'''Natural-language user interface''' ('''LUI''' or '''NLUI''') is a type of [[User interface|computer human interface]] where linguistic phenomena such as verbs, phrases and clauses act as UI controls for creating, selecting and modifying data in software applications.

*[[SHRDLU]], a natural-language interface that manipulates blocks in a virtual "blocks world"

*''Lunar'', a natural-language interface to a database containing chemical analyses of [[Apollo- 11]] moon[[Moon rocks]] by [http://parsecraft.com/ William A. Woods].

*''Chat-80'' transformed English questions into [[Prolog]] expressions, which were evaluated against the Prolog database. The code of Chat-80 was circulated widely, and formed the basis of several other experimental Nl interfaces. An online demo is available on the LPA website.<ref>{{cite web|url=http://www.lpa.co.uk/pws_dem5.htm|title=Chat-80 demo|access-date=29 January 2018|archive-url=https://web.archive.org/web/20161111194841/http://www.lpa.co.uk/pws_dem5.htm|archive-date=11 November 2016|url-status=dead|df=dmy-all}}</ref>

*[[ELIZA]], written at MIT by Joseph Weizenbaum between 1964 and 1966, mimicked a psychotherapist and was operated by processing users' responses to scripts. Using almost no information about human thought or emotion, the DOCTOR script sometimes provided a startlingly human-like interaction. An online demo is available on the LPA website.<ref>{{cite web|url=http://www.lpa.co.uk/pws_dem4.htm|title=ELIZA demo|access-date=29 January 2018|archive-url=https://web.archive.org/web/20161126102154/http://www.lpa.co.uk/pws_dem4.htm|archive-date=26 November 2016|url-status=dead|df=dmy-all}}</ref>

{{main|Wolfram Alpha}}

Wolfram Alpha is an online service that answers factual queries directly by computing the answer from structured data, rather than providing a list of documents or web pages that might contain the answer as a [[search engine]] would.<ref>{{cite news |url=https://www.theguardian.com/technology/2009/mar/09/search-engine-google |title=British search engine 'could rival Google' |last=Johnson |first=Bobbie |date=2009-03-09 |work=[[The Guardian]] |access-date=2009-03-09}}</ref> It was announced in March 2009 by [[Stephen Wolfram]], and was released to the public on May 15, 2009.<ref name="launch date">{{cite web|url=httphttps://blog.wolframalpha.com/2009/05/08/so-much-for-a-quiet-launch/ |title=So Much for A Quiet Launch |publisher=Wolfram Alpha Blog |date=2009-05-08 |access-date=2009-10-20}}</ref>

===Others===

* [[Ask.com]] – The original idea behind Ask Jeeves (Ask.com) was traditional keyword searching with an ability to get answers to questions posed in everyday, natural language. The current Ask.com still supports this, with added support for math, dictionary, and conversion questions.

* [[Braina]]<ref>{{cite web|url=httphttps://www.brainasoft.com/braina/|title=Braina - Artificial Intelligence Software for Windows|website=www.brainasoft.com|access-date=29 January 2018}}</ref> – Braina is a natural language interface for [[Windows OS]] that allows to type or speak English language sentences to perform a certain action or find information.

[[File:GNOME Do Classic.png|thumb|Screenshot of GNOME DO classic interface.]]

* [[GNOME Do]] – Allows for quick finding miscellaneous artifacts of GNOME environment (applications, Evolution and Pidgin contacts, Firefox bookmarks, Rhythmbox artists and albums, and so on) and execute the basic actions on them (launch, open, email, chat, play, etc.).<ref>Ubuntu 10.04 Add/Remove Applications description for GNOME Do</ref>

* [[hakia]] – hakia was an Internet search engine. The company invented an alternative new infrastructure to indexing that used SemanticRank algorithm, a solution mix from the disciplines of ontological semantics, fuzzy logic, computational linguistics, and mathematics. hakia closed in 2014.
