<p><strong><span style="font-size: 12pt;">Call for Papers - Applications & Systems Track</span></strong></p>
<p>Systems and applications incorporating Knowledge Representation and Reasoning (KR) have made tremendous progress over the last decades and become more and more pervasive in scientific, industrial and everyday life. Popular knowledge representation formalisms range from databases, ontologies, classical, probabilistic and non-monotonic logics to natural language, offering rich means to describe a variety of static as well as dynamic phenomena. Automated reasoning systems harness machine learning, combinatorial search and optimization methods, planning, proving, design and diagnosis techniques to provide powerful tools for analyzing and deriving conclusions from complex input data. Novel, general and interdisciplinary approaches are thus vital contributions at the intersection of science, industry and society, aiming to enhance the capabilities and outreach of KR principles and technologies.</p>
<p>This year, for the fourth time, KR 2023 will host a track on "Applications and Systems". The Applications and Systems Track aims at providing researchers and industrial practitioners with a dedicated forum for presentation and discussion of new ideas, research experience and emerging results on topics related to applications of KR formalisms and automated reasoning systems. This track provides the opportunity for fostering meaningful connections between researchers from both practical and theoretical areas of AI and, at the same time, offers participants the possibility to learn about progress made on these topics, share their own views and elaborate about approaches that could lead to effective cross-fertilisation among research in challenging KR applications and new innovative systems for solving them.</p>
<p>Expected Contributions</p>
<p>The Applications and Systems Track at KR 2023 invites submissions of papers on all aspects of the development, deployment, and evaluation of KR systems to solve significant and challenging application problems, including:</p>
<p>● case studies, including suitable descriptions of the problem setting, data and tools used, and "lessons learnt",<br />● use cases, including task specifications, related tasks/approaches, challenges, and a sketch of possible KR solution,<br />● benchmarks, including suitable descriptions of the dataset, reasoning tasks, and ideally some "solution set" or gold standard,<br />● system descriptions, including descriptions of the algorithm, implementation<br />● and empirical evaluation on a suitable dataset.</p>
<p>We welcome the above kinds of papers on a wide range of topics, including papers describing KR systems, tools, solvers and reasoning engines, as well as papers reporting on applications of KR systems in solving or supporting tasks related to different application areas and settings.</p>
<p>Application areas of interest include but are not restricted to: computational biology, computer vision and image recognition, creative computing, cybersecurity and blockchain, data analysis, databases and query answering, decision support, declarative problem solving, diagnosis and explanation, game theory and social choice, human-computer interaction, intelligent transportation and logistics, intelligent user interfaces, internet of things, machine learning, natural language processing, digital forensics, robotics and human-robot collaboration, semantic web and knowledge graphs, software engineering, and system design. We also welcome submissions talking about interdisciplinary applications of KR, for example in economics, education, life sciences, medicine, and pharmacology, among others.</p>
<p>Submission Guidelines and Evaluation Criteria</p>
<p>The Applications and Systems Track will allow contributions of both regular papers (9 pages) and short papers (4 pages), excluding references, prepared and submitted according to the authors guidelines in the submission page.</p>
<p>The track emphasizes applications of KR and development of KR systems, and welcomes contributions showcasing the impact of KR research as well as driving future research by presenting challenging data, use cases and problems together with observations and insights gained.</p>

<p><strong><span style="font-size: 12pt;">Call for Papers - Special Session on KR & ML</span></strong></p>
<p>The last few years have witnessed a growing interest in AI methods that combine aspects of Machine Learning (ML) with insights and methods from the field of Knowledge Representation and Reasoning (KR). This trend is motivated by the clear complementarity of ML and KR. For instance, the popularity and success of ML based systems has put issues such as explainability, bias, fairness, sustainability, symbol grounding and so forth, firmly in the spotlight, and addressing these issues naturally leads to systems in which symbolic representations play a central role. On the other hand, ML also offers solutions for long-standing challenges in the field of KR, for instance related to efficient, neurally-guided, noise-tolerant and ampliative inference, knowledge acquisition, and the<br />limitations of symbolic representations. The synergy between ML and KR has the potential to lead to new advancements in fundamental AI challenges including, but not limited to, learning symbolic generalisations from raw (multi-modal) data, using knowledge to facilitate data-efficient learning, speeding up inference, supporting interpretability of learned outcomes and integration of symbolic planning and reinforcement learning.</p>
