Seventh International Workshop on Controlled Natural Language (CNL 2020)

postponed to September 2021 — Amsterdam, Netherlands

Co-located with SEMANTiCS 2020

⚠️ Due to Covid-19, the workshop is postponed to 2021! ⚠️

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

Postponed to 2021.
