National Cancer Institute Center for Biomedical Informatics and Information Technology (CBIIT)
NCI Term Browser 2.10 Release Notes
October 2016

Overview

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.

Support:
See JIRA NCI Thesaurus (NCIt) Browser / Term Browser project.

Release 2.11 features

The NCI Term Browser 2.9 release provides ...

NCITERM-702- Upgrade to JAVA 8

NCITERM-762- Migrate to LexEVS 6.5

 

Bugs Fixed Since Last Release

NCITERM-754 - NCIt hierarchy breaks on OWL2 load

NCITERM-755 - ALT-DEFINITION sources in OWL2 formatted ontologies are not showing

Important Remaining Issues

NCIt Advanced Search - The NCIt advanced search will not currently return results when a source is selected.  This will be fixed in a patch release that will be deployed soon.

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.

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 after approximately 60 minutes of inactivity.

View in Hierarchy - Top nodes of ICD-10 loaded by the Classification Mark-up Language (ClaML) loader cannot be viewed in the View in Hierarchy.

GUI abnormalities - On Internet Explorer browser releases prior to version 11, the application's border formatting is a little off on the home page.

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

Mapping iterator issue (LEXEVS-961) - If NCI Term Browser is configured to run using the distributed LexEVS API, the iterator returned by the mapping search will not advance.  This behavior is not observed when the Term Browser is configured to run with a local instance of the LexEVS server, which is the configuration used at NCI.

Earlier releases of Firefox sometimes produce an error when clicking the back button (NCITERM-695)- From the search results page, going to a concept details page and then clicking on the back button to get back to search results will sometimes result in a "Document Expired" error.  This has been found using the Firefox browser releases 38.2.1 and ESR 38.6.1.

View Graph issue for NCI computers using Internet Explorer 11 - We have discovered that some NCI computer users are being blocked from the View Graph display when using Internet Explorer 11.  We are currently looking into the issue and hope to find a solution.  For now, if you are having trouble with the Graph View we recommend using Firefox.

 

Known issues

NCITERM-428 - Concept Code search on Mappings tab is case sensitive.

NCITERM-434 - Anonymous concepts appear in value sets.

NCITERM-441 - NCI Term Browser error message

NCITERM-695 - Back button producing "Document Expired" error
