Submission details

We accept two types of submissions:

• Extended abstracts will be published in the online pdf book of abstracts.
• Full-length papers (12-15 pages) will be published in the LNCS/LNAI Springer post-proceedings.

Both types will be treated equally when designing the conference program of oral presentations.

Further details on extended abstracts:

Extended abstracts should include 1-4 pages and may describe work-in-progress as well as research that has been published else-where during the past year. Extended abstracts will not be included in the post-proceedings. They will be published as a digital book of abstracts on the conference website. Extended abstracts must be presented at the conference to be included in the book. Extended abstracts should be prepared following the same format as full-length papers, using either the Latex or the Word templates from Springer, which can be found on the Springer authors’ page. LaTex templates are available in Overleaf.

Additional details will be updated once available.

Further details on full-length papers

Full-length papers (12-15 pages) will be published in the LNCS/LNAI Springer post-proceedings. Papers with more than 15 pages may be accepted. Papers must be original and not simultaneously submitted to another journal or conference. Each submitted paper will be reviewed by at least three independent and anonymous reviewers. All accepted papers must be presented at the conference, and will be published in the conference post-proceedings, both in print and digitally. Accepted papers will be shared for exclusive use of the conference participants during the conference.

All submissions must follow Springer’s Instructions for Proceedings Authors and use either the Latex or the Word templates, which can be found on the Springer authors’ page. LaTex templates are available in Overleaf. All submitted works should follow Springer’s Code of Conduct .

For authors who are interested in publishing open-access papers, please refer to Springer’s webpage for prices and additional information.

IJCRS2026 Special Issue of IJUFKS

https://www.worldscientific.com/worldscinet/ijufks

Description:

This special issue focuses on recent advances in uncertainty modeling, rough sets, fuzzy sets, and knowledge-based systems, with particular emphasis on high-quality contributions related to the 12th International Joint Conference on Rough Sets (IJCRS 2026).

Rough set theory and its extensions play a fundamental role in the representation and processing of imperfect, incomplete, and vague information. Over the years, strong connections have emerged between rough sets, fuzzy sets, formal concept analysis, granular computing, probabilistic reasoning, and three-way decision models. These concepts have contributed to the development of intelligent knowledge-based systems that operate under uncertainty.

The objective of this special issue is to provide a forum for extended and substantially enhanced versions of selected IJCRS 2026 papers, as well as related original contributions, presenting novel theoretical results, methodological developments, and practical applications. The special issue aims to enhance collaboration between the rough set community and the broader research domains of uncertainty, fuzziness, and knowledge-based systems, aligning with the scope of the International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, see https://www.worldscientific.com/page/ijufks/aims-scope.

Topics:

• Rough set theory, decision-theoretic rough sets, and their generalizations
• Fuzzy sets, fuzzy logic, and fuzzy inference systems
• Hybrid rough–fuzzy and fuzzy–probabilistic models
• Granular computing and information granulation
• Three-way decision models and related uncertainty frameworks
• Uncertainty representation and reasoning
• Knowledge representation and reasoning under vagueness and incompleteness
• Learning, feature selection, and data analysis using rough and fuzzy methods
• Uncertainty-aware and explainable intelligent systems
• Decision-making and optimization under uncertainty
  

Paper submissions should be made through the portal https://www.editorialmanager.com/ijufks
