Taschenbuch. Etat : Neu. Neuware -This book constitutes the refereed proceedings of the 17th International Conference on Conceptual Structures, ICCS 2009, which took place in Moscow, Russia, on July 26-31, 2009.The 18 papers presented together with 5 invited contributions were carefully reviewed and selected from approximately 50 submissions. Originally centered around research on knowledge representation and reasoning with conceptual graphs, over the years ICCS has broadened its scope to include innovations from a wider range of theories and related practices, among them other forms of graph-based formalisms like RDF or existential graphs, formal concept analysis, semantic Web technologies, ontologies, concept mapping and more. 321 pp. Englisch.…

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - The aim of contextual logic is to provide a formal theory of elementary logic, which is based on the doctrines of concepts,judgements, and conclusions. Concepts are mathematized using FormalConcept Analysis (FCA), while an approach to the formalization of judgements andconclusions is conceptual graphs, based on Peirce's existential graphs.Combining FCAand a mathematization of conceptual graphs yields so-called concept graphs, which offer a formal and diagrammatic theory of elementary logic. Expressing negation in contextual logic is a difficult task. Based on the author's dissertation, this book shows how negation on the level ofjudgements can be implemented. To do so, cuts (syntactical devices used to expressnegation) are added to concept graphs. As we can express relations between objects, conjunction and negation in judgements, and existential quantification, the author demonstrates that concept graphs with cuts have the expressive power of first-order predicate logic. While doing so, the authordistinguishes between syntax and semantics, and provides a sound and completecalculus for concept graphs with cuts.The author's treatment ismathematically thorough and consistent, and the book gives the necessarybackground on existential and conceptual graphs.…
