Knowledge Representation and Reasoning (KR) is a well-established and lively field of research. In KR a fundamental assumption is that an agent's knowledge is explicitly represented in a declarative form, suitable for processing by dedicated reasoning engines. This assumption, that much of what an agent deals with is knowledge-based, is common in many modern intelligent systems. Consequently, KR has contributed to the theory and practice of various areas in AI, including automated planning and natural language understanding, and to fields beyond AI, including databases, verification, software engineering, and robotics. In recent years, KR has contributed also to new and emerging fields, including the semantic web, computational biology, cyber security, and the development of software agents.

The KR conference series is the leading forum for timely in-depth presentation of progress in the theory and principles underlying the representation and computational management of knowledge. The KR2022 program will also feature workshops and tutorials, solicited by means of an open call, as well as a doctoral consortium. In addition to the main conference track, KR2022 will host the following tracks and sessions: - Applications and Systems Track - Recently Published Research Track - Special Session on KR and Machine Learning - Special Session on KR and Robotics. KR 2022 will be held as part of the Federated Logic Conference (FLoC 2022) in Haifa, Israel, from July 31 to August 12, 2022. The KR-affiliated FLoC tutorials and workshops will take place directly before KR, on July 31-August 1. All events that are part of FLoC are currently planned to take place physically, but people can participate remotely in cases where travel is impossible.

The 22nd Trends in Logic workshop, entitled "Strong & Weak Kleene Logics", will take place at the University of Cagliari (Cagliari, Italy) from 18–20 July 2022. It is organized by the ALOPHIS research group of the Department of Pedagogy, Psychology and Philosophy.

The aim of the workshop is to bring together researchers working on various facets of logics related to the strong and weak Kleene systems, be they algebraic, proof-theoretic, or philosophical. The workshop will be held in a hybrid format, with in-person as well as online sessions. The workshop will be followed by another event on neighbouring topics, the second installment of Workshop on Relating Logics from July 22--23.

Computational and technological developments that incorporate natural language are proliferating. Adequate coverage encounters difficult problems related to partiality, underspecification, and context-dependency, which are signature features of information in nature and natural languages. Furthermore, agents (humans or computational systems) are information conveyors, interpreters, or participate as components of informational content. Generally, language processing depends on agents' knowledge, reasoning, perspectives, and interactions.

The session covers theoretical work, applications, approaches, and techniques for computational models of information and its presentation by language (artificial, human, or natural in other ways). The goal is to promote computational systems of intelligent natural language processing and related models of thought, mental states, reasoning, and other cognitive processes.

FSCD covers all aspects of formal structures for computation and deduction from theoretical foundations to applications. Building on two communities, RTA (Rewriting Techniques and Applications) and TLCA (Typed Lambda Calculi and Applications), FSCD embraces their core topics and broadens their scope to closely related areas in logics, models of computation, semantics and verification in new challenging areas.

IJCAR is the premier international joint conference on all topics in automated reasoning. It is the merger of leading events in automated reasoning: CADE (Conference on Automated Deduction), FroCoS (Symposium on Frontiers of Combining Systems), ITP (International Conference on Interactive Theorem Proving) and TABLEAUX (Conference on Analytic Tableaux and Related Methods). IJCAR 2022 will be part of the Eighth Federated Logic Conference (FLoC 2022).

The link between epistemic logic and topology has its roots, on the one hand, in the topological semantics of modal logic, and on the other hand, in the intimate relations between topology and concurrency, and between topology and distributed computing. Recent years have witnessed an explosion of new work in this area, from the development of more expressive logics capable of capturing fine topological structure, to the leveraging of topological tools to represent concepts such as observations, questions, and dependence relations, and encoding deep connections with distributed computing. The richness of this area has spawned a thriving, interdisciplinary research program with applications in learning theory, network epistemology, public and private communication, inquisitive semantics, philosophy of science, and knowledge representation in distributed computing, among others.

This workshop aims at bringing together scholars working on various ways of connecting logic and topology to showcase a variety of recent developments and applications in the area, and to foster new research collaborations.

Explainable AI (XAI) has been identified as a key factor for developing trustworthy AI systems. The reasons for equipping intelligent systems with explanation capabilities are not limited to user rights and acceptance. Explainability is also needed for designers and developers to enhance system robustness and enable diagnostics to prevent bias, unfairness, and discrimination, as well as to increase trust by all users in why and how decisions are made. XAI focuses on developing new approaches for explanations of black-box models by achieving good explainability without sacrificing system performance. This special issue will feature contributions dedicated to the role played by knowledge bases, ontologies, and knowledge graphs in XAI, in particular with regard to building trustworthy and explainable decision support systems.

LCC meetings are aimed at the foundational interconnections between logic and computational complexity, as present, for example, in implicit computational complexity (descriptive and type-theoretic methods); deductive formalisms as they relate to complexity (e.g. ramification, weak comprehension, bounded arithmetic, linear logic and resource logics); complexity aspects of finite model theory and databases; complexity-mindful program derivation and verification; computational complexity at higher type; and proof complexity. The program will consist of invited lectures as well as contributed talks selected by the Program Committee.

We invite authors to submit papers for a Special Issue on "Formal and Cognitive Reasonig" to be published in the Journal of Applied Logics (IfCoLog Journal of Logics and Their Applications, College Publications). In September 2021, the 7th Workshop on Formal and Cognitive Reasoning (FCR-2021) took place. In the special issue, original contributions on the basis of the best contributions presented at the workshop will be published, and we also welcome contributions from other authors.

Aims and Scope: Information for real life AI applications is usually pervaded by uncertainty and subject to change, and thus demands for non-classical reasoning approaches. At the same time, psychological findings indicate that human reasoning cannot be completely described by classical logical systems. Sources of explanations are incomplete knowledge, incorrect beliefs, or inconsistencies. A wide range of reasoning mechanism has to be considered, such as analogical or defeasible reasoning, possibly in combination with machine learning methods. The field of knowledge representation and reasoning offers a rich palette of methods for uncertain reasoning both to describe human reasoning and to model AI approaches.

The philosophical tradition of logic overlapped with the development of modern mathematical logic from the first versions of the algebra of logic in the mid nineteenth-century until inquiries into the logical foundations of mathematics from the early 1930s. This very fact strongly suggests that there might have been significant intersections between what appear now as separate disciplines, and raises the question of whether philosophical roots can be traced in the development of mathematical logic.The aim of this conference is to foster further exchanges between those who are doing scholarly research on the history of logic in the nineteenth and early twentieth centuries from various perspectives, including those who focus on the philosophical tradition of the nineteenth century and its developments in neo-Kantianism and phenomenology, historians of logic and of related mathematical disciplines, as well as philosophers who are interested in the epistemological issues surrounding modern mathematical logic.

The conference will take place at the University of Turin, Italy. It is planned as a hybrid event with face-to-face sessions and one online session.
