Terminology arises from the need to name objects and actions associated with the various facets of human activity.

Terminologists are professionals specializing in terminological research, which includes gathering, analyzing and recording information on one or more concepts. As part of ad hoc or thematic research, they identify terms designating concepts specific to a field of use or establish definitions to be associated with terms found in context.

They also define terms in use for businesses, databases, glossaries, dictionaries and lexicons for the purpose of standardization.

Terminologists are skilled in information technologies, demonstrate attention to detail, and enjoy conducting in-depth research. They also have a lively intellectual curiosity and an aptitude for synthesizing information. Due to their experience and professional relationships with specialists, terminologists often play an advisory role in the management of projects in their own fields.
