Controlled Vocabularies: CAB Thesaurus 2017 Edition Now Available (Largest Source of Terminology Covering Applied Life Sciences)

From CABI:

The CAB Thesaurus has received a major update for the 2017 edition, making it easier to access the world’s largest source of terminology covering the applied life sciences. The search tool now provides a controlled vocabulary resource approaching 2.7 million descriptive terms.

CAB Thesaurus content has increased significantly since the 2016 edition. The updated version, with 2,651,201 terms, includes 166,395 distinct concepts (preferred terms) and 132,109 synonyms, as well as translations of these from English into ten European languages. These improvements make CAB Thesaurus the largest of its type in existence with at least twice the content of similar resources.


A number of important additions and revisions ensure the search tool remains relevant for various research applications. One of the biggest updates included adding another 800 taxonomic names of invasive plants in addition to the more than 2,000 names added in 2016. Similarly 600 medical terms were added to improve indexing of Global Health content with a focus on neoplasms, medicinal drugs, and metabolic markers related to disease. In total, over 14,700 new terms were added.
