Instructions for CLEF 2022 Working Notes in the CEUR-WS Proceedings

As usual, the CLEF 2022 Labs working notes will be published in the proceedings. The electronic Working Notes will be organised according to the Labs. If one group participates in more than one Lab, separate reports are to be submitted. Moreover, for those Labs that are subdivided within several tasks, separate reports for different tasks are to be provided.

Paper Submission

Please, notice that we will use the metadata of the Easychair submission when preparing the final Working Notes. So pay attention to input authors, title and affiliations correctly.

The paper submission has to be done electronically through EasyChair, through the following link:

Using EasyChair for Paper Submission

  1. Authors must log in using their own username and password. If you don't already have an Easychair account, you will find the instructions to obtain one on the same page.
  2. Once you have logged in, click on New Submission, select the correct Lab/Track and Group/Task and then follow the instructions to submit your paper.

When logging into EasyChair, the authors will find a separate Easychair Track for each CLEF Lab as in the figure below.

Select the track corresponding to your Lab

Afterwards, in the paper upload form, after the keywords, authors will find a checklist with the "Submission Topics" corresponding to the different tasks in that Lab. Please mark those which correspond to your paper:

Mark the topic corresponding to the lab tasks which are described in your paper.

For each task to which a group participated, groups are requested to submit a report describing their experiments. In the CEUR-WS working notes, there can be either a single paper for all the tasks to which a group participated or separated papers for each task. The decision on what is the most appropriate way to proceed for a given lab is up to the lab organizers.

After the review process, if the paper gets accepted, authors will be requested to submit the camera-ready version, following the reviewers’ recommendations. For each camera-ready submission, three items are required:

  • - A ZIP file containing all the submission source files
  • - A PDF file of the submission (with no page headers/footers/page numbers)
  • - A PDF file with the scanned and signed copyright agreement (otherwise, the submission will not be published in the final working notes).


Please remember that the strict deadlines for receiving the electronic versions of all papers are:

  1. Working Notes Papers due 27 May 2022.
  2. CEUR-WS Camera Ready Working Notes Papers due 1 July 2022.
    This is a STRICT DEADLINE.

All the deadlines are MIDNIGHT CEST.

Copyright Form

It is mandatory to print the copyright form, to sign it by hand, and to upload a scan version of the signed hard copy of the copyright form.

When uploading the camera-ready version of the accepted papers, a scanned and signed CLEF version of the CEUR copyright form must be uploaded along the source and the PDF files of the submission (otherwise the submission will not be published in the final working notes).

The copyright form can be downloaded here: 1pqwL_1zdANJsKqSRUx5_EIouQpEkHake/view?usp= sharing

When filling the copyright form:

  • - Report the name of the contribution as indicated in the original manuscript and on the Easychair platform.
  • - Report the complete list of all the authors, including the corresponding author. Names need to be identical to the ones reported in the original manuscript, and also in the same order.
  • - Indicate additional information only for the corresponding author.

Guidelines to prepare reports for the CLEF 2022 Working Notes

The working note papers are technical reports written in English and describing the participating systems and the conducted experiments. They should provide, at least, the following information:

  1. Title
  2. Authors
  3. Affiliations
  4. Email addresses of all authors
  5. Text body. This should contain information on:
    • - tasks addressed
    • - main objectives of experiments
    • - approach(es) used and progress beyond the state of the art
    • - resources employed
    • - results obtained
    • - analysis of the results  
    • - perspectives for future work  

The papers must be formatted according to CEUR-WS template available at either using the Word or the Latex one column template.

MAX LENGTH: no upper page limit is set, as papers are published only electronically, but experience teaches the overwhelmingly long papers are not effective.

If you need to refer to the LNCS proceedings or to the Working Notes as a whole, here is the information about them:
