    Presently, a very large number of public and private data sets are available from local governments. In most cases, they are not semantically interoperable and a huge human effort would be needed to create integrated ontologies and knowledge base for smart city. Smart City ontology is not yet standardized, and a lot of research work is needed to identify models that can easily support the data reconciliation, the management of the complexity, to allow the data reasoning. In this paper, a system for data ingestion and reconciliation of smart cities related aspects as road graph, services available on the roads, traffic sensors etc., is proposed. The system allows managing a big data volume of data coming from a variety of sources considering both static and dynamic data. These data are mapped to a smart-city ontology, called KM4City (Knowledge Model for City), and stored into an RDF-Store where they are available for applications via SPARQL queries to provide new services to the users via specific applications of public administration and enterprises. The paper presents the process adopted to produce the ontology and the big data architecture for the knowledge base feeding on the basis of open and private data, and the mechanisms adopted for the data verification, reconciliation and validation. Some examples about the possible usage of the coherent big data knowledge base produced are also offered and are accessible from the RDF-Store and related services. The article also presented the work performed about reconciliation algorithms and their comparative assessment and selection

    This paper uses case studies, including two cities (Lynn and New Bedford), a sub-city district (Roxbury) and two towns in rural Franklin County (Greenfield and Orange), to examine the role of technology as a potential economic catalyst in rural and depressed places in Massachusetts. Though the five target areas vary in size, density, geographic area, demographic characteristics and economic resources, each exhibits chronic patterns of economic distress related to the decline of manufacturing, construction and other key industries

    Challenges and opportunities to develop a smart city: A case study of Gold Coast, Australia

    Get PDF
    With the rapid growth of information and communication technologies, there is a growing interest in developing smart cities with a focus on the knowledge economy, use of sensors and mobile technologies to plan and manage cities. The proponents argue that these emerging technologies have potential application in efficiently managing the environment and infrastructure, promoting economic development and actively engaging the public, thus contributing to building safe, healthy, sustainable and resilient cities. However, are there other important elements in addition to technologies which can contribute to the creation of smart cities? What are some of the challenges and opportunities for developing a smart city? This paper aims to answer these questions by developing a conceptual framework for smart cities. The framework is then applied to the city of Gold Coast to identify challenges and opportunities for developing the city into a ‘smart city’. Gold Coast is a popular tourist city of about 600,000 populations in South East Queensland, Australia, at the southern end of the 240km long coastal conurbation that is centred by Brisbane. Recently, IBM has nominated Gold Coast as one of the three cities in Australia for its Smarter Cities Challenge Grant. The grant will provide the Gold Coast City Council with the opportunity to collaborate with a group of experts from IBM to develop strategies for enhancing its ICT arrangements for disaster response capabilities. Gold Coast, meanwhile, has potential to diversify its economy from being centred on tourism to a knowledge economy with focus on its educational institutions, investments in cultural precincts and high quality lifestyle amenities. These provide a unique opportunity for building Gold Coast as an important smart city in the region. As part of the research methodology, the paper will review relevant policies of the council. Finally, lessons will be drawn from the case study for other cities which seek to establish themselves as smart cities

    Managing ubiquitous eco cities: the role of urban telecommunication infrastructure networks and convergence technologies

    A successful urban management system for a Ubiquitous Eco City requires an integrated approach. This integration includes bringing together economic, socio-cultural and urban development with a well orchestrated, transparent and open decision making mechanism and necessary infrastructure and technologies. Rapidly developing information and telecommunication technologies and their platforms in the late 20th Century improves urban management and enhances the quality of life and place. Telecommunication technologies provide an important base for monitoring and managing activities over wired, wireless or fibre-optic networks. Particularly technology convergence creates new ways in which the information and telecommunication technologies are used. The 21st Century is an era where information has converged, in which people are able to access a variety of services, including internet and location based services, through multi-functional devices such as mobile phones and provides opportunities in the management of Ubiquitous Eco Cities. This paper discusses the recent developments in telecommunication networks and trends in convergence technologies and their implications on the management of Ubiquitous Eco Cities and how this technological shift is likely to be beneficial in improving the quality of life and place. The paper also introduces recent approaches on urban management systems, such as intelligent urban management systems, that are suitable for Ubiquitous Eco Cities

    Smart Specialisation – Towards a New Generation of Regional Innovation Strategies

    Get PDF
    Inteligentna specjalizacja stała się jednym z zasadniczych wątków współczesnych koncepcji zarządzania rozwojem regionalnym. W oryginale oznacza sztywny podział ról między regiony–liderzy innowacji i pozostałe regiony. Te pierwsze specjalizują się w tzw. technologiach ogólnego zastosowania i/lub ich kombinacji (np. bioinformatyce), drugie zaś w tzw. „koinwencji zastosowań”, czyli w imporcie technologii ogólnego zastosowania i wdrażaniu ich w jednym lub kilku obszarach regionalnej gospodarki. Tego typu koncepcja niesie ze sobą pewne niebezpieczeństwo, bo – jak wynika z doświadczeń międzynarodowych: 1) wysoki poziom innowacyjności wymaga wyrównanego poziomu konkurencyjności kompetencyjnej i technologicznej; 2) szybkość konwergencji konkurencyjności kompetencyjnej jest wyższa niż szybkość konwergencji konkurencyjności technologicznej, czemu również sprzyja dotychczasowy charakter międzynarodowego transferu technologii między liderami innowacji i pozostałymi regionami, ograniczający się (najczęściej) do technologii mniej lub bardziej przestarzałych. Stąd adaptacja koncepcji inteligentnej specjalizacji wymaga od każdego z regionów podwójnego wysiłku: a) znalezienia takich nisz technologicznych, w których mogą osiągnąć rolę lidera innowacji, i tym samym specjalizować się w rozwijaniu technologii ogólnego zastosowania; b) znalezienia takich sektorów / grup pokrewnych sektorów, gdzie mogą się specjalizować we wdrażaniu technologii rozwijanych przez innych liderów innowacji. Procedura określania takich obszarów inteligentnej specjalizacji uwzględnia przewagi konkurencyjne województwa, jego podstawowe zasoby (konkurencyjność technologiczną i konkurencyjność kompetencyjną) i potrzeby modernizacyjne jego bazy społeczno-ekonomicznej oraz globalne uwarunkowania

    The Rise of Innovation Districts: A New Geography of Innovation in America

    Get PDF
    As the United States slowly emerges from the great recession, a remarkable shify is occurring in the spatial geogrpahy of innovation. For the past 50 years, the landscape of innovation has been dominated by places like Silicon Valley - suburban corridors of spatially isolated corporate campuses, accessible only by car, with little emphasis on the quality of life or on integrating work, housing, and recreation. A new complementary urban model is now emerging, giving rise to what we and others are calling "innovation districts." These districts, by our definition, are geographic areas where leading-edge anchor institutions and companies cluster and connect with start-ups, business incubators, and accelerators. They are also physically compact, transit-accessible, and technicall
