A controlled natural language (CNL) is based on natural language but comes with restrictions on 
vocabulary, grammar, and/or semantics. The general goal is to reduce or eliminate ambiguity and 
complexity.

Some of these languages are designed to improve communication among humans, especially for 
non-native speakers of the respective natural language. In other cases, the restrictions on the 
language are supposed to make it easier for computers to analyze such texts in order to improve 
computer-aided, semi-automatic, or automatic translations into other languages. A third group of 
CNL has the goal to enable reliable automated reasoning on seemingly natural texts.
Such languages have a direct mapping to some sort of formal logic and should improve the 
accessiblity of formal knowledge representations or specifications for people unfamiliar with 
formal notations.

All these types of CNL are covered by this workshop.

Important Dates
---------------

Submission deadline (extended):  6 April 2012
Notification of acceptance:      25 May 2012
Deadline for revised papers:     18 June 2012
Workshop:                        29-31 August 2012


Submissions and Proceedings
---------------------------

We invite researchers to submit papers with novel contributions in the area of CNL. These research 
papers should be formatted according to the Springer LNCS format and should not exceed 15 pages 
(but shorter papers are highly welcome too). Papers should be submitted in PDF format via the 
EasyChair conference system:

   http://www.easychair.org/conferences/?conf=cnl2012

Accepted papers will be included in the printed workshop proceedings to be published by Springer 
within the LNAI series. Authors of accepted papers will be invited to present their research at 
the workshop. Unlike the previous CNL workshops, the final papers will be reviewed and published 
before the workshop (there are no extended abstracts anymore).


Venue
-----

The workshop will take place at the Department of Informatics and the Institute of Computational 
Linguistics of the University of Zurich in Switzerland.
