Gene Ontology

"The Gene Ontology project is a major bioinformatics initiative with the aim of standardizing the representation of gene and gene product attributes across species and databases. The project provides a controlled vocabulary of terms for describing gene product characteristics and gene product annotation data from GO Consortium members, as well as tools to access and process this data."

Foundational Model of Anatomy

"The Foundational Model of Anatomy Ontology (FMA) is an evolving computer-based knowledge source for biomedical informatics; it is concerned with the representation of classes or types and relationships necessary for the symbolic representation of the phenotypic structure of the human body in a form that is understandable to humans and is also navigable, parseable and interpretable by machine-based systems. Specifically, the FMA is a domain ontology that represents a coherent body of explicit declarative knowledge about human anatomy.

Experimental Factor Ontology

"The Experimental Factor Ontology (EFO) provides a systematic description of many experimental variables available in EBI databases, and for external projects such as the NHGRI GWAS catalogue. It combines parts of several biological ontologies, such as anatomy, disease and chemical compounds. The scope of EFO is to support the annotation, analysis and visualization of data handled by the EBI Functional Genomics Team. We also add terms for external users when requested."

Comparative Data Analysis Ontology

"CDAO stands for "Comparative Data Analysis Ontology", a formalization of concepts and relations relevant to evolutionary comparative analysis, such as phylogenetic trees, OTUs (operational taxonomic units) and compared characters (including molecular characters as well as other types). CDAO is being developed by scientists in biology, evolution, and computer science. In general, ontologies are designed to support formal or automated reasoning. Our aim in developing CDAO is to provide the language support for representing, and reasoning over, phylogenetic data and metadata.

Environment Ontology

"The Environment Ontology (EnvO) provides a controlled, structured vocabulary that is designed to support the annotation of any organism or biological sample with environment descriptors. EnvO contains terms for biomes, environmental features, and environmental material." EnvO enables "a concise, standardised, and comprehensive description of environment that is key to the integration, archiving and federated searching of environmental data. As a tool for the life sciences, we see EnvO bringing benefits similar to those of the Gene Ontology (GO).

Emotion Ontology

"The Swiss Centre for Affective Sciences, in collaboration with the University at Buffalo, is developing an Emotion Ontology to describe affective phenomena. This project is a branch of the broader Mental Functioning ontology effort. The Centre brings together scientists from neuroscience and psychology, together with economists, historians, philosophers as well as scholars in the humanities, in a multi-disciplinary effort to understand how affective phenomena, such as motives, attitudes, moods, and emotions, affect the individual and society.

Chemical Entities of Biological Interest

"Chemical Entities of Biological Interest (ChEBI) is a freely available dictionary of molecular entities focused on ‘small’ chemical compounds. The term ‘molecular entity’ refers to any constitutionally or isotopically distinct atom, molecule, ion, ion pair, radical, radical ion, complex, conformer, etc., identifiable as a separately distinguishable entity. The molecular entities in question are either products of nature or synthetic products used to intervene in the processes of living organisms.
