distributed maintenance of ontologies, and cross mapping of multiple ontologies. User rights and versioning workflows allow for ontology evolution. Registries and repositories allow for discovery and access.

8. 06-2008 FAO-FIES Y. Jaques How can they be networked? Powerful visualisation tools allow for easy understanding of the model:

9. 06-2008 FAO-FIES Y. Jaques How can they be networked? Cross-mapping tools allow for easy networking and extension of multiple ontologies: My ontology Y(our) ontology mapping rules

10. 06-2008 FAO-FIES Y. Jaques How can they be applied? Semantically-aware applications can understand OWL models out of the box. Attached to databases they become a knowledge base, able to perform primitive inductive and deductive reasoning. Other advantages can be query disambiguation as well as synonym, hyponym and multi-lingual searches
