– Example of concept-based vs literal translation approach

As the ontology may contain errors, it is important that translators are aware of possible inconsistent or erroneous formal relationships and report modelling that contradicts the FSN.

SNOMED CT is a comprehensive terminology designed to meet the needs of a broad group of health care professionals in a range of settings. Translations should comply with the principles on which SNOMED CT was originally based:understandability, reproducibility and usefulness (URU). Therefore, the translation should adhere to the principles elaborated by Terminology Science for useable terms: terms should be transparent and reflect the essential characteristics of the designated concept; terms should satisfy the requirements of the users’ needs, i.e. they should be in accordance with clinical usage and they must be equally well understood by the different health professionals who use them. For each target language national linguistic guidelines, including syntactic, morphological and orthographic rules, are developed to support this approach.
