Complexity, Governance and the Smart City
The city is today object of scientific interest around the concept of environmental complexity. Its multiformity is an element of richness on which cities base opportunities and raison d'ĂȘtre, thus making it necessary their protection and enhancement, through administrative and managerial actions able to replicate rather than reduce this complex articulation. Yet the inclusive and diffuse management of the vital characters of a city includes explicit or tacit agent/environment relationships. Technology becomes critical support towards intelligent systems for structuring the problems posed by the intricacy, fuzziness and dynamical uncertainty of complex environments -particularly urban settlements. Urban organization becomes a smart city by overcoming prejudices that evoke presumed enhancing mechanisms induced by diffused infrastructuring per se. The cognitive management of the characters and features involved in the formation and organization of the smart city certainly needs adequate architectures, homotetically related to such complexity. An ontology-based approach is proposed here, as an opportunity for analysing and managing this multimensional cognitive assortment, looking for suitable formalization models beyond reductionist smart city commonplaces
Smart city as anti-planning in the UK
This is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this recordCritical commentaries have often treated the smart city as a potentially problematic âtop downâ tendency within policy-making and urban planning, which appears to serve the interests of already powerful corporate and political actors. This article, however, positions the smart city as significant in its implicit rejection of the strong normativity of traditional technologies of planning, in favour of an ontology of efficiency and emergence. It explores a series of prominent UK smart city initiatives (in Bristol, Manchester and Milton Keynes) as bundles of experimental local practices, drawing on the literature pointing to a growing valorisation of the âexperimentalâ over strong policy commitments in urban governance. It departs from this literature, however, by reading contemporary âsmart experimentsâ through Shapin and Schaferâs work on the emergence of 17th-century science, to advance a transhistorical understanding of experimentation as oriented towards societal reordering. From this perspective, the UK smart city merits attention primarily as an indicator of a wider set of shifts in approaches to governance. Its pragmatic orientation sits uneasily alongside ambitions to âstandardiseâ smart and sustainable urban development; and raises questions about the conscious overlap between the stated practical ambitions of smart city initiatives and pre-existing environmental and social policies.This paper was supported by the Economic and Social Research Council (ESRC) [grant number

Ontology-based Classification and Analysis of non- emergency Smart-city Events
Several challenges are faced by citizens of urban centers while dealing with
day-to-day events, and the absence of a centralised reporting mechanism makes
event-reporting and redressal a daunting task. With the push on information
technology to adapt to the needs of smart-cities and integrate urban civic
services, the use of Open311 architecture presents an interesting solution. In
this paper, we present a novel approach that uses an existing Open311 ontology
to classify and report non-emergency city-events, as well as to guide the
citizen to the points of redressal. The use of linked open data and the
semantic model serves to provide contextual meaning and make vast amounts of
content hyper-connected and easily-searchable. Such a one-size-fits-all model
also ensures reusability and effective visualisation and analysis of data
across several cities. By integrating urban services across various civic
bodies, the proposed approach provides a single endpoint to the citizen, which
is imperative for smooth functioning of smart cities
City Data Fusion: Sensor Data Fusion in the Internet of Things
Internet of Things (IoT) has gained substantial attention recently and play a
significant role in smart city application deployments. A number of such smart
city applications depend on sensor fusion capabilities in the cloud from
diverse data sources. We introduce the concept of IoT and present in detail ten
different parameters that govern our sensor data fusion evaluation framework.
We then evaluate the current state-of-the art in sensor data fusion against our
sensor data fusion framework. Our main goal is to examine and survey different
sensor data fusion research efforts based on our evaluation framework. The
major open research issues related to sensor data fusion are also presented.Comment: Accepted to be published in International Journal of Distributed

A study of existing Ontologies in the IoT-domain
Several domains have adopted the increasing use of IoT-based devices to
collect sensor data for generating abstractions and perceptions of the real
world. This sensor data is multi-modal and heterogeneous in nature. This
heterogeneity induces interoperability issues while developing cross-domain
applications, thereby restricting the possibility of reusing sensor data to
develop new applications. As a solution to this, semantic approaches have been
proposed in the literature to tackle problems related to interoperability of
sensor data. Several ontologies have been proposed to handle different aspects
of IoT-based sensor data collection, ranging from discovering the IoT sensors
for data collection to applying reasoning on the collected sensor data for
drawing inferences. In this paper, we survey these existing semantic ontologies
to provide an overview of the recent developments in this field. We highlight
the fundamental ontological concepts (e.g., sensor-capabilities and
context-awareness) required for an IoT-based application, and survey the
existing ontologies which include these concepts. Based on our study, we also
identify the shortcomings of currently available ontologies, which serves as a
stepping stone to state the need for a common unified ontology for the IoT
domain.Comment: Submitted to Elsevier JWS SI on Web semantics for the Internet/Web of

Working Document on Gloss Ontology
This document describes the Gloss Ontology. The ontology and associated class
model are organised into several packages. Section 2 describes each package in
detail, while Section 3 contains a summary of the whole ontology
