An example of CPSs is the smart city model, which is growing around the prototype of an urban (physical) environment with a new generation of innovative services for transportation, energy distribution, healthcare, environmental monitoring, business, emergency response, and social activities developed in its digital twins. Smart cities are also an example of how CPSs must include the presence of people, which can't be neglected in the loop of producing, collecting and consuming data, information and services. Enabling the technology for such a setting requires a viewpoint of Smart Cities as system of cyber-physical and social systems (CPSSs) which are the result of the integration of several technologies that cooperate to provide seamless services to end users. Such technologies enable the collection, storage, and processing of massive amount of data gathered from the environment and/or produced by citizens themselves. Social interactions amongst participants are promoted as well. CPSS 2019 wants to present innovative research trends and to explore new challenges in the field of smart cities as a system of cyber -- physical systems crossed with the social perspective. The aim of the workshop is to bring together researchers, practitioners, smart city operators and industries working in the field in order to cross-fertilize theoretical and practical aspects.

Even actions as simple as opening doors and windows to ventilate rooms are widely known to be highly effective, and they may be further beneficial if triggered depending on a proper evaluation of indoor air quality levels. However, several online systems currently available on the Web mainly provide theoretical indoor air quality estimations without adequately exploiting IoT-supplied data streams. To tackle such issues, this paper describes a smart service for alerting when the air quality conditions become critical for SARS-COV-2 propagation. It is based on a cyber-physical-social platform, enabled by IoT devices that monitor air quality components, elaborates over the collected samples to infer the risk of SARS-COV-2 propagation. The result of the process alerts enabled users.

In this paper, a cloud-based approach aiming at assessing the QoS in a specific scenario such as the one of Local Transportation Services (LTSs) in Apulia Region (Southern Italy) is proposed. The entire QoS cycle (i.e., design, implementation and monitoring) for smart mobility is addressed, and a supporting platform, exploiting a microservice-based architecture and named UCoMS, is described. In order to validate the pilot case, a set of quality indicators and service levels grounded in European and Italian regulatory frameworks has been considered as well.

In some cases, (e.g., online games, online sensing of sensitive data, etc.) privacy and security issues arise. Peer-to-peer networks can be effectively used to guarantee anonymity and solve the above mentioned issues. In this scenario, we describe an experiment of browser-based peer-to-peer approach for mobile crowdsensing for the specific field of noise pollution monitoring.

The adoption of mobiles as sensing devices (Mobile Crowd Sensing, MCS) and their systematic introduction into curricular activities for improving the learning effectiveness (Bring Your Own Device, BYOD) are two promising approaches that have demonstrated their suitability in the recent years, especially in the didactic of STEM (Science, Technology, Engineering and Math) disciplines. In this paper, we present a MCS- and BYOD-based didactic experience on acoustic sensing for urban environments aiming at improving both the didactic quality on such topics and empowering the active citizenship behavior in youngsters. Such an approach promises to disclose to students novel and effective ways of actively participating in the life of their communities as well as contributing to the improvement of the overall quality of life of their cities. The results achieved so far, have shown a ...

This scenario demands effective ways for modelling CCSs and corresponding Service Level Agreements (SLAs) in order to facilitate service composition, comparison and monitoring. However, current SLA specifications and tools are not well tailored to service composition. In this paper, starting from WSLA, a widely-known SLA description language, we present an extension aimed at modeling contracts and SLAs suitable to support contract owners during service composition and monitoring phases. The proposed WSLA extension is also supported by a tree-graph based tool that can help during SLA and contract composition phases.

In modelling service systems, ontologies have been recognized as a useful instrument for reducing conceptual ambiguities and inconsistencies. However, none of the general approaches proposed in literature have addressed the specific aspects of CCS. In this perspective, we explore how the UFO-S core ontology can be used to describe IT services and, in particular, CCS. A case study and the challenges deriving by CCS are discussed.

To bridge the gap between business and technical requirements and encapsulate business requirements into technical specifications, it can be very convenient to design ETL processes starting from business facts; this would effectively support business users in decision-making processes and would represent business rules and entities as soon as possible in the BI process design. Moreover a fact centered approach to ETL process design can split the traditional black-box approach into several fact-centered flows, which can be processed in parallel exploiting the advantages of distributed multi-threaded process models, typical of big data scenario. In this context we propose a control-flo...

Introduction In previous work, Ferrario and Guarino have proposed an ontological analysis of the notion of service based on the notion of commitment In this approach, a service is understood as a complex process, consisting of several activities going on more or less in parallel, all dependent on a persisting state of generic commitment. More recently , in the framework of a cooperation project involving both LOA and NEMO, such approach has been revised and extended as a specialisation of the UFO ontology (Van Sinderen, et al., 2013). In this work, on one hand, the crucial notion of commitment is complemented by the dual notion of claim, capturing in this way the fundamental relational (contractual) nature of services; on the other hand, both commitments and claims are not understood as states of objects (namely, mental states of service providers or clients), but rather as objects in their own right, although specifically dependent, respectively, on providers or clients. In this...

In this paper, we propose an approach, for enabling universities and schools to develop environmental monitoring experiments based on massive online open labs and citizen science concepts. The approach has been implemented and validated in an educational context, where students participate to scientific research activities. In the paper, we firstly describe the approach to produce successful experiments, the supporting platform and the results achieved in a real context. The effectiveness of the proposed approach is discussed in terms of compliance with a set of reference guidelines addressing the citizen science domain.

Amongst the several pollutant that have to be faced on a daily basis, urban noise represent one of the most widely known for its already ascertained health-related issues. However, no systematic noise management and control activities are performed in the majority of European cities due to a series of limiting factors (e.g., expensive monitoring equipment, few available technician, scarce awareness of the problem in city managers). The recent advances in the Smart City model, which is being progressively adopted in many cities, nowadays offer multiple possibilities to improve the effectiveness in this area. The Mobile Crowd Sensing paradigm allows collecting data streams from smartphone built-in sensors on large geographical scales at no cost and without involving expert data captors, provided that an adequat...

The constantly growing requirements and expectations from several stakeholders, ranging from public authorities, service providers and customers, demand a deep rethinking of the entire system. Such services must be oriented towards sustainability and everyday living, thus needing significant Quality of Service (QoS) improvement in this sector. This paper aims at highlighting the main challenges for modeling and implementing the relationships between the stakeholders in the public transportation sector and proposes a systemic modeling approach that would serve to design, implement, and monitor a QoS-regulatory document. A taxonomy of quality indicators and service levels are proposed along with metrics on the basis of athe European and Italian regulatory background as well as of the public transportation service lifecycle model. The proposed approach has been validated by developing a service analytics system deployed at the regional transportation agency in the Apulia administrative region of Southern Italy.

The opportunities disclosed by smartphones along with their rich outfit of embedded sensors can be exploited according to novel sensing paradigms, as the Mobile Crowd-Sensing (MCS). Moreover, the Bring Your Own Device (BYOD) model promises a capillary diffusion of mobiles in schools, thanks to the extreme pervasiveness these devices have reached amongst youngsters. All these aspects can be leveraged to offer effective laboratorial educational experiences in science. In this paper, we propose a platform that adopts the two paradigms just mentioned for involving secondary schools' students in didactic experimentation about acoustics, which paves the way to the development of a Massive Open Online Laboratory (MOOL) in this scientific sector. The platform design and implementation choices, as well as the didactic experimentation are described throughout the paper.
