We invite submissions of demo papers for ECML PKDD 2025. Demos present a valuable and unique opportunity to showcase innovative research and get direct feedback from the research community. Submissions should describe working systems based on state-of-the-art machine learning and data mining technology. Systems should demonstrate that they go beyond basic statistics and leverage machine learning techniques and knowledge discovery processes in a real setting. Commercial software systems are not acceptable. The accepted demo papers will be included in the conference proceedings and published by Springer Verlag in the "Lecture Notes in Computer Science" (LNCS) series. The submissions also have to include a short promotional video. The demos will be presented in a dedicated session. At least one of the demo authors must register for the conference and perform the demo on-site. The proceedings will be published after the conference and include only the papers the authors have presented. During the conference, camera-ready versions of the papers will be available for conference participants. Unlike the Research and ADS Tracks, we will apply a single-blind review process for the demo submissions (authors' identities known to reviewers). The paper must provide adequate information on the system's components and the way the system is operated, including, e.g., screenshots and a use case. Authors should remember that the description of a demo has inherently different content than a research paper submitted to the main conference. A successful demonstration paper should tackle the following questions:

• What are the innovative aspects, and in what way/area does it represent the state of the art?
• Who are the target users, and why is the system interesting/useful to them?
• If there are similar/related pieces of software, what are the advantages and disadvantages of the one presented?

The submission site will be announced soon.

A demonstration submission can be up to four pages long, including references. The paper should contain a URL linking to a demonstration video of at most 5 minutes. This video should show and explain the execution of the system as it will be done at the conference. It may be a mixture or combination of a demo, voice-over (Powerpoint, PDF slides, etc.), and screencast presentations showing and explaining what happens. It should include subtitles in English. Papers must be written in English and formatted according to the Springer LNCS guidelines. Author instructions, style files, and copyright forms can be downloaded. Springer LNCS Template Download Example demo papers from past editions can be found.
