Abstract
The Controlled Health Thesaurus (CHT) is a controlled vocabulary that was developed by the Centers for Disease Control and Prevention (CDC) to support the automated indexing and retrieval of public health content on the CDC web site. The CHT evolved from four vocabularies contained in the Unified Medical Language System (UMLS) of the National Library of Medicine (NLM). As the CHT has evolved, terms have been added to both the CHT and the UMLS. We undertook a study to identify those terms in the CHT which could be mapped to the UMLS but which currently do not have an assigned UMLS Concept Unique Identifier (CUI). We employed automated methods to generate, display and semantically validate proposed UMLS CUI mappings. Our efforts identified 408 terms in the CHT that have semantically valid UMLS CUI mappings, and we propose that these mappings could be considered for inclusion in the CHT.