<p>This year, for the third time, KR2023 will host a special session on "Knowledge Representation and Machine Learning", which aims at providing researchers and practitioners with a dedicated forum for the discussion of new ideas and research results at the intersection of these two fields. This special session will provide participants with the opportunity to make meaningful connections and develop a shared understanding of the challenges involved in developing innovative AI solutions that rely on a combination of insights and methods from ML and KR.</p>
<p>Expected Contributions</p>
<p>The Special Session on KR and ML at KR2023 invites submissions of papers that combine aspects of KR and ML research, including the use of KR methods for solving ML challenges (e.g. knowledge-guided or explainable learning), the use of ML methods for solving KR challenges (e.g. efficient inference, knowledge base completion), the integration of learning and reasoning at modeling or solving side, and the application of combined KR and ML approaches to solve real-world problems.</p>
<p>We welcome papers on a wide range of topics, including but not limited to:</p>
<p>• Learning symbolic knowledge, such as ontologies and knowledge graphs, action theories, commonsense knowledge, spatial and temporal theories, preference models and causal models<br />• Logic-based, logical and relational learning algorithms<br />• Machine-learning driven reasoning algorithms<br />• Neural-symbolic learning<br />• Statistical relational learning<br />• Symbolic reinforcement learning<br />• Learning symbolic abstractions from unstructured data<br />• Explainable AI<br />• Expressive power of learning representations<br />• Knowledge-driven natural language understanding and dialogue<br />• Knowledge-driven decision making<br />• Knowledge-driven intelligent systems for internet of things and cybersecurity<br />• Architectures that combine data-driven techniques and formal reasoning</p>
<p>Submission Guidelines and Evaluation Criteria</p>
<p>The Special Session on KR and ML will allow contributions of both regular papers (9 pages) and short papers (4 pages), excluding<br />references, prepared and submitted according to the authors guidelines in the submission page.</p>
<p>The special session welcomes contributions that extend the state-of-the-art at the intersection of KR and ML. Therefore, KR-only or<br />ML-only submissions will not be accepted for evaluation in this special session.</p>
<p>Submissions will be rigorously peer reviewed by PC members who are active in KR and ML. Submissions will be evaluated on the basis of the originality, soundness, relevance and significance of the technical contribution, as well as the overall presentation quality.</p>

<p><strong><span style="font-size: 12pt;">Call for Applications - Doctoral Consortium</span></strong></p>
<p>The 20th International Conference on Principles of Knowledge Representation and Reasoning (KR 2023) invites PhD students to apply for the Doctoral Consortium program.</p>
<p>Aims and Scope</p>
<p>The Doctoral Consortium (DC) is a student mentoring program bringing together PhD students and senior researchers from the area of KR. The aims of the consortium are:</p>
<p>● to provide a forum for students to present their current research, and receive feedback from other students and senior researchers;<br />● to promote contacts among PhD students working in similar areas;<br />● to support students with information and advice on academic, research, and industrial careers.</p>
<p>The DC is intended for PhD students who have a specific research proposal and some preliminary results, but who have sufficient time prior to completing their dissertation to benefit from the consortium experience. Preference will be given to students satisfying these criteria, but we also encourage students to apply who are at an earlier or more advanced stage of the completion of their thesis. Accepted students will participate in several dedicated DC events, which will likely consist of a lightning talk session and a poster and mentoring session (the precise format of the DC will be finalized closer to the conference). Each student will be given ample time to present their work and therefore be able to fully benefit from direct feedback from the assigned senior researcher mentor and the wider KR conference audience.</p>
<p>Application Submission</p>
<p>Applications must be submitted through the EasyChair conference system:</p>
<p>https://easychair.org/conferences/?conf=kr2023</p>
<p>Each application must contain the following elements combined into a single PDF document:</p>
<p>1. Thesis summary. A description of the problem being addressed, your motivation for addressing the problem, proposed plan of research, the progress to date (what you have already achieved and what remains to be done), and related work. The maximum number of pages is four (bibliography included) and the same style as for KR paper submissions should be used (see https://kr.org/KR2023/).<br />2. Curriculum Vitae. A description of your background and relevant experience (research, education, employment), maximum two pages.<br />3. Brief letter of recommendation. A brief letter from your thesis advisor that states that she/he supports your participation in the DC.<br />4. Optionally, a suggestion of some potential mentors with similar research interests, who could give good advice on technical aspects related to the work, and/or career opportunities.</p>
<p>The selection process will consider the quality of the submitted proposal and the stage of the student's PhD project. Doctoral students who submit to the DC are permitted to have previously published their research, and are encouraged to submit papers to KR 2023 and associated conferences and workshops.</p>
