Abstract:
The Dempster–Shafer evidence theory has been widely used in the field of data fusion. However, with further research, incomplete information under the open world assumption has been discovered as a new type of uncertain information. The classical Dempster’s combination rules are difficult to solve the related problems of incomplete information under the open world assumption. At the same time, partial information entropy, such as the Deng entropy is also not applicable to deal with problems under the open world assumption. Therefore, this paper proposes a new method framework to process uncert

Abstract:
Quantifying uncertainty is a hot topic for uncertain information processing in the framework of evidence theory, but there is limited research on belief entropy in the open world assumption. In this paper, an uncertainty measurement method that is based on Deng entropy, named Open Deng entropy (ODE), is proposed. In the open world assumption, the frame of discernment (FOD) may be incomplete, and ODE can reasonably and effectively quantify uncertain incomplete information. On the basis of Deng entropy, the ODE adopts the mass value of the empty set, the cardinality of FOD, and the natural const

This article differentiates two ways of understanding family diversity— objectively and interpretively. The search for objective diversity is rooted in the assumption that there are many different kinds of families in the United States and around the world; the search for interpretive diversity is rooted in the assumption that any given “family” may be described in different, often contradictory ways. These divergent assumptions can lead relatively objective or interpretive scholars to produce divergent analyses, even as they use seemingly identical concepts to address similar explanatory conc

Abstract:
In many data-centric semantic web applications, it is desirable to use OWL to encode the Integrity Constraints (IC) that must be satisfied by instance data. However, challenges arise due to the Open World Assumption (OWA) and the lack of a Unique Name Assumption (UNA) in OWL’s standard semantics. In particular, conditions that trigger constraint violations in systems using the ClosedWorld Assumption (CWA), will generate new inferences in standard OWL-based reasoning applications. In this paper, we present an alternative IC semantics for OWL that allows applications to work with the CWA and the

Abstract:
Real-world decisions are often open ended, with goals, choice options, or evaluation criteria conceived by decision-makers themselves. Critically, the quality of decisions may heavily rely on the generation of options, as failure to generate promising options limits, or even eliminates, the opportunity for choosing them. This core aspect of problem structuring, however, is largely absent from classical models of decision-making, thereby restricting their predictive scope. Here, we take a step toward addressing this issue by developing a neurally inspired cognitive model of a class of ill-struc

Full text
Abstract:
AbstractEffective collaboration of embedded systems relies strongly on the assumption that all components of the system and the system itself operate as expected. A level of trust is established based on that assumption. To verify and validate these assumptions, we propose a systematic procedure that starts at the design phase and spans the runtime of the systems. At design time, we propose system evaluation in pure virtual environments, allowing multiple system behaviors to be executed in a variety of scenarios. At runtime, we suggest performing predictive simulation to get insights into the system’s decisionmaking process. This enables trust to be created in the system part of a cooperation. When cooperation is performed in open, uncertain environments, the negotiation protocols between collaborative systems must be monitored at runtime. By engaging in various negotiation protocols, the participants assign roles, schedule tasks, and combine their world views to allow more resilient perception and planning. In this chapter, we describe two complementary monitoring approaches to address the decentralized nature of collaborative embedded systems.

Abstract:
AbstractThe geopolitical dialogue about technology has, for a quarter of a century, essentially revolved around a single technological ecosystem built by the American private sector. An assumption took hold that, over time, clearer “rules of the road” for this digital domain would take hold. But progress toward this has been surprisingly slow; we sometimes refer to “grey zone” activity, because the rules, insofar as they exist, are fuzzy.In the meantime, the digital climate is changing. China’s technological ambitions are not to compete on the American-built, free, open Internet, but to design and build a completely new, more authoritarian system to supplant it. This is forcing a bifurcation of the Internet, and organizations like the European Union and countries across the world have to rethink whether the regulation of American technology is really where the focus should be, rather than working with the USA to contest China’s ambitions.

