NCI LexEVS 5.0 retired

Announced May 2, 2012
Retirement of NCI's LexEVS 5.0 terminology server instance is now scheduled for May 3, 2012. LexEVS 5.0 has been deprecated since late 2010, and previous announcements have encouraged users to migrate to the newer LexEVS 5.1 or 6.0 servers before the original May 1 retirement date.

If you still use the 5.0 server, please contact us at so that we are aware of your needs and can help you migrate. Information about migrating can also be found for 5.0 and 6.0.

Using this ontology Semantator 1.0, a Protege plug-in, can take clinical documents and allow real time annotation. The first release of this annotator can use other annotators in the back-end to semi-automatically flag annotations.

VKC launches its third cloud computing image

Announced February 6, 2012

NCI CBIIT announces caBIG® Community Code Resource Directory

Announced January 31, 2012
The NCI Center for Biomedical Informatics and Information Technology (CBIIT) is pleased to announce the launch of the caBIG® Community Code Resource Directory, a resource intended to promote the exchange of community-developed digital capabilities supporting cancer research.

  • The WHO-IHTSDO memorandum of agreement is official starting at July 2010.
    Announced July 1, 2010
    A Collaborative Arrangement between the International Health Terminology Standards Development Organisation (IHTSDO) and The World Health Organization (WHO) has been officially signed since July 2010.
    The Collaborative Arrangement enables harmonization - as complementary tools - of WHO Classifications and SNOMED CT for the benefit of citizens around the world. When used together appropriately, they make it easier to summarize information from individual patients' health records into aggregated results needed for health policy, health services management, and research. WHO and IHTSDO aim to increase collaboration in order to create and maintain jointly usable and integrated classification and terminology systems to make efficient and effective use of public resources and avoid duplication of effort. This is essential to create health information's standards as a common language worldwide.
    WHO Classifications are used to capture key information on diseases, disability, interventions and other indicators of population's health. Main classifications such as the ICD (International Classification of Diseases), in use for more than 100 years worldwide, provide data on life expectancy, causes of death, and inform the plans and decisions of health authorities in many countries.
    SNOMED CT is a standardized health terminology that represents clinical concepts in a consistent, and comprehensive way in health records. Managed by the IHTSDO, it is used for this purpose and others in countries around the world. Given the emergence of Electronic Health Records (EHRs), the use of standardized terminologies has become more important for meaningful exchange of data in health information systems.
    This collaboration arrangement will be used to build maps and linkages between ICD and SNOMED CT for automated processing of data to improve coding and information exchange. It will also enhance the work on the revision of the ICD for its 11th revision.
    This new arrangement supports the aims of WHO and IHTSDO to enhance health through better health information. Synergies between WHO classifications and SNOMED CT have the potential, through better information, to improve the accuracy, the reliability, and the quality of health and health care; to eliminate gaps in information; and to control costs.
