Dear all,

We are happy to remind that there will be a full-day workshop on computational approaches to historical language change (LChange’23) co-located with EMNLP (December 6-10, 2023).

The Second Call for Papers is below. The main updates compared to the 1st CfP are:

1. The submission page is now up and running at https://openreview.net/group?id=EMNLP/2023/Workshop/LChange 2. To encourage resource sharing at the reviewing phase, model and dataset papers do not need to be anonymous. The reviewing for the papers of this type will thus be single-blind.

======================================== 4th International Workshop on Computational Approaches to Historical Language Change 2023 (LChange’23) ========================================

Website: https://www.changeiskey.org/event/2023-emnlp-lchange/ Date: Dec 6, 2023 Location: Singapore and online Contact email: lchange2023@changeiskey.org

LChange'23 is the fourth workshop for computational approaches to historical language change with the focus on digital text corpora. Come join us for this exciting adventure!

The workshop builds upon its first iteration in 2019 (https://languagechange.org/events/2019-acl-lcworkshop/), and the subsequent events (2021, 2022). LChange'19 resulted in a book on Computational approaches to semantic change (https://langsci-press.org/catalog/book/303).

This year, LChange will be colocated with EMNLP 2023 in Singapore, as a hybrid event. The workshop will take place on Wednesday 6 December 2023. The main topic of the workshop remains the same: all aspects around computational approaches to historical language change with the focus on digital text corpora. We hope to make this fourth edition another resounding success!

==Workshop Topics==

This workshop explores state-of-the-art computational methodologies, theories and digital text resources on exploring the time-varying nature of human language.

The aim of this workshop is three-fold. First, we want to provide pioneering researchers who work on computational methods, evaluation, and large-scale modelling of language change an outlet for disseminating cutting-edge research on topics concerning language change. We want to utilize this workshop as a platform for sharing state-of-the-art research progress in this fundamental domain of natural language research.

Second, in doing so we want to bring together domain experts across disciplines by connecting researchers in historical linguistics with those that develop and test computational methods for detecting semantic change and laws of semantic change; and those that need knowledge (of the occurrence and shape) of language change, for example, in digital humanities and computational social sciences where text mining is applied to diachronic corpora subject to e.g., lexical semantic change.

Third, the detection and modelling of language change using diachronic text and text mining raise fundamental theoretical and methodological challenges for future research.

Besides these goals, this workshop will also support discussion on the evaluation of computational methodologies for uncovering language change. SemEval2020 Task 1 on unsupervised detection of lexical semantic change attracted three figure submission numbers and a total of 21 submitted system papers. Since then, three more tasks have been completed in Italian, Russian, and Spanish.

We invite original research papers from a wide range of topics, including but not limited to:

- Novel methods for detecting diachronic semantic change and lexical replacement - Automatic discovery and quantitative evaluation of laws of language change - Computational theories and generative models of language change - Sense-aware (semantic) change analysis - Diachronic word sense disambiguation - Novel methods for diachronic analysis of low-resource languages - Novel methods for diachronic linguistic data visualization - Novel applications and implications of language change detection - Quantification of sociocultural influences on language change - Cross-linguistic, phylogenetic, and developmental approaches to language change - Novel datasets for cross-linguistic and diachronic analyses of language

==Keynote Talks== To be announced. If you have any good suggestions, or anyone you would like to listen to, please contact us.

==Submissions== URL for submissions: https://openreview.net/group?id=EMNLP/2023/Workshop/LChange.

We accept two types of submissions, long and short papers, following the EMNLP 2023 style (you can also directly use the Overleaf template), and the ACL submission policy: * https://2023.emnlp.org/calls/style-and-formatting/ * https://www.overleaf.com/latex/templates/instructions-for-emnlp-2023-proceed... * https://www.aclweb.org/adminwiki/index.php?title=ACL_Policies_for_Submission...

Long and short papers may consist of up to eight (8) and four (4) pages of content, respectively, plus unlimited references; final versions will be given one additional page of content so that reviewers' comments can be taken into account.

LChange’23 also welcomes papers focusing on releasing a dataset or a model; these papers fall into the short paper category. To encourage resource sharing at the reviewing phase, model and dataset papers do not need to be anonymous.

Accepted papers will be presented orally or as posters and included in the workshop proceedings. Submissions are open to all, and are to be submitted anonymously. All papers will be refereed through a double-blind peer review process by at least three reviewers with final acceptance decisions made by the workshop organizers.

==Contact== Contact us if you have any questions: lchange2023@changeiskey.org

Organizers: Nina Tahmasebi, Syrielle Montariol, Haim Dubossarsky, Andrey Kutuzov, Simon Hengchen, David Alfter, Francesco Periti, and Pierluigi Cassotti.

If you have published in the field previously, and are interested in helping out in the PC to review papers, send us an email.

==Anti-Harassment Policy==

Our workshop highly values the open exchange of ideas, the freedom of thought and expression, and respectful scientific debate. We support and uphold the ACL Anti-Harassment policy (https://www.aclweb.org/adminwiki/index.php?title=Anti-Harassment_Policy), and any workshop participant should feel free to contact any of the workshop organizers or acl@aclweb.org, in case of any issues.
