Lexicon

A lexicon usually refers to the specific vocabulary of a specific occupation or area of study although technically it can refer to the vocabulary of any group of people. Various organizations have projects similar to RadLex which have sought to codify and standardize the lexicon of radiologists or groups of them e.g. BIRADS has a lexicon specific to mammography.

Practically speaking explicit and uniform lexicons facilitate communication among professionals and are a key element in natural language processing programs.
