The NCI Thesaurus quality assurance life cycle

Abstract

The National Cancer Institute Enterprise Vocabulary Services (NCI EVS) uses a wide range of quality assurance (QA) techniques to maintain and extend NCI Thesaurus (NCIt). NCIt is a reference terminology and biomedical ontology used in a growing number of NCI and other systems that extend from translational and basic research through clinical care to public information and administrative activities. Both automated and manual QA techniques are employed throughout the editing and publication cycle, which includes inserting and editing NCIt in NCI Metathesaurus. NCI EVS conducts its own additional periodic and ongoing content QA. External reviews, and extensive evaluation by and interaction with EVS partners and other users, have also played an important part in the QA process. There have always been tensions and compromises between meeting the needs of dependent systems and providing consistent and well-structured content; external QA and feedback have been important in identifying and addressing such issues. Currently, NCI EVS is exploring new approaches to broaden external participation in the terminology development and QA process.

Uberon, an integrative multi-species anatomy ontology

“…Further complicating this picture are dedicated ontologies that specialize in a particular anatomical system-for example, the Neuroscience Information Framework (NIF) Gross Anatomy, part of the NIF Standard suite of ontologies, represents neuroanatomy [9], integrating a range of brain atlases and databases. Other ontologies such as GALEN [10] and the National Cancer Institute Thesaurus [11] are not strictly anatomical ontologies, but include AOs as sub-ontologies.…”

The development of non-coding RNA ontology

“…NCI Thesaurus (NCIt): NCIt (De Coronado et al, 2009) is a reference biomedical ontology published by the National Cancer Institute (NCI). NCIt terminology includes clinical care, translational & basic research, and public information and administrative activities.…”

Case Study

“…Basic concepts can be combined to represent more complex ideas. 7 Concepts are identified with an alphanumeric code (e.g. C16696) and a definition that helps differentiate terms like discharge, when meaning leaving the institution, versus when the word means wound drainage.…”
