Description in brief Controlled vocabulary created by BIREME in 1982, fully compatible with MeSH (“Medical Subject Headings”, produced by the U.S. National Library of Medicine (NLM), is a controlled vocabulary used for indexing and recovering information in MEDLINE / Pubmed) DeCS – the Portuguese acronym for Descritores em Ciências da Saúde (Health Sciences Descriptors) Yearly updated (idem MeSH) Currently available in Portuguese, Spanish and English Composed of 16 MeSH Categories plus 4 thematic terminology categories: Public Health, Health Surveillance, Homeopathy, and Science & Health An integrating component of the VHL and GHL - Allows meta-searching by descriptor, ie, searches multiple IS - Allows multilingual searching DeCS/MeSH description in brief uses description categories / numbers types of terms descriptors synonyms qualifiers check-tags publication types characteristics trilingual polyhierarchical postcoordination precoordination services for users documentation browser help record view word search exact term index view alphabetical i. kwic i. tree i. configuration for computer applics. search by tree code word or term lexical similarity occurrences in VHL alphabetical ruler availability/licensing user support update number of accesses

8. Synonyms Also known as Used For (UF) terms, Cross-references or Entry terms They mean the same or nearly the same as the descriptor (EQV, NRW, BRD, REL). They are used as alternate terms in search expressions, obtaining the same search result. For the system they are considered equivalent.

Language versions DeCS is trilingual (English, Spanish and Portuguese) DeCS’ Spanish and Portuguese terms are exported to the UMLS metathesaurus (Unified Medical Language System) and distributed as Spanish MeSH and Portuguese MeSH To date, there are 11 MeSH translations incorporated into the UMLS Metathesaurus DeCS/MeSH description in brief uses description categories / numbers types of terms descriptors synonyms qualifiers check-tags publication types types of relations characteristics trilingual polyhierarchical postcoordination precoordination services for users documentation browser help record view word search exact term index view alphabetical i. kwic i. tree i. configuration lexical similarity occurrences in VHL alphabetical ruler availability/licensing for computer applics. search by tree code word or term lexical similarity user support update number of accesses

16. Polyhierarchical A descriptor may belong to more than one category or to several branches of the same category due to the multidisciplinary nature of many concepts. Example: Ethics belongs to the F, K and N categoriesEthics F = Psychiatry and Psychology; K = Humanities; N = Health Care DeCS/MeSH description in brief uses description categories / numbers types of terms descriptors synonyms qualifiers check-tags publication types types of relations characteristics trilingual polyhierarchical postcoordination precoordination services for users documentation browser help record view word search exact term index view alphabetical i. kwic i. tree i. configuration lexical similarity occurrences in VHL alphabetical ruler availability/licensing for computer applics. search by tree code word or term lexical similarity user support update number of accesses Related documents in the VHLVHL

17. Postcoordination Descriptor + Descriptor Descriptor + Qualifier Descriptor + Check tag Descriptor + Publication Type The act of coordinating two or more concepts at the moment of searching for literature with the objective of narrowing the scope of a subject. The DeCS/MeSH vocabulary permits four types of terminological postcoordination.
