    Designing Cognitive Cities

    No full text
    The following text intends to give an introduction into some of the basic ideas which determined the conception of this book. Thus, the first part of this article introduces the terms “City”, “Smart City” and “Cognitive City”. The second part gives an overview of design theories and approaches such as Action Design Research and Ontological Design (a concept in-the-making), in order to deduce from a theoretical point of view some of the principles that needs to be taken into account when designing the Cognitive City. The third part highlights some concrete techniques that can be usefully applied to the problem of citizen communication for Cognitive Cities (namely Metaheuristics, Fuzzy Sets and Fuzzy Logic, Computing with Words, Computational Intelligence Classifiers, and Fuzzy-based Ontologies). Finally, we introduce the articles of this book

    A Dynamic Route Planning Prototype for Cognitive Cities

    No full text
    A software prototype for dynamic route planning in the travel industry for cognitive cities is presented in this paper. In contrast to existing tools, the prototype enhances the travel experience (i.e., sightseeing) by allowing additional flexibility to the user. The theoretical background of the paper strengthens the understanding of the introduced concepts (e.g., cognitive cities, fuzzy logic, graph databases) to comprehend the presented prototype. The prototype applies an instantiation and enhancement of the graph database Neo4j . For didactical reasons and to strengthen the understanding of this prototype a scenario, applied to route planning in the city of Bern (Switzerland) is shown in the paper

    Fuzzy Logic, Concepts and Semantic Transformers

    No full text
    In standard fuzzy logic, the meaning of a predicate is identified with a fuzzy extension, i.e. a fuzzy set. This approach abstracts away from the semantic function of concepts. Informally speaking, a concept is a structure in our semantic memory that allows us to categorize objects into the extension of a predicate. In this paper, I present an implementation of concepts in fuzzy logic. The implementation allows fuzzy logic to extend its functional scope. I discuss one new function, i.e. the modeling of fuzzy reasoning with semantic transformers. Semantic transformers are words and phrases that are capable of transforming the meaning of predicates. Intuitive examples are technically and loosely speaking, e.g. “Technically speaking, Richard Nixon is a Quaker” and “Loosely speaking, a vase can be called furniture.

    Fuzzy thinking in sociology

    "The well-known distinction between soft and hard science cuts a sharp line of demarcation between hard and soft facts of scientific studies. Physics deal with precise hard facts characteristically whereas social sciences are confronted with imprecise soft social facts because social facts are notoriously vague, interpretative facts of meaning. Therefore Fuzzy logic seems to fit perfectly the needs of social scientist that look for mathematical precise models to deal with vague, imprecise data [52]. In this contribution we discuss the usefulness of Fuzzy logic for social sciences in general, and especially sociology. In a first step we summarize some fundamentals of 'fuzzy thinking' for social scientist. This will lead to the discussion of the need of fuzzy thinking in action theory, systems theory, modernization theory and empirical research.We discuss the advantage of fuzzy thinking for action theory and social systems theory at length whereas the discussion of fuzzy thinking in modernization theory and empirical research falls short. Modernization theory and empirical research just function as further examples for the need and usefulness of fuzzy thinking." (excerpt

    From Trillas’ Negations and Antonyms to a Set Representation of Contradiction Within Bipolar and Other Extensions of Fuzzy Sets

    A Festschrift book to Enric Trillas RuizIn 1979, Enric Trillas started to interest in in fuzzy connectives. His first paper on this topic was ”Funciones de negacin en la teora de subconjuntos difusos” ([9]) (Negation functions in the theory of fuzzy subsets), which appeared in Spanish in the Stochastica journal. This work, focused on the characterization of strong negations, has been so relevant for the development of fuzzy theory that it was translated into English and widely cited in the last 35 yearsDepto. de Estadística e Investigación OperativaFac. de Ciencias MatemáticasTRUEpu
