Call for Papers

Submission Deadline: extended to 27 March 2023; final extension: 31 March 2023

We invite submissions to the fourth biennial conference on Language, Data and Knowledge (LDK 2023) to be held in Vienna, Austria in September 2023. This conference aims to bring together researchers from across different disciplines concerned with the acquisition, treatment, curation and use of language data in the context of data science and knowledge-based applications. This edition builds upon the success of the inaugural event held in Galway, Ireland in 2017, the second LDK in Leipzig, Germany in 2019, and the third LDK in Zaragoza, Spain in 2021.

Invited Speakers

We are happy to announce Diana Maynard (University of Sheffield), Ruben Verborgh (Ghent University), and Ruth Wodak (Lancaster University/University of Vienna), as keynote speakers for LDK 2023.

Paper Submission

We welcome submissions of relevance to the topics listed below. Submissions can be in the form of:

  • Long papers: 9–12 pages;
  • Short papers: 4-6 pages.

All submission lengths are given including references. Accepted submissions will be published in an open-access conference proceedings volume, free of charge for authors, and included in the ACL Anthology. The ACL templates should therefore be used for all conference submissions.

As the reviewing process is single-blind, submissions should not be anonymised.

Papers should be submitted via OpenReview at the following address:

All articles must represent original work: when submitted, the submission must not have been previously published*, and the material in it must not have been/be submitted for review at another journal or conference while under review at LDK 2023. 

*This excludes papers on preprint archives, such as arXiv, which we do not consider to have been previously published.

The conference will be hybrid (face-to-face and remote). Note that at least one author of each accepted paper must register to present the paper at the conference (either remotely or on-site). There will be no registration fee administered for participating in LDK 2023.

Presentation format

Accepted submissions will be selected for oral or poster presentation based on recommendations from the reviewers. This decision will not reflect any difference in the quality of the papers, and there will be no distinction between oral and poster presentations in the published proceedings. Authors of accepted short papers or posters are welcome to present their work as a demo in addition to the regular presentation.
