A growing number of areas witness the current trend of automation, robotization and artificial intelligence (AI). Therefore, converting information into a form that can be understood by machines is of utmost importance in the future. These three technological advancements require the precise description of languages, consequently, the systematic description of the features of specialized languages is one of the current tasks of linguistics.
