New Features in the UMLS Terminology Services

The National Library of Medicine (NLM) is pleased to announce two new UMLS Terminology Services features:

• Create and download lists of concepts or codes
• Search and browse hierarchies for specific UMLS source vocabularies

Create and download lists of concepts or codes

Users can create, save, and download lists of UMLS concepts or codes from UMLS Terminology Services. To access your lists, look for the "My Lists" button at the top of the page within the blue banner (Figure 1).

To add a concept or code to a list, click on theicon next to the concept or code that you want to add to a list (Figure 2). In the pop-up box, type in the name of your new list or select the list you want. The concept or code will be added to your list. Follow the link to check out the concept “Diabetes Mellitus” in the UMLS Metathesaurus Browser and test out adding a concept to a list.

Search and browse hierarchies for specific UMLS source vocabularies

Users can now search and browse hierarchies for UMLS vocabularies from the UMLS Metathesaurus Browser.

Figure 3: Search results for "HIV" in SNOMED CT, US Edition hierarchy

For example, Figure 3 displays a search for "HIV" in the SNOMED CT, US Edition hierarchy, which is selected on the left. The resulting hierarchy in the middle of the page can be expanded and contracted by selecting the + and - symbols. Bolded text indicates where your search term appears in the hierarchy. Select a term, such as "Blood vessel finding" in Figure 3, and more information will appear on the right-hand panel. You can find additional hierarchical information on a page for a specific code.
