where in the body ? where in the cell ?

what kind of disease process ?

5

UMLS, Semantic Web, Moby, wikis, etc.

let a million flowers bloom

integration relies on post hoc mappings

how create broad-coverage semantic annotation systems for biomedicine?

6

for science

create an evolutionary path towards evidence-based terminology

a new approach

7

a shared portal for 60+ ontologies (low regimentation)

CRITERIA

The ontology is open and available to be used by all.

The ontology is in, or can be instantiated in, a common formal language.

The developers of the ontology agree in advance to collaborate with developers of other OBO Foundry ontology where domains overlap.

CRITERIA

http://obofoundry.org/http://obofoundry.org/

18

CRITERIA UPDATE: The developers of each ontology

commit to its maintenance in light of scientific advance, and to soliciting community feedback for its improvement.

ORTHOGONALITY: They commit to ensuring that there is community convergence on a single controlled vocabulary for each domain

http://obofoundry.org/http://obofoundry.org/

19

CRITERIA

IDENTIFIERS: The ontology possesses a unique identifier space within OBO.

VERSIONING: The ontology provider has procedures for identifying distinct successive versions.

The ontology includes textual definitions for all terms.

CRITERIA

http://obofoundry.org/http://obofoundry.org/

20

CLEARLY BOUNDED: The ontology has a clearly specified and clearly delineated content.

DOCUMENTATION: The ontology is well-documented.

USERS: The ontology has a plurality of independent users.

CRITERIA

http://obofoundry.org/http://obofoundry.org/

21

COMMON ARCHITECTURE: The ontology uses relations which are unambiguously defined following the pattern of definitions laid down in the OBO Relation Ontology.*

Ontology vs. Schema

Separate development of medical ontologies and terminologies such as SNOMED

and medical information models and database schemas

Rector, et al., Binding Ontologies and Coding Systems to Electronic Health Records and Messages

32

Ontology vs. Schema

diabetes => disease

diabetes => string

temperature => quality

temperature => integer

33

Valid Specifications for data structures“Valid diabetic data structures have: a topic of code for diabetes, a diagnosis code that is diabetes or one of its subcodes, and a brittleness code that is one of the subcodes for diabetic brittlenes and nothing else”

Ontology“All diabetes are metabolic diseases”“John has diabetes & it is brittle and long-standing”

You are a continuant
