Neural approaches have traditionally excelled at perceptual tasks like pattern recognition, whereas symbolic frameworks have offered powerful methods for knowledge representation, logical inference, and interpretability, but the current AI landscape is increasingly defined by hybrid systems that blend these complementary paradigms. This is particularly relevant in the context of knowledge graphs (KGs), which serve as a bridge between symbolic logic and the subsymbolic world of deep learning.

The Handbook on Neurosymbolic AI and Knowledge Graphs deals with state-of-the-art neurosymbolic and KG-based AI, reflecting an ecosystem in which large language models, deep neural networks, and symbolic representations converge. It illustrates the progress that has been made, while also revealing emerging challenges in trustworthiness, interpretability, and scalability. The first four chapters are on the foundations of neural and symbolic AI. In the following chapters the authors explore the nuances of KG representation and embeddings, moving on to KG construction, integration, and quality, and covering challenges such as entity alignment, canonicalization, fusion, and the critical aspect of uncertainty management. Offering solutions that seamlessly combine symbolic logic with deep learning pipelines, the handbook deals with question answering, program synthesis, and dynamic KG methods, before moving on to the need to ensure transparency, accountability, and trust in systems operating on increasingly complex data. The final chapters demonstrate problem solving across news analytics, literary studies, life sciences, food computing, social media, and more.

This work offers a comprehensive overview of these intersecting fields and will be of interest to researchers and developers looking for a practical guide to building AI systems that are robust, transparent, and ethically grounded.

Preparing Robots for Life in the Real World

It is anticipated that real-world autonomous systems, such as AI-enabled robotic systems and intelligent transportation systems, will increasingly be deployed in real-world environments within the next few decades, precluding mundane human work, providing new services, and facilitating smarter and more flexible infrastructure in workplaces, public spaces, and homes. For such systems to be safe and secure, especially around people, it is important that they are explainable, predictable, and can deal with a real world that is constantly changing and only partially observable.

This book, Safety-Aware Autonomous Systems - Preparing Robots for Life in the Real World, investigates ways for autonomous systems to deal with dynamic and changing environments consistently and safely. The need for sound uncertainty management and the explicit uncertainty quantification required to provide probabilistic safety guarantees is explored, as is the runtime monitoring necessary to ensure safety in new situations. The realization of well-grounded prediction and classification uncertainty and the capacity to deal with unknown unknowns using anomaly detection are also interrogated. The degree of safety required can make it very challenging to reach useful levels of efficiency and effectiveness in safety-critical applications. To this end, a holistic perspective on agent motion in complex and dynamic environments is investigated. The book also discusses the leveraging of the synergies in well-founded formalized interactions, and the integration between learning, reasoning, and interaction.

Demonstrating efficient, effective, and safe capabilities for autonomous systems in safety-critical situations, the book will be of interest to all those working in the field.

Integrating Logical and Cognitive Theories of Concepts

What is a concept? Philosophy, cognitive science, psychology, logic, and AI have long been inquiring into this question. However, answers rarely converge.

The question of how humans represent and combine concepts has become increasingly relevant to AI. Despite advancements in Large Language Models and statistical models generally, the goal of developing formal representations of human thinking remains as crucial as ever. Cognitive models of human conceptualisation are of pivotal importance for AI and Knowledge Representation. Nevertheless, such models often lack proper formalisation, which makes it difficult to capture them precisely in computational systems. At the same time, the cognitive adequacy of computational systems is frequently overlooked in favour of better performance.

This book, Combining Concepts - Integrating Logical and Cognitive Theories of Concepts, bridges the gap between computational and cognitive models of concepts. The author explores the relationship between conceptual combination, the associated cognitive phenomena, and standard logical operators. The book introduces a representation of concepts motivated by the literature in cognitive psychology, combining ontological analysis, logical methods, and insights from statistical learning to offer a more cognitively grounded approach to modelling concepts and concept combination in Knowledge Representation and AI. It thus contributes to the development of hybrid AI modelling techniques, bridging learning and reasoning, and ensuring that they are theoretically sound, cognitively adequate, psychologically motivated, and practically applicable.

Offering a thorough exploration of concepts and concept combinations as they relate to current applications, the book will be of interest to all those working in the fields of AI and Knowledge Representation.

An Artificial Intelligence (AI) agent can perceive an environment through sensors and act in the environment through actuators. When performing tasks in a known environment, an agent knows what actions it can execute and how they affect the environment state, but when the environment is unknown, the agent needs to learn how the environment works to make good decisions for accomplishing tasks. In a real-world situation, an agent may have only low-level perceptions of the environment rather than the high-level representations required to make decisions by means of symbolic planning.

This book, Integrating Planning and Learning for Agents Acting in Unknown Environments proposes an architecture that integrates learning, planning, and acting. The author, Leonardo Lamanna, won the 2023 Marco Cadoli award, an annual award from the Italian Association for Artificial Intelligence (AIxIA) for the best doctoral thesis in the field of artificial intelligence, for this work. The approach combines data-driven learning methods for building an environment model with symbolic planning techniques for reasoning on the learned model, focusing on learning the model, either from continuous or symbolic observations. The problem of online learning the mapping between continuous perceptions and symbolic states is tackled, and symbolic planning techniques are exploited to enable an agent to autonomously gather relevant information online, which is required by learning methods to overcome some of the simplifying assumptions of symbolic planning. The effectiveness of the approach in simulated complex environments is shown experimentally and the applicability of the approach in real environments is demonstrated by conducting experiments on a real robot.

Outperforming state-of-the-art methods, the approach described in this book will be of interest to all those working in the field of AI and autonomous agents.

Proceedings of Robophilosophy 2024

The novel capacities of multimodal generative AI have suddenly brought us much closer to the longstanding vision of ubiquitous social robotics. Robots may soon become part of everyday life, performing many services as well or better than humans. We have entered a decisive phase in the robotic moment of human cultural history, and it is more urgent than ever that we determine “who we are and who we are willing to become” (Sherry Turkle).

This book presents the proceedings of RP2024, the sixth event in the biennial Robophilosophy Conference Series, held from 20 to 23 August 2024 in Aarhus, Denmark. Robophilosophy conferences are the world’s largest events for fully interdisciplinary social-robotics research, featuring contributions from humanities and social-science research in HRI, robotics, AI research, and cognitive science, as well as art events.

RP2024 explored the questions of socio-cultural transformation that can be expected to ensue from the new technological potential of social robotics. As is characteristic for the conferences in this series, RP2024 addressed not only questions of concrete practice, but also the deeper theoretical and existential issues that reach far beyond safety and privacy concerns into the conceptual and normative fabric of our societies and our individual self-comprehension.

The book is divided into 3 parts. Part 1 contains abstracts of the 8 plenary sessions; Part 2 contains 55 session papers divided into 8 sections; and Part 3 contains details of the 10 workshops which formed part of the conference.

The book showcases the way in which technical empirical, conceptual and phenomenological research can make a concrete contribution to the necessary collaborative effort, and will be of interest to all those working in the field.
