Editing Sublanguage (section)

==In natural language==

In [[Informatics (academic field)|informatics]], [[natural language processing]], and [[machine translation]], a sublanguage is the language of a restricted domain, particularly a technical domain. In mathematical terms, "a subset of the sentences of a language forms a sublanguage of that language if it is closed under some operations of the language: e.g., if when two members of a subset are operated on, as by ''and'' or ''because'', the resultant is also a member of that subset".<ref>{{cite book |last1=Harris |first1=Zellig |title=Language and Information |date=1988 |publisher=Columbia University Press |location=New York}}</ref><ref>{{cite book |last1=Kittredge |first1=Richard |last2=Lehrberger |first2=John |title=Sublanguage: Studies of language in restricted semantic domains |date=1982 |publisher=Walter de Gruyter |location=Berlin}}</ref><ref>{{cite book |last1=Sager |first1=Naomi |last2=Nhàn |first2=Ngô Thanh |editor1-last=Nevin |editor1-first=Bruce E |editor2-last=Johnson |editor2-first=Stephen M |title=The Legacy of Zellig Harris |date=2002 |publisher=John Benjamins |location=Amsterdam/Philadelphia |pages=79–120 |url=https://cs.nyu.edu/sager/Computability_2002.pdf |accessdate=22 September 2020 |chapter=The computability of strings, transformations, and sublanguage}}</ref> This is a specific term for what in most linguistic study is referred to a language variety or register.<ref>{{cite journal |last1=Karlgren |first1=Jussi |title=Sublanguages and Registers – A Note On Terminology |journal=Interacting with Computers |date=1993 |volume=5 |issue=3 |pages=348–350 |doi=10.1016/0953-5438(93)90015-L |url=http://eprints.sics.se/54/1/registerIWCrevised.pdf |accessdate=22 September 2020}}</ref>
