Core 2: Bioinformatics
NCBO-Berkeley
Core 2 Specific Aims
1. Apply ontologies

Software toolkit for describing and classifying
data
2. Capture, manage, and view data
annotations

Database (OBD) and interfaces to store and view
annotations
3. Investigate and compare implications

Linking human diseases to model systems
4. Maintain

Ongoing reconciliation of ontologies with
annotations

Elicitation of Requirements for
Annotation Tools
 Applications pull from pioneer users in Core 3
 ZFIN
 FlyBase
 Trial Bank
 Study these groups currently annotate data
 Determine how our Core 2 tools can integrate with
existing data flows and databases
 Evaluate the commonalities and differences among
approaches
Development of
Data-Annotation Tool
 Develop plug-in architecture
 Default user interface for generic data-annotation
tasks
 Custom-tailored interfaces for particular
biomedical domains
 Enable interoperability with existing ontologymanagement platforms
 Integrate ontology-annotation tool with
BioPortal
 Access ontologies for data annotation from OBO
 Store data annotations in OBD
Creating associations
context
Phenotypic
observation
environment
evidence
publication
figures
assay
genetic
sequence ID
ontology
Definition of an association
Association = Genotype Phenotype Environment Assay
Phenotype = Stage* Entity Attribute Entity* Measurement*
Measurement = Unit Value (Time)
Entity = OBOClassID
Attribute = PATOVersion2ClassID
Our Annotation Task
 Annotation: describing an instance with
a set of associated ontological terms
 Genotype, environmental, assay,
evidence, and phenotype
 For an association we need to capture
the following data:
1. A name or tag for the instance
2. The evidence for the observation
 For example, the URL of an image
3. A list of associated terms comprising the
annotation
