NCI: The NCI Thesaurus is a product of NCI's Enterprise Vocabulary Services. It arose from the need to have an institute wide common terminology to integrate the diverse data systems in use throughout NCI. Centralized coding of research related activities helped to meet various responsibilities of the Institute; however, supplementary data coding assigned independently by various components of the NCI made it difficult to find and combine related information across programs. By incorporating the terms in use by the various programs and mapping those to unique concepts, it was intended that the NCI Thesaurus would facilitate interoperability and data sharing within NCI. The NCI Thesaurus is a rigorous, cancer-centric, formal reference vocabulary with true is_a taxonomic structure, polyhierarchy, inferred partonomy, and other features that make it suitable for supporting complex query operations against appropriately coded data repositories.,HL7V3.0: <p>NCI Thesaurus NCI Thesaurus is a biomedical thesaurus crea
