Track on Knowledge Representation and Reasoning (KRR)
Website: https://krarlab.dmi.unipg.it/krrtrack/2026/

SUBMISSION DEADLINE: September 26, 2025
###############################################################

Overview
The topic of the track covers an important field of research in Artificial Intelligence: KRR is indeed a trending topic (for instance, its Argumentation-theory subfield). A similar dedicated conference is the International Conference on Principles of Knowledge Representation and Reasoning, but all the major conferences in AI (e.g., AAAI, IJCAI, AAMAS, ECAI) have KRR among their topics of interest. KRR track will be a venue for all the researchers and practitioners working on the fundaments (but also applications) of reasoning, and the cross-fertilization among different approaches (e.g., Argumentation and Belief Revision).

Scope
Knowledge-representation and Reasoning (KRR) is the field of artificial intelligence that focuses on designing computer representations that capture information about the world that can be used to solve complex problems. Its goal is to understand and build intelligent behavior from the top down, focusing on what an agent needs to know with the purpose to behave intelligently, how this knowledge can be represented symbolically, and how automated reasoning procedures can make this knowledge available as needed. In KRR a fundamental assumption is that an agent's knowledge is explicitly represented in a declarative form, suitable for processing by dedicated reasoning engines. Topics of interest include, but are not limited to:
Argumentation
Constraint solving, programming, technologies
Belief revision and update, belief merging, etc.
Commonsense reasoning
Contextual reasoning
Description logics
Diagnosis, abduction, explanation
Inconsistency- and exception tolerant reasoning, para-consistent logics
KR and autonomous agents: intelligent agents, cognitive robotics, multi-agent systems
KR and decision making, game theory, social choice
KR and machine learning, inductive logic programming, knowledge discovery and acquisition
Logic programming, answer set programming, constraint logic programming
Non-monotonic logics, default logics, conditional logics
Preferences: modeling and representation, preference-based reasoning
Reasoning about knowledge and belief, dynamic epistemic logic, epistemic and doxastic logics
Reasoning systems and solvers, knowledge compilation
Spatial reasoning and temporal reasoning, qualitative reasoning
Uncertainty, representations of vagueness, many-valued and fuzzy logics

Submissions
We would like to invite authors to submit papers on research on KRR area, with particular emphasis on assessing the current state of the art and identifying future directions. Original papers addressing any of the listed topics of interest (or related topics) will be considered. Each submitted paper will be fully refereed and undergo a double-blind review process by at least three referees. Accepted papers will be included in the ACM SAC 2024 proceedings and published in the ACM digital library, being indexed by Thomson ISI Web of Knowledge and Scopus. Submissions fall into the following categories:
Original and unpublished research work
Reports of innovative computing applications in the arts, sciences, engineering, and business areas
Reports of successful technology transfer to new problem domains
Reports of industrial experience and demos of new innovative systems

Regular Paper Submissions
Submissions should be properly anonymised to facilitate blind reviewing. The author(s) name(s) and address(es) must not appear in the body of the paper, and all self-references should be written in the third person.
Please check the Author Kit and LaTeX style files available on the main SAC website. The required format is typically based on the ACM templates. Submissions that do not comply with the formatting or length requirements may be subject to immediate rejection.

All submissions must be made electronically via the EasyChair platform:
https://easychair.org/my/conference?conf=sac2026

Papers receiving high-quality reviews but not accepted due to space limitations may be invited to participate in the poster session.

SRC Abstract Submissions
Graduate students are invited to submit abstracts that present original, unpublished, and in-progress research related to this track. SRC overview at this link https://www.sigapp.org/sac/sac2026/src_program.php.

Submit your abstract via:
https://easychair.org/my/conference?conf=sacsrc2026

Accepted papers instructions:
Accepted, papers must fit within eigth (8) two column pages, with the option for up to 2 additional pages at additional cost.
A second set of selected papers, which did not get accepted as full papers, will be accepted as posters, limited to 2 pages with the option for up to 1 additional page at additional cost.
Authors of accepted papers must be prepared to sign a copyright statement and must pay the registration fee and guarantee that their paper will be presented at the conference. No-show of scheduled papers will result in excluding the papers from the ACM/IEEE digital library.
