The next NCBO Webinar will be presented by Dr. James Geller from the New Jersey Institute of Technology on “The Neighborhood Auditing Tool for the UMLS and its Source Terminologies” at 10:00am PDT, Wednesday, October 20.

ABSTRACT:

The UMLS’s integration of more than 100 source vocabularies makes it susceptible to errors. Furthermore, its size and complexity can make it very difficult to locate such errors. A software tool, called the Neighborhood Auditing Tool (NAT), that facilitates UMLS auditing is presented. The NAT supports “neighborhood-based” auditing, where, at any given time, an auditor concentrates on a single focus concept and one of a variety of neighborhoods of its closely related concepts. The NAT can be seen as a special browser for the complex structure of the UMLS’s hierarchies. Typical diagrammatic displays of concept networks have a number of shortcomings, so the NAT utilizes a hybrid diagram/text interface that features stylized neighborhood views which retain some of the best features of both the diagrammatic layouts and text windows while avoiding the shortcomings. The NAT allows an auditor to display knowledge from both the Metathesaurus (concept) level and the Semantic Network (semantic type) level. Various additional features of the NAT that support the auditing process are described. The usefulness of the NAT is demonstrated through a group of case studies. Its impact is tested with a study involving a select group of auditors.

Deeply edited version from NCBO Webinar – James Geller, October 20 at 10:00am PT, which has numerous other details.

If you translate “integration” as “merging,” the immediate relevance to topic maps and exploration of data sets becomes immediately obvious.