Full text
Abstract:
AbstractDespite having one of the largest diaspora in the world, the United Kingdom peculiarly has no diaspora engagement policy to speak of. Policy, not legal right, underpins consular affairs and social protection policies are extremely limited. Such absence stems from a lack of distinctive British national identity in large part due to the UK being multi-national state, a heterogonous and typically prosperous diaspora driven by lifestyle migration, and in turn the assumption that Britons living abroad do not want or need to engage with the homeland state. Policy towards Britons residing abroad is characterised by limited engagement but effective communication leading to a disengaged state that keeps the dialogue open. Whilst social protection policies are rudimentary, the state is a world leader in providing online information in preparing British emigrants for living overseas. Voting rights of overseas citizens (namely the 15 year residency requirement) has and will continue to be a contentious issue following Brexit − and one subject to change − as has pension inflation adjustment. As the effects of Brexit on Britons residing abroad come to fruition, the politics of social protection and the rights of Britons residing abroad will be an imperative issue on the political agenda.

Full text
Abstract:
AbstractSemantic segmentation is a crucial component for perception in automated driving. Deep neural networks (DNNs) are commonly used for this task, and they are usually trained on a closed set of object classes appearing in a closed operational domain. However, this is in contrast to the open world assumption in automated driving that DNNs are deployed to. Therefore, DNNs necessarily face data that they have never encountered previously, also known as anomalies, which are extremely safety-critical to properly cope with. In this chapter, we first give an overview about anomalies from an information-theoretic perspective. Next, we review research in detecting unknown objects in semantic segmentation. We present a method outperforming recent approaches by training for high entropy responses on anomalous objects, which is in line with our theoretical findings. Finally, we propose a method to assess the occurrence frequency of anomalies in order to select anomaly types to include into a model’s set of semantic categories. We demonstrate that those anomalies can then be learned in an unsupervised fashion which is particularly suitable in online applications.

Full text
Abstract:
AbstractBased on the assumption that globalization should not imply homogenization, it is important for education to promote dialogue and intercultural understanding. The first appearance of the term ‘intercultural education’ in Europe dates back to 1983, when European ministers of education at a conference in Berlin, in a resolution for the schooling of migrant children, highlighted the intercultural dimension of education (Portera in Intercultural Education 19:481–491, 2008). One of the mandates of intercultural education is to promote intercultural dialogue, meaning dialogue that is “open and respectful” and that takes place between individuals or groups “with different ethnic, cultural, religious and linguistic backgrounds and heritage on the basis of mutual understanding and respect” (Council of Europe in White paper on intercultural dialogue: Living together as equals in dignity. Council of Europe, Strasbourg, p. 10, 2008). Such backgrounds and heritages form cultural identities, not limited to ethnic, religious and linguistic ones, as culture is a broader concept including several layers such as “experience, interest, orientation to the world, values, dispositions, sensibilities, social languages, and discourses” (Cope and Kalantzis in Pedagogies: An International Journal 4:173, 2009). As cultural identities are multi-layered, so is cultural diversity, and therefore it becomes a challenge for educators and researchers to address it (Hepple et al. in Teaching and Teacher Education 66:273–281, 2017). Referring to Leclercq (The lessons of thirty years of European co-operation for intercultural education, Steering Committee for Education, Strasbourg, 2002), Hajisoteriou and Angelides (International Journal of Inclusive Education 21:367, 2017) argue that “intercultural education aims to stress the dynamic nature of cultural diversity as an unstable mixture of sameness and otherness.” This challenge relates to the dynamic concept of culture itself, as socially constructed, and continuously shaped and reshaped through communicative interactions (Holmes et al. in Intercultural Education 26:16–30, 2015).

Abstract:
AbstractOur chapter builds upon feminist understandings of the more-than-human, using our experiences of working with peasant farmers involved in seed saving (Leila) and activists’ relation to individual environmental practices (Karijn). Through a dialogue around our experiences, we reflect on feelings of discomfort, and how, rather than resolving our anxieties, discomfort has the potential to open up conventional ways of being a researcher. Focusing on relationality through embodied and processual research challenges the notion of method as a tool used by a disembodied researcher observing an inert or external world, a central concern of feminist-oriented research. We show how participating in plural and more-than-human worlds also challenges multiple binary positionings and allows for unwarranted surprises that might undo the assumptions and categories underpinning our research.

