This workshop on practical and theoretical aspects of CG will be co-located with NoDaLiDa 2023 in Thórshavn. The new edition of the workshop continues the tradition of CG workshops at NoDaLiDa, which started in 2005. Apart from the traditional field of corpus-oriented tagging and parsing, Constraint Grammar continues to inspire applicational work, providing a robust NLP backbone in end user-oriented systems in various areas of language technology, such as spell and grammar checking, comma correction, ICALL, machine translation, lexicography and others. We therefore envision workshop contributions both regarding basic grammatical research and corpus linguistics on the one hand, and CG-based applications on the other hand.

Constraint Grammar has always elicited a strong interest from researchers working on less-resourced languages, such as the Sami languages, Greenlandic, Faroese, Tibetan and the Celtic languages, for which we explicitly invite both finished and ongoing work.

Finally, there will be room for methodological contributions on the CG formalism itself regarding either its expressive power or improvements in compiler implementation.

Call for abstracts

We invite contributions concerning CG grammars for various languages or CG systems used in tools and applications. Research reports from fields relevant to the CG framework on the input side - such as finite-state analyzers, ontologies etc. - are also welcome. Finally, we are hoping for methodological contributions and experiments exploiting advances in expressive power in the most widely used CG compiler, CG-3. As usual, we encourage short papers on ongoing work.

The workshop will be organized as a half-day workshop with both full and short papers. Contributions will be reviewed anonymously, and the papers will be published in the NoDaLiDa 2023 workshop proceedings.

We invite extended abstracts, approximately 1500 words (for an 8 page full paper) or 750 words (for a 4 page short paper) - additional pages with bibliographic references not included.
