DeCS, an acronym for Descriptores en Ciencias de la Salud (Health Sciences Descriptors), is a controlled vocabulary that uses descriptors/headings to index scientific articles and other documents in the biomedical field. Making an analogy, indexing consists of assigning “tags” to documents, which allows them to be retrieved from the database. The descriptors would be those tags. Learn more at About DeCS.
