Unfortunately when addressing the wider public, like in schools, museums and cultural spaces, history is often presented in a simplistic, siloed and localistic manner that promotes memorizing rather than understanding, does not account for cross-border cultural aspects and prevents historical events from being viewed as a shared, global experience. The goal of the CrossCult H2020 project, comprising 11 partners from 7 European countries, is to spur a change in the way European citizens appraise, interpret and access history, by enabling new and highlighting existing cross-border connections among pieces of cultural heritage, other citizens' viewpoints and physical venues. Facilitated by technology and mobile applications, with a strong backg...

In CPSS users co-exist with different stakeholders influencing each other while being influenced by different environmental factors. Additionally, these environments often have their own desired goals and corresponding set of rules in place expecting people to behave in certain ways. Hence, in such settings classical approaches to personalisation which solely optimise for user satisfaction are often encumbered by competing objectives and environmental constraints which are yet to be addressed jointly. In this work we set out to (i) formalise the general problem of personalisation in CPSS from a multi-stakeholder perspective taking into account the full environmental complexity, (ii) extend the general formalisation to the case of exhibition areas and propose a personalised Multi-stakeholder aware Recommen...

This paradigm shift from CPS to CPSS was mainly attributed to the increasing use of sensor enabled smart devices and the tight link with the users. The concept of CPSS has been around for over a decade and it has gained an increasing attention over the past few years. The evolution to incorporate human aspects in the CPS research has unlocked a number of research challenges. Particularly human dynamics brings additional complexity that is yet to be explored. The exploration to conceptualise the notion of CPSS has been partially addressed in few scientific literatures. Although its conceptualisation has always been use-case dependent. Thus, there is a lack of generic view as most works focus on specific domains. Furthermore the systemic core and design principles linking it with the theory of syst...

Hence, they influence the quality of recommendations. Specifically, in Visual Art (VA) recommendations the complexity of the concepts embodied within paintings, makes the task of capturing semantics by machines far from trivial. In VA recommendation, prominent works commonly use manually curated metadata to drive recommendations. Recent works in this domain aim at leveraging visual features extracted using Deep Neural Networks (DNN). However, such data representation approaches are resource demanding and do not have a direct interpretation, hindering user acceptance. To address these limitations, we introduce an approach for Personalised Recommendation of Visual arts based on learning latent semantic representation of paintings. Specifically, we trained a Latent Dirichlet Allocation (LDA) model on textual descripti...

However, human interaction behaviour is the result of multiple social dimensions governed by complex environmental, cultural and contextual factors which are not yet fully understood. Additionally, works in this direction still lack a well established systemic foundation. Thus, handling properly the social factor in Human-CPS interaction remains an open challenge. In this paper, we present a new perspective and a formalisation for the CPSS paradigm, which is grounded on the theory of systems. The aim of this is to provide a general framework to handle social dimensions in Human-CPS interactions. We propose a meta-model, which provides a conceptual ground to design CPSS spaces where CPS are enhanced with social capabilities.

Advances in manufacturing and automation industries created hyper-connected industrial ecosystems that are not limited to smart production but also facilitate organizational integration. Hence, fostering the creation of collaborative, networked and intelligent industries. One of the emerging advances in the digital transformation of industries is the creation of environments where humans work in close collaboration with sensor enabled smart machines and robots. Particularly the close involvement of humans in such smart environments challenges system designed methodologies mainly because human aspects are not considered in CPS design frameworks. In this paper, we present an approach to support this aspect of Industry 4.0 taking a Cyber-Physical-Social System (CPSS) paradigm to incorporate human aspects ...

Changes to products and services and to supply network configurations occur frequently and require to maintain interoperability constantly in a dynamic way. Designed to formalize and handle interoperability issues, the Ontology of Enterprise Interoperability lacks means to capture the dynamics of modern business. We propose in this paper an extension based on the Complex Adaptive Systems theory. A use-cases is discussed by applying the ontology within a knowledge life cycle framework.
