Developing an Analytical Framework for Analyzing and Comparing National E-Government Strategies
2020
Part 1: E-Government Foundations; International audience; Across the world, e-government strategies are developed for the effective digitalization of the public sector. They offer governments a framework for dealing with challenges such as technical and legal interoperability and collaboration between public and private sector stakeholders, and for promoting a future vision for a digital public sector. Since e-government strategies are policy document and, thus, likely to convey biased perspectives, analyses of these strategies can yield insights into these biases and different perspectives on public sector digitalization. Until now, there has been no widely recognized framework for systema…
Książę Niccola Machiavellego jako przykład zastosowania toposu zakulisowości
2019
Aby wyjaśnić fenomen popularności Księcia Niccola Machiavellego, należy wskazać na osobliwy sposób komunikowania się autora tego dzieła z czytelnikiem. Autor przedstawia siebie jako fachowca z dziedziny sztuki politycznej, za swoich czytelników zaś chce mieć jedynie tych, którzy, jak on, znają się na rzeczy. Charakterystyczny zimny i, z pozoru przynajmniej, nieozdobny styl, jakim posługuje się autor Księcia, podkreśla dodatkowo profesjonalny i nieosobisty stosunek pisarza do przedmiotu jego rozważań. W kategoriach teorii retorycznej taki sposób komunikowania się daje się opisać jako poszukiwanie okrężnych dróg do tego, co Kenneth Burke określał mianem konsubstancjacji retorycznej. Mówca sta…
Sincerity in Lithuanian epistolarity: Between truth and emotion
2020
AbstractThis paper investigates the lexical representation of sincerity in Lithuanian epistolarity throughout the twentieth century. Drawing on data from the corpus of Lithuanian letters and employing the techniques of corpus, statistical and philological analysis, this paper explores the use, frequency and context of occurrence of the four sets of lexical stems: atvir- (‘open’, ‘frank’), nuošird- (‘sincere’, ‘honest’), šird- (‘heart’), and tikr- (‘authentic’, ‘genuine’, ‘real’). As each of these lexical stems foreground different semantic shades of sincerity, they are treated in this paper as lexical variables that inscribe different degrees of an author’s sincere attitude (stance) toward …
Risks in neural machine translation
2020
Abstract The new paradigm of neural machine translation is leading to profound changes in the translation industry. Surprisingly good results have led to high expectations; however, there are substantial risks that have not yet been sufficiently taken into account. Risks exist on three levels: first, what kind of damage can clients and end users incur in safety-critical domains if the NMT result contains errors; second, who is liable for damage caused by the use of NMT; third, what cyber risks can the use of NMT entail, especially when free online engines are used. When establishing sustainable measures to reduce such risks, we also need to consider general principles of human behaviour if …
A Mission for MARS: The Success of Climate Change Skeptic Rhetoric in the US
2020
Radio and television broadcasters accuse climate scientists of “promoting a global warming hoax”, recommending that they be “named and fi red, drawn and quartered” (Rush Limbaugh); commit “hara kiri” (Glenn Beck); and be “publicly flogged” (Mark Morano). Conservative media are crucial in promoting climate skepticism. Likewise, climate skepticism resonates well with white middle-class men. But why does the middle class continue to support “radical” positions? This article focuses on Anti-Intellectualism to explain why climate skeptic rhetoric resonates with “Middle American Radicals” (MARS).
Generating incremental type services
2019
In this vision paper, we propose a method for generating fully functional incremental type services from declarations of type rules. Our general strategy is to translate type rules into Datalog, for which efficient incremental solvers are already available. However, many aspects of type rules don't naturally translate to Datalog and need non-trivial translation. We demonstrate that such translation may be feasible by outlining the translation rules needed for a language with typing contexts (name binding) and bidirectional type rules (local type inference). We envision that even rich type systems of DSLs can be incrementalized by translation to Datalog in the future.
A New Paradigm in Interactive Evolutionary Multiobjective Optimization
2020
Over the years, scalarization functions have been used to solve multiobjective optimization problems by converting them to one or more single objective optimization problem(s). This study proposes a novel idea of solving multiobjective optimization problems in an interactive manner by using multiple scalarization functions to map vectors in the objective space to a new, so-called preference incorporated space (PIS). In this way, the original problem is converted into a new multiobjective optimization problem with typically fewer objectives in the PIS. This mapping enables a modular incorporation of decision maker’s preferences to convert any evolutionary algorithm to an interactive one, whe…
Multi-class Text Complexity Evaluation via Deep Neural Networks
2019
Automatic Text Complexity Evaluation (ATE) is a natural language processing task which aims to assess texts difficulty taking into account many facets related to complexity. A large number of papers tackle the problem of ATE by means of machine learning algorithms in order to classify texts into complex or simple classes. In this paper, we try to go beyond the methodologies presented so far by introducing a preliminary system based on a deep neural network model whose objective is to classify sentences into more of two classes. Experiments have been carried out on a manually annotated corpus which has been preprocessed in order to make it suitable for the scope of the paper. The results sho…
A Smart Contract Based Recommender System
2019
Nowadays information available on the World Wide Web has reached unprecedented growth and it makes difficult for users to find the most relevant for them. In order to alleviate such issue, Recommender Systems (RSs) have been proposed to collect opinions and preferences about a set of items, process such preferences and build a personalized information access. While the most part of current RSs exploit centralized architecture to provide the service, in this manuscript we propose an alternative approach for building a general purpose RSs that provides to users with more transparent and decentralized rating strategy. Indeed, the proposed framework is built on top of a Distributed Ledger techn…
Eventual Consistency Formalized
2019
Distribution of computation is well-known, and there are several frameworks, including some formal frameworks, that capture distributed computation. As yet, however, models of distributed computation are based on the idea that data is conceptually centralized. That is, they assume that data, even if it is distributed, is consistent. This assumption is not valid for many of the database systems in use today, where consistency is compromised to ensure availability and partition tolerance. Starting with an informal definition of eventual consistency, this paper explores several measures of inconsistency that quantify how far from consistency a system is. These measures capture key aspects of e…
