NCI Thesaurus Browser 2.1 Release Notes
June 11, 2012


NCI Term Browser provides a consistent, user-friendly tool to browse and search all of the biomedical terminologies hosted by NCI EVS, including both NCI Thesaurus (NCIt) and the NCI Metathesaurus (NCIm), which itself includes more than 70 terminologies. These terminologies normally represent each specific meaning, such as melanoma, lung, or chemotherapy, by a distinct concept with a unique, permanent code. Each concept normally provides additional information such as a preferred name, other terms and codes, definitions, and relationships with other concepts. Concepts are normally organized in parent-child hierarchies from very broad top concepts down to the most specific subcategories. All browsing and searching in this browser reflects this concept-based view of terminology.

Important Remaining Issues

Cart functionality behavior for multiple terminologies -  You may save visited concepts to a cart and export these concepts to a file in either LexGrid XML format or Comma Separated Values (CSV) format at a later time. Because the browser supports multiple versions of the same terminology (for example MedDRA 12.0 and 13.1), you will be prompted for the terminology version when you are ready to export concepts in carts. Please be aware that if a concept in the cart is not found in the version of the terminology you specified, then you should not expect the concept to appear in the file. For example,  the MedDRA concept Traumatic renal injury (Code 10070510) appears in MedDRA 13.1, but not in MedDRA 12.0. So, if you visit the concept, save it to the cart, then try do an export, selecting 12.0 as MedDRA version, then you won’t find this concept in the export.

Concept Code search on Mappings tab is case sensitive -The Mappings Concept Code search is case sensitive.  For example, if a user is on the Mapping tab and does a Concept Code search on go:0006200, the search will come back empty.  The user will need to do the same search using uppercase letter (GO:0006200) to get the result back. This is something we plan on fixing in a future release.

Search box on the Value Set tab Terminology View and Source View pages - Please be aware that the sole purpose of the search box on the Terminology View and Source View pages is for finding Value Sets containing at least one concept that match with your search criteria. So, search results would remain the same if no search criteria is changed when you perform a search on these pages. To search against a particular matched value set returned by the above search, you should click on a matched value set hyperlink to go to its home page and then perform search there.

Session timeouts - Be aware that if you leave the browser open for long periods of time you will get a session timeout.  Although you should still be able to search, persisted functionality such as the concept cart and pagination of search results will timeout in approximate 60 minutes.

View in Hierarchy - Top nodes for claml loaded ICD cannot be viewed in the View in Hierarchy.

Note: Although compatible with Internet Explorer, the Term Browser works best when using the latest version of Firefox web browser.
