CLEF 2026

Conference and Labs of the Evaluation Forum

Jena, Germany, September 21-24, 2026

  Call for Lab Proposals


    Background

The CLEF Initiative <http://www.clef-initiative.eu/>is a self-organised 
body whose main mission is to promote research, innovation, and 
development of information access systems with an emphasis on 
multilingual information in different modalities - including text and 
multimedia - with various levels of structure. CLEF promotes research 
and development by providing an infrastructure for:

 1.

    Independent evaluation of information access systems

 2.

    Investigation of the use of unstructured, semi-structured,
    highly-structured, and semantically enriched data in information access

 3.

    Creation of reusable test collections for benchmarking

 4.

    Exploration of new evaluation methodologies and innovative ways of
    using experimental data

 5.

    Discussion of results, comparison of approaches, exchange of ideas,
    and transfer of knowledge


    Scope of CLEF Labs

We invite submission of proposals for two types of labs:

 1.

    "Campaign-style" Evaluation Labs for specific information access
    problems (during the twelve months period preceding the conference),
    similar in nature to the traditional CLEF campaign "tracks". Topics
    covered by campaign-style labs can be inspired by any information
    access-related domain or task.

 2.

    Labs that follow a more classical "workshop" pattern, exploring
    evaluation methodology, metrics, processes, etc. in information
    access and closely related fields, such as natural language
    processing, machine translation, and human-computer interaction.

We highly recommend organisers new to the CLEF format of shared task 
evaluation campaigns to first consider organising a lab workshop to 
discuss the format of their proposed task, the problem space and 
practicalities of the shared task. The CLEF 2026 programme will reserve 
about half of the conference schedule for lab sessions.

During the conference, the lab organisers will present their overall 
results in overview presentations during the plenary scientific paper 
sessions to give non-participants insights into where the research 
frontiers are moving. Lab organisers are expected to organise separate 
sessions for their lab with ample time for general discussion and 
engagement with all participants - not just those presenting campaign 
results and papers. Organisers should plan time in their sessions for 
activities such as panels, demos, poster sessions, etc. as appropriate. 
CLEF is always interested in receiving and facilitating innovative lab 
proposals.

Potential task proposers unsure of the suitability of their task 
proposal or its format for inclusion at CLEF are encouraged to contact 
the CLEF 2026 Lab Organizing Committee Chairs to discuss its suitability 
or design at an early stage.


    Proposal Submission

Lab proposals must provide sufficient information to judge the 
relevance, timeliness, scientific quality, benefits for the research 
community, and the competence of the proposers to coordinate the lab. 
Each lab proposal should identify one or more organisers as responsible 
for ensuring the timely execution of the lab. Proposals should be 3 to 4 
pageslong and should provide the following information:

 1.

    Title of the proposed lab.

 2.

    A brief description of the lab topic and goals, its relevance to
    CLEF and the significance for the field.

 3.

    A brief and clear statement on usage scenarios and domain to which
    the activity is intended to contribute, including the evaluation
    setup and metrics.

 4.

    Details on the lab organiser(s), including identifying the task
    chair(s) responsible for ensuring the running of the task. This
    should include details of any previous involvement in organising or
    participating in evaluation tasks at CLEF or similar campaigns.

 5.

    The planned format of the lab, i.e., campaign-style (“track”) or
    workshop.

 6.

    Is the lab a continuation of an activity from previous year(s) or a
    new activity?

     1.

        For activities continued from previous year(s): Statistics from
        previous years (number of participants/runs for each task), a
        clear statement on why another edition is needed, an explicit
        listing of the changes proposed, and a discussion of lessons to
        be learned or insights to be made.

     2.

        For new activities: A statement on why a new evaluation campaign
        is needed and how the community would benefit from the activity.

 7.

    Details of the expected target audience, i.e., who do you expect to
    participate in the task(s), and how do you propose to reach them.

 8.

    Brief details of tasks to be carried out in the lab. The proposal
    should clearly motivate the need for each of the proposed tasks and
    provide evidence of its capability of attracting enough
    participation. The dataset which will be adopted by the Lab needs to
    be described and motivated in the perspective of the goals of the
    Labs; also indications on how the dataset will be shared are useful.
    It is fine for a lab to have a single task, but labs often contain
    multiple closely related tasks, needing a strong motivation for more
    than 3 tasks, to avoid useless fragmentation.

 9.

    Expected length of the lab session at the conference: half-day, one
    day, two days. This should include high-level details of planned
    structure of the session, e.g. participant presentations, invited
    speaker(s), panels, etc., to justify the requested session length.

10.

    Arrangements for the organisation of the lab campaign: who will be
    responsible for activities within the task; how will data be
    acquired or created, what tools or methods will be used, e.g., how
    will necessary queries be created or relevance assessment carried
    out; any other information which is relevant to the conduct of your lab.

11.

    If the lab proposes to set up a steering committee to oversee and
    advise its activities, include names, addresses, and homepage links
    of people you propose to be involved.

Lab proposals must be submitted via EasyChair. The link will be 
distributed, once EasyChair is set up.


    Review Process

Each proposal submitted by 14 July 2025will be reviewed by the CLEF 2026 
Lab Organising Committee. The acceptance decision will be sent by email 
to the responsible organiser by 4 Aug 2025. The final length of the lab 
session at the conference will be determined based on the overall 
organisation of the conference and the number of participant submissions 
received by a lab.


    Advertising Labs at CLEF 2025 and ECIR 2026

Organisers of accepted labs are expected to advertise their labs at both 
CLEF 2025 (September 9-12, 2025, Madrid, Spain) and ECIR 2026 (March 29 
- April 2, 2026, Delft, Netherlands). So, at least one lab 
representative should attend these events.

Advertising at CLEF 2025 will consist of displaying a poster describing 
the new lab and advertising/announcing it during the closing session.

Advertising at ECIR 2026 will consist of submitting a lab description 
(abstract submission deadline TBA by ECIR) to be included in ECIR 2026 
proceedings and advertising the lab in a booster session during ECIR 2026.


    Lab Proposals from Newcomers

If you have not organised a lab before, do not panic! The CLEF 2026 Lab 
Organising Committee Lab is willing to mentor you by offering help, 
guidance, and feedback on the writing of your draft lab proposal.

If you are a newcomer interested in receiving guidance, please send an 
e-mail with the following tag in the subject “[Mentorship CLEF 2026 Lab 
Proposals]” to Sean.MacAvaney at glasgow.ac.uk and julia.struss at
