Call for Papers: VarDial 2026 - The Thirteenth Workshop on NLP for Similar Languages, Varieties and Dialects

VarDial 2026: https://sites.google.com/view/vardial-2026/

VarDial 2026 will be colocated with EACL 2026 in Rabat, Morocco. We anticipate a discussion on computational methods and language resources for closely related languages, language varieties, and dialects.

We welcome papers dealing with one or more of the following topics:
- Language resources and tools for similar languages, varieties and dialects;
- Evaluation of language resources and tools applied to non-dominant language varieties;
- Cross-lingual transfer and adaptation of models to similar languages, varieties and dialects;
- Automatic identification of lexical variation;
- Automatic classification of language varieties;
- Machine translation between closely-related languages, language varieties and dialects;
- Corpus-driven studies in dialectology and language variation;
- Computational approaches to mutual intelligibility between dialects and similar languages;
- Text similarity and adaptation between language varieties;
- Linguistic issues in the adaptation of language resources and tools (e.g., cognate detection, semantic discrepancies, lexical gaps, false friends);
- Studies focusing on related creole languages and their lexifier languages;
- Studies focusing on diachronic language variation (e.g. phylogenetic methods, historical dialects).

In addition to the topics listed above, we also welcome papers dealing with diachronic language variation (e.g. phylogenetic methods, historical dialects).
