Publishing Instructions

You have received the reviews of your accepted paper by email. Please carefully consider them as you prepare the camera-ready version for the proceedings. You also need to prepare the following six items. Details for each of them are provided below.

1. Final paper: The camera-ready version of your paper, which will be published in the Springer proceedings.
2. Alternative text (alt text): An alt text description for each figure in your manuscript.
3. Springer consent-to-publish form: The completed and signed consent-to-publish form.
4. ArXiv version: An ArXiv version of your paper, which will be used to create the Sofsem conference index on arXiv.
5. Author information file: A plain text file containing your paper’s arXiv identifier.
6. Registration: Complete your conference registration in accordance with the registration requirements and deadlines below.

1. Final paper

Please submit the files belonging to the camera-ready version of your paper using your EasyChair author account. You need to change your role to "Proceedings author." Follow the instructions after the login for uploading two files:

1. a zipped file containing all your LaTeX sources, a plain text file called "info.txt", and an excel sheet called "AltTextForFIgure.xlsx" (see below), and
2. a PDF version of your camera-ready paper.

No material can be added to or moved from the appendix to the paper, unless required by a reviewer. A paper must adhere to a strict limit of 17 pages including everything and must not have more pages than the version (including references, excluding appendix) submitted to the reviewing process. 

Exceptions must be discussed beforehand with the PC co-chairs (sofsem2027@easychair.org). No appendix should be included in the camera-ready paper (but it is encouraged to be included in the arXiv version, see below).

Please follow strictly the author instructions of Springer-Verlag when preparing the final version. In particular:

1. no page numbers should appear in your paper,
2. no modifications of the standard margins and fonts (e.g., by using packages times or mathptmx or \vspaces) are allowed,
3. ensure that affiliations and bibliography conform to Springer’s style requirements,
4. indicate a corresponding author, otherwise Springer will, by default, mark the author who signed the copyright form,
5. include an OrcID, if you already have one, for each author.

PROOF READING: Once data processing is finished, the publisher will contact all corresponding authors and ask them to check their papers. We expect this to happen shortly before the printing of the proceedings. At that time, your quick interaction with Springer-Verlag will be greatly appreciated.

2. Alternative text (alt text)

In accordance with the EU Accessibility Act, Springer requires that the SOFSEM proceedings be fully accessible to all readers. Consequently, all papers included in the proceedings must comply with the Web Content Accessibility Guidelines (WCAG).

Under these guidelines, non-text elements—such as figures, illustrations, and tables provided as images—must be accompanied by textual alternatives, commonly referred to as alternative text or Alt Text.

Please provide an Alt Text entry for each figure in your manuscript using this Excel file. For every figure, indicate its label as it appears in the PDF (e.g., Fig. 1, Fig. 2(a), etc.) along with the corresponding Alt Text.  Submit this file as part of the zip-file that you upload to EasyChair.

3. Copyright

Please upload a signed and completed consent-to-publish form to EasyChair. The Springer form can be found here. It is sufficient for one of the authors to physically sign the form. Digital signatures are not accepted by Springer. Please upload the signed form in PDF format to easyChair.

4. Arxiv proceedings

In order to provide immediate and unrestricted open access to the published papers, we will publish an open access arXiv conference index containing links to self-archived versions of the final versions of all accepted papers. Thus, you must submit the camera-ready version of your paper to arXiv. More details:

• To start a new submission, one author must be a registered user of the arXiv repository (https://arxiv.org). Instructions and FAQ for submitting new papers are found at https://arxiv.org/help/submit.
• Your arXiv submission (without appendix) should be identical to the final paper to be published in the LNCS proceedings except, possibly, for cross-references between the two versions (e.g. "details of the proof can be found in the full version [reference to arXiv]" vs. "details of the proof are in the appendix").
• In the arXiv submission, you are encouraged to include a *clearly marked appendix* that contains omitted material. This will not be part of the LNCS proceedings.
• When entering the meta-data for your arXiv submission, please use the following text in the Comment-field: "Appears in the Proceedings of the 52nd International Conference on Current Trends in Theory and Practice of Computer Science (Sofsem 2027)"

ArXiv offers a functionality called "arXiv replacement" that allows one to replace a previous version of a paper with a new version. You must send us the link to the version that is identical to the LNCS proceeding. This version can be a replacement of some older arXiv. Or vice versa, you can replace the LNCS proceedings version immediately with some other version that you like better (e.g., due to formatting or content). Notice that the latest updated version will be the easiest accessible from the web, e.g., from DBLP. However, the Sofsem 2027 index will link the proceedings-like version only.

Please note that arXiv submissions are sometimes put "on hold" (which may take multiple days to resolve), and even if not, they take at least one day to get approved. You must start the arXiv submission well in advance, November 26th at the latest, and are strongly encouraged to start it much earlier than that.

5. Author information file

Please create a plain text file called info.txt based on the following template:

The arXiv version for paper #XX can be found under
https://arxiv.org/abs/YYYY.ZZZZZv1

Please change the arXiv-link to reflect your long-paper version. Include the version number, even if there was only one version. 

Submit this file as part of the zip-file that you upload to EasyChair.

6. Registration

According to the call for papers, at least one author of each accepted paper is required to present the paper at the conference. Also, an individual registration is required for each accepted paper. When completing the registration form, please indicate which paper your registration is for. Early registration closes on January 11, 2027.

The registration form will become available soon.
