*A one-day workshop on Computational Linguistics on East Asian Languages* will be held as an online event on 31 July 2022, in conjunction with the 29th International Conference on Head-driven Phrase Structure Grammar (29-30 July 2022). The aim of the workshop is to promote interdisciplinary and cross-language discussion on approaches to linguistic analyses using computational techniques (broadly construed), with a focus on East Asian languages. We strongly encourage researchers from outside the HPSG framework to submit. Possible topics include, but are not limited to syntactic/semantic parsing, cognitive modelling with computational models, development of language resources with annotations beyond the word level (treebanks, propbanks, discourse annotations, etc.), and applications of large-scale corpus data and/or sophisticated machine learning techniques to addressing questions in linguistic theory. *Workshop Format: * The workshop on Computational Linguistics on East Asian languages will take place following the two-day main HPSG 2022 conference. Presentations will be pre-recorded and pre-loaded on the conference website, and the discussion period will be online. *Invited speaker:* Koji Mineshima (Keio University) *Submissions: *We welcome two types of submissions for the workshop: - Long papers (4-page abstract + 1 page data, figures & references; 20 minute pre-recorded presentation + 15 minute online discussion) - Short papers (2-page abstract + 1 page data, figures & references; 10 minute pre-recorded presentation + 10 minute online discussion) Please note that abstracts submitted for the “long paper” track can be accepted as “short papers” (and vice versa) and that the Program Committee may choose to move a paper submitted to the workshop to the main conference (and vice versa), whenever such decisions seem appropriate. Only “long papers” will appear in the proceedings. If you intend to present at the workshop, please choose the option Computational Linguistics Workshop as your Submission Type. All abstracts should be submitted in PDF format via: https://easychair.org/conferences/?conf=hpsg22 All abstracts will be reviewed anonymously by at least two reviewers. The submissions should not include the authors' names, and authors are asked to avoid self-references. Please direct any questions to the Program Committee Chair: Elodie Winckel (hpsg22@easychair.org). *Workshop organizer: * Yusuke Kubota (National Institute for Japanese Language and Linguistics) *Important dates:* Abstract submission deadline: March 16th 2022 (anywhere on Earth) Notifications of acceptance: May 2nd 2022 Main Conference: July 29th-30th 2022 Workshop on Computational Linguistics on East Asian Languages : July 31st 2022 *Publication:* A call for contributions to the proceedings will be issued after the conference. The papers will be published either at the online proceedings platform at CSLI together with the main conference proceedings or in a separate collective volume.
