Call for Contributions

VARIABILITY 2026 invites Journal-First presentations of papers recently published in leading software engineering journals, including TSE, TOSEM, IST, EMSE, JSS, ASEJ, SoSyM, and reputable open-access journals. This initiative provides authors with the opportunity to engage directly with the VARIABILITY community, while offering attendees a richer and more diverse program. The Journal-First papers remain published in their respective journals, and a one-page summary will be included in the VARIABILITY 2026 proceedings with a pointer to the original publication.

Scope

To qualify for a Journal-First presentation at VARIABILITY 2026, a paper must meet these criteria:

  • It was published on the publisher’s website between November 2024 and March 2026.
  • It fits within the scope of VARIABILITY 2026, as described in the research track call, and can bring new insights or directions to the community.
  • It presents new research results or significant extensions of prior work that have not been presented at SPLC, VaMoS, or ICSR before.
  • It has not been presented at, and is not under review for, Journal-First Tracks of other related conferences.

How to Submit

Authors of papers that meet the above criteria are invited to submit a short proposal for presentation. The proposal should be one page and include the following:

Accepted abstracts will be published in the VARIABILITY 2026 Proceedings. By submitting your abstract for inclusion in these proceedings, you acknowledge that you and your co-authors must comply with Springer’s publication policies, including requirements related to research integrity, copyright, and ethical standards. Any alleged violations of these policies may be investigated by Springer and could result in corrective actions, including withdrawal of the paper.

Evaluation and Selection

Proposals will be selected based on the quality of the publication and the journal, after confirming that the paper fits the scope of the conference. Since the papers have already been peer-reviewed and accepted by their journals, they will not undergo another technical review. The goal is to include as many papers as possible in the Journal-First Track. However, if an unusually high number of papers are received, some might not be accepted. If needed, priority will be given to papers that best align with the conference topics of interests and the structure of the sessions.

Important Dates (AoE)

  • Journal-First Submissions Deadline: Thu 2 Apr Mon 01 June 2026
  • Journal-First Acceptance Notification: Mon 22 Jun 2026
  • Journal-First Camera-ready Deadline: Wed 15 Jul 2026
  • Submissions close at 23:59 AoE (Anywhere on Earth, UTC-12)

Conference Attendance

For each paper accepted into the Journal-First Track, at least one author must register for the conference and attend to give the oral presentation.
