Seventh International Workshop on Controlled Natural Language (CNL 2020/21)

8/9 September 2021 — Amsterdam, Netherlands

Co-located with SEMANTiCS 2021

The proceedings are now available in the ACL Anthology

The workshop was originally planned for 2020 but was postponed to 2021 due to Covid-19. The workshop will be a hybrid one: online as well as physical participation will be possible.

This workshop on Controlled Natural Language (CNL) has a broad scope and embraces all approaches that are based on natural language and apply restrictions on vocabulary, grammar, and/or semantics. This includes (but is certainly not limited to) approaches that have been called simplified language, plain language, formalized language, processable language, fragments of language, phraseologies, conceptual authoring, language generation, and guided natural language interfaces.

Some CNLs 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 and formal knowledge representation from seemingly natural texts. All these types of CNL are covered by this workshop.

Important Dates

Venue and Registration

The workshop will be at the Meervaart Theatre in Amsterdam, together with the SEMANTiCS conference. Online as well as physical participation will be possible.

You can register via the SEMANTiCS registration system. To attend both CNL workshop days, you will need to minimally purchase two single day tickets (either online or onsite). The 4-day pass also includes the workshop days. We hope that most participants will choose to attend both workshop days, but registering for only one of the days is also possible.


Possible topics for CNL 2020/21 include:

Submissions and Proceedings
