Biological and Medical Ontologies: Disease Ontology (DO)

Human Disease Ontology (DO) is a standardized vocabulary for annotating and classifying diseases and their clinical features. It includes over 18,000 disease concepts (classes) and is organized hierarchically, with each concept representing a specific disease or condition. The DO is designed to facilitate the exchange and integration of disease-related information and to support the identification of relationships between diseases. It is widely used in the biomedical community for a variety of purposes, including disease classification, data integration, and knowledge representation.
