Human Phenotype Ontology

"The Human Phenotype Ontology (HPO) aims to provide a standardized vocabulary of phenotypic abnormalities encountered in human disease. Each term in the HPO describes a phenotypic abnormality, such as atrial septal defect. The HPO is currently being developed using the medical literature, Orphanet, DECIPHER, and OMIM. HPO currently contains approximately 11,000 terms and over 115,000 annotations to hereditary diseases. The HPO also provides a large set of HPO annotations to approximately 4000 common diseases.

Global Agricultural Concept Scheme

"GACS explored the possibility of creating a global repository of concepts and terminology in the area of agriculture. This first beta is the result of the first experimental attempt, and it went very well! We now have a pool of concepts based on a mapping between AGROVOC, the CAB Thesaurus and the NAL Thesaurus. An analysis of the the coverage of GACS beta with respect to AGROVOC showed that it could already be used to index AGRIS, with no significant loss of indexing concepts."

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.


"Comprehensive and polyhierarchically structured, Emtree provides a consistent description of all biomedical terminology, allowing unrivaled drug and disease indexing.

CAB Thesaurus

"The CAB Thesaurus is the essential search tool for all users of the CAB ABSTRACTS™ and Global Health databases and related products. The CAB Thesaurus is not only an invaluable aid for database users but it has many potential uses by individuals and organizations indexing their own information resources for both internal use and on the Internet.
