Controlled languages

Controlled languages are natural languages that have in some way been altered to make them simpler, easier to use, or more acceptable to those who do not speak the original language well. Most of these have been based on English.

• Ander-Saxon (described in the article Anglo-Saxon linguistic purism)
• Basic English
• E-Prime
• Globish
• Plain English
• Simplified English
• Special English

Visual languages

Visual languages use symbols or movements in place of the spoken word.

• Blissymbols (zbl)
• Gestuno
• Signuno

Engineered languages

Human-usable

• An Essay towards a Real Character and a Philosophical Language by John Wilkins
• aUI
• Characteristica universalis
• Ilaksh
• Isotype
• Ithkuil
• Láadan (ldn)
• Loglan
• Logopandecteision
• Lojban (jbo)
• Ro
• Unilingua

Knowledge representation

See also: Ontology language

• Several wellknown Knowledge Query and Manipulation Languages have been created from extensive research projects, to represent and query knowledge on computers:
  • Knowledge Interchange Format (KIF), a precursor for knowledge representation.
  • Common Logic (CL), an ISO standard derived from KIF.
  • Resource Description Framework (RDF), a language standardized by the World Wide Web Consortium (W3C) based on the principles of Common Logic, which represents knowledge as a directed graph built from unordered sets of "sentences" (in fact, as relational triples: subject, relation, attribute) using a XML syntax for its interchange format. Each element of the triple can be either a simple value (if its semantic value is not specified outside of the relation using it), or identifiers of objects (such as URIs) that are part of enumeration built from another subset of relational triples. The relations may be open (in which case the attributes are not enumerable) or closed in a finite enumerable set whose elements can be easily represented as objects as well with their own identity participating in many different relations for other parts of the knowledge.
    • UML may be used to describe the sets of relations and rules of inference and processing, and SQL may be used to use them in concrete schemas and compact store formats, but RDF designs its own (semantically more powerful) schema language for handling large sets of knowledge data stored in RDF format.
    • RDF is probably useful only for automated machine processing, but its verbosity and complex (for a human) representation mechanisms and inference rules does not qualify it as a human language except in very limited contexts. It is still a specification with extensive research.
  • Web Ontology Language (OWL), another knowledge representation language standardized by W3C, and derived from Common Logic.
• CycL
• The Distributed Language Translation project used a "binary-coded" version of Esperanto as a pivot language between the source language and its translation.
• Lincos
• Loom
• Universal Networking Language (UNL)

Artistic languages

Languages used in fiction

Poul Anderson

• Angley, Unglish and Ingliss - three languages spoken respectively in Western Europe, North America and the Pacific in the 29th century world of Poul Anderson's Orion Shall Rise. All derived from present-day English, the three are mutually unintelligible, following 800 years of separate development after a 21st century nuclear war and the extensive absorption of words and grammatical forms from French in the first case, Russian, Chinese and Mongolian in the second, and Polynesian in the third.
• Anglic, the dominant language of the declining Galactic empire depicted in Poul Anderson's Dominic Flandry series, is descended from present-day English but so changed that only professional historians or linguists can understand English texts.
• Anglic: unrelated to the above, seen in the Civilization of the Five Galaxies in David Brin's Uplift Trilogies; is descended from modern English, modified to account for the differences in the culture on Earth and its colonies.