While intuitive, these semantics are not sufficiently precise to give reasonable answers to queries. We propose overcoming these is

Abstract:
Infrastructure in the cloud is deployed through configuration files, which specify the resources to be created, their settings, and their connectivity. We aim to model infrastructure before deployment and reason about it so that potential vulnerabilities can be discovered and security best practices enforced. Description logics are a good match for such modeling efforts and allow for a succinct and natural description of cloud infrastructure. Their open-world assumption allows capturing the distributed nature of the cloud, where a newly deployed infrastructure could connect to pre-existing res

Abstract:
Existential rules generalize Datalog with existential quantification in the head. Natively, Datalog is interpreted under a closed-world semantics, while existential rules typically employ the open-world assumption. The interpretation domain in the latter case is enlarged by infinitely many "anonymous" individuals. Then, in any rule, each variable ranges over all individuals, even if not needed or required. In this paper, we enhance existential rules by closed-world variables to consciously reason on the properties of "known" (non-anonymous) and arbitrary individuals in different ways. Accordin

Abstract:
This paper proposes a framework for building product information model (PIM) and product rule model (PRM), and integrated reasoning based on Description Frame Logic (DFL) [1] for collaborative product engineering environments. Most of the previous research has focused either on building ontology for PIM or on building a rule base for PRM respectively, not on both of them. Some research on product engineering has tried to build both ontology language and rule-language. But, the research is/has been limited to using both languages in a homogeneous approach under open world assumption (OWA) such

Abstract:
The reliance on concepts derived from observations in laboratories combined with the assumption that concepts and behavior are one-to-one (monism) have impeded the development of social science, machine learning (ML) and belief logics by restricting them to operate in controlled and stable contexts. Even in open contexts, using ideas developed in laboratories, despite using well-trained observers to make predictions about the likelihood of outcomes in open contexts, using the same concepts and assumptions, in 2016, Tetlock and Gardner's "superforecasters" failed to predict Brexit (Britain’s ex

Full text
Abstract:
In Ontology-Based Data Access (OBDA), user queries are evaluated over a set of facts under the open world assumption, while taking into account background knowledge given in the form of a Description Logic (DL) ontology. Motivated by situation awareness applications, temporal conjunctive queries (TCQs) have recently been proposed as a useful extension of traditional OBDA to support the processing of temporal information. This paper extends the existing complexity analysis of TCQ entailment to very expressive DLs underlying the OWL 2 standard, and in contrast to previous work also allows for qu

Abstract:
Ontology-based query answering augments classical query answering in databases by adopting the open-world assumption and by including domain knowledge provided by an ontology. We investigate temporal query answering w.r.t. ontologies formulated in DL-Lite, a family of description logics that captures the conceptual features of relational databases and was tailored for efficient query answering. We consider a recently proposed temporal query language that combines conjunctive queries with the operators of propositional linear temporal logic (LTL). In particular, we consider negation in the onto

Ontology-based data access augments classical query answering over fact bases by adopting the open-world assumption and by including domain knowledge provided by an ontology. We implemented temporal query answering w.r.t. ontologies formulated in the Description Logic DL-Lite. Focusing on temporal conjunctive queries (TCQs), which combine conjunctive queries via the operators of propositional linear temporal logic, we regard three approaches for answering them: an iterative algorithm that considers all data available; a window-based algorithm; and a rewriting approach, which translates the TCQ

Abstract:
This paper studies the effect of demographic transitions on the economy of Latin America and the Caribbean (LAC). The paper builds a model of multi-regions of the world and derives the path of macroeconomic variables including aggregate output, capital, labor and the saving rate as economies face a rapid shift in demographics. The timing and the extent of the demographic transition differ across regions. The model is simulated under both closed economy and open economy assumptions to quantify the roles played by factor mobility across regions in shaping capital accumulation and equilibrium fac

Abstract:
This study deals with the appropriate macroeconomic policies toward international capital flows. It argues that countries in a position to integrate themselves into world capital markets should develop specific policies to deal with capital flows. This paper first shows that foreign capital inflows are not only larger and more volatile but also that their effects on key macroeconomic variables are much stronger in emerging developing countries than in developed countries. Next, the two opposing paradigms regarding capital flows are discussed in detail. Then, a simple classical open economy mac

Abstract:
COVID-19, caused by the SARS-CoV-2 virus, was first reported in China in December 2019. The virus has spread rapidly around the world and is currently responsible for 500 million reported cases and over 6.4 million deaths. A risk assessment published by the Foods Standards Agency (FSA) in 2020 (Opens in a new window) concluded that it was very unlikely that you could catch coronavirus via food. This assessment included the worst-case assumption that, if food became contaminated during production, no significant inactivation of virus would occur before consumption.
