What is an anatomical ontology?
![Page 3: Uberon EBI industry workshop](https://reader035.vdocuments.net/reader035/viewer/2022062405/5550135bb4c905af648b4a3b/html5/thumbnails/3.jpg)
Anatomical data annotation
![Page 4: Uberon EBI industry workshop](https://reader035.vdocuments.net/reader035/viewer/2022062405/5550135bb4c905af648b4a3b/html5/thumbnails/4.jpg)
Uses of anatomical ontologies
• Transcriptome data– Genes expressed in hippocampal CA1 region
• Describing clinical phenotypes– Loss of beta cells in the pancreas
• Biospecimen annotation– Liver-derived sample
• Functional characterization of gene products– BMP4 involved in bone development
• Describing species diversity– Extant avians lack teeth but have feathers
• NLP and text processing
![Page 5: Uberon EBI industry workshop](https://reader035.vdocuments.net/reader035/viewer/2022062405/5550135bb4c905af648b4a3b/html5/thumbnails/5.jpg)
More than a terminology
• Use of is-a (Sub Class Of)– Tell me about phenotypes that affect
bone growth• Answers include femur growth phenotypes
• Use of part-of–Which genes are expressed in the
hippocampus• Answers include genes expressed in CA1
region

Use of relationships in anatomical ontologies
• Use of develops-from– Cancers of neural-crest lineage cells?
• Answers include melanocytomas
• Use of other relationship types– Structures are made from connective
tissue?– Branches of the trigeminal nerve?– Brain regions associated with ataxia?– Neurons that secrete dopamine?– Brain regions near the striatum?

Which ontology?
• Mouse:– MA (adult)– EMAP (embryo, staged)– EMAPA (embryo,
abstract)
• Other models– XAO - Xenopus– ZFA – zebrafish– FBbt – Drosophila– WBbt – C elegans– DDAnat – Dictyostelium– …
• Human– FMA (adult)– EHDAA2 (CS1-
CS20)– SNOMED-CT– NIF GrossAnatomy
(mammal brain)– …

Why not just select one and adopt it as the
standard?

Linking animal models to human disease through a multi-species anatomy ontology
• Initial Approach:– Generalize existing species-specific
anatomy ontology terms– Use these as a bridge to connect data

Uberon: a multi-species anatomy ontology
• Contents:– 11,000 classes (terms)–Multiple relationship types, including
subclass (is-a), part-of and develops-from
– Detailed OWL axiomatization
• Scope: metazoa (animals)– Current focus is chordates
• Particularl emphasis on mammalia
– Federated approach for other taxa

Uberon for NLP and text mining
• Lexical contents– 11414 primary labels– 29753 synonyms• Classified by category (broad, narrow, exact,
related)• Tagged with source• Additional synonym types (abbreviations,
formal Latin term, plural, etc)
– 270 adjectival forms• E.g. “hippocampal”

Uberon as a bridge between anatomy ontologies
• Cross-references to– FMA (4627)– Human developmental anatomy [Bard et al] (1463)– Multiple model organism anatomy ontologies (15256)
• MA, ZFA, etc
– Allen Brain Atlas (273)– NIF Neuroanatomical Ontology (1013)– SNOMED-CT (3453)– UMLS (2189)– NCI thesaurus (2286)– Wikipedia/Dbpedia (2966)– EFO (616)– …
• Cross-references are curated and validated– Manually– Through OWL reasoning

Bridging orthogonal resources
• Validated logical relationships connecting– Cell types (OBO Cell Ontology, CL)– Taxonomy (NCBI)– Functional and developmental
knowledge (GO)– Behaviors (NBO)– Proteins (PRO)– Chemical entities (CHEBI)

Challenge: building the right view
• An ontology built for multiple purposes will usually be more complex than one built for one purpose– Most people don’t need the whole ontology
• Solution: create subsets or views– Based on
• Taxonomy (e.g. mouse plus human)• Organ system (e.g. skeletal)• Domain (e.g. diabetes)

Latest developments
• Evolution of ontology– Initial goals: primarily a mapping resource– Now: Data is being annotated to Uberon directly
• Gene expression, transcriptomic, phenotype, functional
• The big roll up– Community converging around a single solution– Multiple ontologies being absorbed
• Anatomy subset of EFO• Neuro-Anatomy subset of NIFSTD• CALOHA (NextProt)• vHOG (Bgee gene expression db)• VSAO (Evolutionary biologists)

Summary
• Multiplicity of ontologies causes problems– Duplication of effort– Data silos
• Uberon bridges across species-specific anatomical ontologies– Can function as a standalone vertebrate anatomy
ontology
• A common multi-species anatomy ontology can bridge multiple datatypes– Gene expression– Phenotype– …
