****Apologies for possible cross-posting **** Dear all,

We are happy to remind you 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).

This is the *last Call for Papers*. You can find the details below. New elements to note:

1. *We're extending the submission deadline by one week, until September 8th!* 2. After the success of last year, we're re-opening the LChange Student Mentoring sessions! Interested students should send us a one-page research statement in relation to the topics of this workshop, and we will pair them with a senior researcher. This is not limited to authors who submit a paper to the workshop. Application deadline: October 10th 3. Via our sponsor, Iguanodon.ai, we can offer one free registration for a PhD student! More details below. Application deadline: October 10th. 4. Papers already submitted to EMNLP'23 can enter our fast-track submission process. You need to provide us with the reviews and your OpenReview paper ID. Submission deadline: October 8th.

============================================== 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 a 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. We hope to make this fourth edition another resounding success!

==Important Dates==

September 1, 2023: *Paper submission EXTENDED TO SEPTEMBER 8, 2023* October 6, 2023: Notification of acceptance October 18, 2023: Camera-ready papers due December 6, 2023: Workshop date

==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 https://2023.emnlp.org/calls/style-and-formatting/ (you can also directly use the Overleaf template https://www.overleaf.com/latex/templates/instructions-for-emnlp-2023-proceedings/scyjxmtnrskr), and the ACL submission policy https://www.aclweb.org/adminwiki/index.php?title=ACL_Policies_for_Submission,_Review_and_Citation .

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 model and dataset 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. ==Sponsor== We gratefully acknowledge the contribution of iguanodon.ai as gold sponsor.

Registration sponsorship:

Thanks to iguanodon.ai, we are sponsoring the registration fees for the EMNLP conference, including the yearly ACL membership fee, for several students and early-career researchers. We therefore would like to invite interested candidates to apply by email, by October 10th 23:59 CEST, to syrielle.montariol@gmail.com with the following information:

- Short CV - 500-word abstract about current research - Whether it would be your first xACL event - Whether you have an accepted paper at EMNLP 2023 (including workshops) - Confirmation of your “student” status if you are one

We particularly encourage sponsorship applications from diverse backgrounds and underrepresented groups in the NLP community.

==Workshop Topics==

This workshop explores state-of-the-art computational methodologies, theories, and digital text resources to explore 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 modeling 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 who develop and test computational methods for detecting semantic change and laws of semantic change; and those who 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 modeling 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 Task1 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== Mario Giulianelli, Institute for Logic, Language and Computation of the University of Amsterdam
