Language resource management -- Controlled natural language (CNL) -- Part 1: Basic concepts and principles
As part of a drive to provide international standards for language resource management, ISO/TS 24620-1:2015 on controlled natural language (CNL) sets out the principles of CNL and its utilization together with the relevant supporting technology. However, ISO/TS 24620-1:2015 also aims to introduce a general view of CNL with its objectives and characteristics and provide a scheme for classifying a range of CNLs. ISO/TS 24620-1:2015 additionally specifies certain normalizing principles of CNLs that control the use of natural languages in particular domains and are also oriented towards areas of practical application. These areas include public administrative communications, search optimization, and the management of automatic question-answering systems, but the current version of ISO/TStract 24620-1:2015 does not address any issue involving these applications directly.

Upravljanje z jezikovnimi viri - Nadzorovani naravni jezik (CNL) - 1. del: Osnovni pojmi in načela
Kot del težnje k zagotavljanju mednarodnih standardov za upravljanje z jezikovnimi viri ta del standarda ISO 24620 o nadzorovanem naravnem jeziku (CNL) določa načela nadzorovanega naravnega jezika in njegove uporabe skupaj z zadevno podporno tehnologijo. Cilj tega dela standarda ISO 24620 je tudi predstavitev splošnega pogleda na nadzorovani naravni jezik z njegovimi cilji in lastnostmi ter podajanje sheme za razvrstitev različnih nadzorovanih naravnih jezikov.
Poleg tega ta del standarda ISO 24620 določa tudi nekatera načela normalizacije nadzorovanih naravnih jezikov, ki nadzorujejo uporabo naravnih jezikov v posebnih domenah in se usmerjajo tudi na področja praktične uporabe.
Ta področja vključujejo javno upravno komuniciranje, optimizacijo iskanja in upravljanje samodejnih sistemov za vprašanja in odgovore, vendar pa trenutna različica tega dela standarda ISO 24620 ne obravnava nobenih vprašanj, ki se neposredno nanašajo na te načine uporabe.

ISO 24620 consists of the following parts, under the general title Language resource management —
Controlled natural language (CNL):
— Part 1: Basic concepts and principles
iv © ISO 2015 – All rights reserved
Introduction
The long history of the study of controlled natural language (CNL) has proved its effectiveness
especially in technical documentation, technical communication, and business communication. In time,
CNL has come to be applied in different ways in such fields as information management, librarianship,
terminology management, and legal documents. Its commercial impact was established in the 1990s due
to its effectiveness in information and communication technology applications like machine translation
and mobile communication. Moreover, ‘text simplification’, a major task of CNL, promotes efficient
communication with regard to all kinds of language use on the web. An example of this is the simplified
English Wikipedia.
This part of ISO 24620 aims both to define major concepts related to CNL and to outline the scope of CNL
and its various applications in relation to language resource management. These include the following:
a) the pre-editing of texts for CNL in preparation for machine translation;
b) the development of new or the re-use of existing controlled vocabularies for CNL;
c) the structuring and harmonization of content for content management;
d) technical writing including the formulation of standards;
e) facilitating communication with and for persons with disabilities (PWD), for instance, in ambient
assisted living (AAL) or augmentative and alternative communication (AAC).
In this connection, special attention is given to aspects of interoperability: from technical interoperability
through semantic interoperability to content interoperability. As a Technical Specification (TS), this
part of ISO 24620 identifies the following:
— the environments of CNL used for the purposes and applications of all kinds (e.g. computer-assisted
technical writing);
— the relationships to language resource management and related systems;
— the potential for new applications (e.g. in the processes, whether manual or automatic, of knowledge
acquisition and knowledge fusion based on and linked to the web).
This part of ISO 24620 is the first in a planned series of International Standards on CNL. Subsequent
parts will focus on issues specific to particular viewpoints and/or applications such as particular CNLs,
CNL interfaces, the implementation of CNLs, and evaluation techniques for CNL.

(2.3)] to read a text (2.21) and to improve the computational processing of a text.
Note 2 to entry: CNL is an engineered (i.e. constructed) language that is based on a particular natural language,
but is more restrictive as regards lexicon, syntax, or semantics, while at the same time preserving most of its
natural properties. Here, CNL is a countable noun.

Part 1:
Basic concepts and principles
1 Scope
As part of a drive to provide international standards for language resource management, this part of
ISO 24620 on controlled natural language (CNL) sets out the principles of CNL and its utilization together
with the relevant supporting technology. However, this part of ISO 24620 also aims to introduce a general
view of CNL with its objectives and characteristics and provide a scheme for classifying a range of CNLs.
This part of ISO 24620 additionally specifies certain normalizing principles of CNLs that control the use
of natural languages in particular domains and are also oriented towards areas of practical application.
These areas include public administrative communications, search optimization, and the management
of automatic question-answering systems, but the current version of this part of ISO 24620 does not
address any issue involving these applications directly.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1

language (2.11) that has been specifically devised for some applications
Note 1 to entry: The grammar of an artificial language is formulated systematically for some specific purposes of
its used in practical applications especially in the area of human or human-machine communications.
2.2
authoring
writing a document such as a report, manual, article, or book
2.3

understanding the content (2.4) of a document
2.4
content
information content
information contained in or conveyed by a language (2.11), which can be in a written, spoken, or some
other forms such as images
2.5
content management
controlling the content (2.4) of a text (2.21) or the media in general
while analysing or revising it
Note 1 to entry: This includes version control of revised documents, contents in versions of similar documents,
and the management of relations between items in a document.
2.6
controlled natural language
controlled language
CNL
subset of natural languages (2.12) whose grammars and dictionaries have been restricted in order to
reduce or eliminate both ambiguity and complexity
Note 1 to entry: As a generic, CNL is an uncountable noun that refers to the abstract properties of all controlled
natural languages and not to a particular natural language or application for a specific purpose. It is engineered
(i.e. constructed) with a view to reducing or eliminating ambiguity and complexity and aims both to make it
easier for human readers [particularly non-native users, non-experts, and people with limited comprehension
(2.3)] to read a text (2.21) and to improve the computational processing of a text.
Note 2 to entry: CNL is an engineered (i.e. constructed) language that is based on a particular natural language,
but is more restrictive as regards lexicon, syntax, or semantics, while at the same time preserving most of its
natural properties. Here, CNL is a countable noun.

controlled vocabulary
CV

Note 2 to entry: Most controlled vocabularies target a specific, narrow domain. Unlike CNL, they do not deal with

approaches, especially domain-specific ones, include controlled vocabularies.
