Working Notes

Participant working notes will be published in the CEUR-WS Working Notes of CLEF 2026. All submissions, reviews, and camera-ready versions are handled through EasyChair: https://easychair.org/conferences/?conf=clef2026

Short System Description

After result publication, participants who have chosen to publish their results and proceed with a working notes paper are kindly asked to send us a short system description by Thursday 28 May 2026.

The description should be a single paragraph of about 12–15 lines formatted using the CEUR-WS one-column template (see Formatting section below), and submitted by email to the organizers at the address used for your run submission.

We will use these descriptions when writing the HIPE overview paper to summarise participating approaches.

Paper Content

Working notes are technical reports written in English describing your system and experiments. Papers should include at minimum:

  • Title, authors, affiliations, and email addresses of all authors
  • Body of text covering:
    • Tasks performed
    • Main objectives of the experiments
    • Approach(es) used and progress beyond baselines or state of the art
    • Resources employed
    • Results obtained — please report on test sets, and on dev sets where appropriate. Note that the organizers’ overview paper will focus on the best run per team; your paper may report on individual runs in more detail.
    • Analysis and discussion of results
    • Perspectives for future work

In the interest of reproducibility, we encourage you — whenever possible — to publish:

  • your code on a public repository with an associated licence
  • any additional resources you may have used

Formatting

Papers must be formatted using the CEUR-WS one-column template available here.

Maximum length: No strict upper limit, as papers are published electronically only. We recommend 6–10 pages excluding references. Concise, focused papers are more effective.

Submission and Review

Submit your paper electronically via EasyChair: https://easychair.org/conferences/?conf=clef2026

After logging in, select the HIPE track and follow the instructions.

Important: The metadata entered in EasyChair will be used for the final working notes. Please ensure that the following information is correct and matches the PDF of your paper:

  • Complete and correctly spelled author names
  • Authors listed in the correct order
  • Correct paper title

Review Process

Reviews will be conducted by the organizing team, with the objective of ensuring paper quality. Unless there are significant shortcomings, all submitted papers are expected to be accepted and published in the working notes.

Publication and Cross-References

Post-Publication Changes

Once the CEUR-WS Working Notes are published, they cannot be modified — including PDFs, titles, or author names. A short pre-publication checking phase (21–25 July 2026) will allow authors and organizers to catch any errors in the table of contents before final publication. Please make sure all submitted materials are complete and correct by the camera-ready deadline.

Cross-references between the HIPE Overview Paper and Participant Working Notes Papers

Shared task organisers will publish two overview papers: 1) a condensed overview in the CLEF 2026 LNCS proceedings, and 2) an extended overview in the CEUR-WS Working Notes proceedings.

Participant teams will publish working notes papers in the CEUR-WS Working Notes proceedings.

Shared task organisers will cite participant papers in both overviews, and participants are encouraged to cite the HIPE extended overview in their working notes papers. The overview papers will present the task, include a brief summary of each participant’s approach, present the results and the main findings.
