Exploring the concepts of modularity and independence, this book delves into both classical and nonclassical logics, emphasizing many-valued logics and various structures. It examines neighbourhood semantics and their relationship to independence, highlighting similarities and differences among different logical systems. The comprehensive analysis offers insights into the intricate connections within the field of logic, making it a valuable resource for those interested in advanced logical theories.

"Goal Directed Proof Theory" offers a comprehensive methodology for automated deduction in non-classical logics, crucial for computer science. It generalizes logic programming for efficient proof search across various logical systems, serving as an introductory resource for those interested in automated reasoning. Suitable for self-study with basic logic knowledge.

These tools include preferential reasoning, theory revision, and reasoning in inheritance systems, and the authors use these tools to examine nonmonotonic logic, deontic logic, counterfactuals, modal logic, intuitionistic logic, and temporal logic.

Exploring Dung's abstract argumentation frames, the book presents them as a versatile network structure akin to various systems like neural networks and ecological models. It employs meta-logical methods to enhance understanding of argumentation while also integrating concepts from argumentation theory into broader logical frameworks and network theory. Key discussions include the interplay between argumentation and general logics, as well as the implications for network analysis.

This book explores logical systems related to Heyting's implication, emphasizing properties of classical connectives. It includes insights for intuitionist mathematicians and discusses topological models and type theories. The author acknowledges contributions from Professors Kreisel, Rabin, and Scott, highlighting their influence on the work.

In this book the authors present new results on interpolation for nonmonotonic logics, abstract (function) independence, the Talmudic Kal Vachomer rule, and an equational solution of contrary-to-duty obligations. The chapter on formal construction is the conceptual core of the book, where the authors combine the ideas of several types of nonmonotonic logics and their analysis of 'natural' concepts into a formal logic, a special preferential construction that combines formal clarity with the intuitive advantages of Reiter defaults, defeasible inheritance, theory revision, and epistemic considerations. It is suitable for researchers in the area of computer science and mathematical logic.

This text offers an extension to the traditional Kripke semantics for non-classical logics by adding the notion of reactivity. Reactive Kripke models change their accessibility relation as we progress in the evaluation process of formulas in the model. This feature makes the reactive Kripke semantics strictly stronger and more applicable than the traditional one. Here we investigate the properties and axiomatisations of this new and most effective semantics, and we offer a wide landscape of applications of the idea of reactivity. Applied topics include reactive automata, reactive grammars, reactive products, reactive deontic logic and reactive preferential structures. Reactive Kripke semantics is the next step in the evolution of possible world semantics for non-classical logics, and this book, written by one of the leading authorities in the field, is essential reading for graduate students and researchers in applied logic, and it offers many research opportunities forPhD students.

Agents act on the basis of their beliefs and these beliefs change as they interact with other agents. In this book the authors propose and explain general logical tools for handling change. These tools include preferential reasoning, theory revision, and reasoning in inheritance systems, and the authors use these tools to examine nonmonotonic logic, deontic logic, counterfactuals, modal logic, intuitionistic logic, and temporal logic. This book will be of benefit to researchers engaged with artificial intelligence, and in particular agents, multiagent systems and nonmonotonic logic.

This book constitutes the refereed proceedings of the First International Joint Conference on Qualitative and Quantitative Practical Reasoning, ECSQARU-FAPR'97, held in Bad Honnef, Germany, in June 1997. The volume presents 33 revised full papers carefully selected for inclusion in the book by the program committee as well as 12 invited contributions. Among the various aspects of human practical reasoning addressed in the papers are nonmonotonic logics, default reasoning, modal logics, belief function theory, Bayesian networks, fuzzy logic, possibility theory, inference algorithms, dynamic reasoning with partial models, and user modeling approaches.

This book constitutes the refereed proceedings of the International Conference on Formal and Applied Practical Reasoning, FAPR '96, held in Bonn, Germany, in June 1996. The 51 revised full papers included in the book together with eight posters were carefully selected for presentation at the conference. The book addresses current aspects of the highly interdisciplinary area of practical reasoning in artificial intelligence, philosophy, psychology, linguistics, software engineering, intelligent systems, and industrial applications. Among the topics addressed are user modeling, belief, legal reasoning, argumentation, dialogue logic, default reasoning, analogy, metareasoning, temporal and procedural reasoning, and many others.
