Open World Assumption

Typically, relational databases operate under the Closed World Assumption (CWA) of Reiter (Reiter, 1987). The CWA is a meta-rule that says that given a knowledge base KB and a sentence P, if P is not a logical consequence of KB, assume ~P (the negation of P). Thus, we explicitly represent only positive facts in a knowledge base. A negative fact is implicit if its positive counterpart is not present. Under the CWA we presume that our knowledge about the world is complete i.e. there are no “gaps” in our knowledge of the real world. The Open World Assumption (OWA) is the opposite point of view. Here, we “admit” that our knowledge of the real world is incomplete. Thus we store everything we know about the world – positive and negative. Consider a database which simply contains the information “Tweety is a bird”. Assume that we want to ask this database the query “Does Tweety fly?”. Under the CWA, since we assume that there are no gaps in our knowledge, every query returns a yes/no answer. In this case we get the answer “no” because there is no information in the database stating that Tweety can fly. However, under the OWA, the answer to the query is “unknown”. i.e. the database does not know whether Tweety flies or not. We would obtain a “no” answer to this query under the OWA only if it was explicitly stated in the database that Tweety does not fly.

  RESUMO Assentado no pressuposto de que o ser humano se vê na contingência incessante de decidir como agir satisfatoriamente nos multifacetados espaços pelos quais se vê obrigado a circular, defende-se neste texto que a leitura se dá sempre a partir do ambiente em que o indivíduo se encontra, já que as condições do entorno são essenciais para que uma reação adequada à manutenção de sua existência possa ser tomada. Na esteira dessa compreensão, o texto procura demonstrar de que forma a sala de aula, por ter se tornado um ambiente repetitivo e que não dá condições ao sujeito de reagir ao meio, teria perdido o potencial para desenvolver a capacidade leitora das crianças, jovens e adultos que a frequentam. O texto propõe então que histórias em quadrinhos, desde que o trabalho não fique restrito às publicações oriundas da comunicação de massa, podem cumprir essa finalidade, proporcionando aos alunos o contato com obras que ofereçam sempre novos modos de organização do espaço ficcional, chamados de “protocolos de leitura”, que fazem as vezes da chamada leitura de mundo.     Palavras-chave: Leitura. Histórias em quadrinhos. Ensino-aprendizagem.     ABSTRACT   Supposing human beings constantly have to make expected decisions according to social conventions, the following paper is based on the idea that reading must reflect the environment where one lives since the contradictions of such environment are essential for a full life. Thus, it tries to show how classroom activities, as they have become repetitive and do not offer one the conditions to interact with the real world, have lost the potential to develop students’ reading capacity. It suggests that comic books, since the activity is not constrained to popular publications, can show students a new fictional point of view called “reading protocol”, which can be seen as a way of reading the world.     Keywords: Reading.

The article contains a critical analysis of two conceptions of “the nature of things”, as found in publications of West German philosophers of law: G. Radbruch and W. Maihoffer. In the first stage of the evolution of his thought Radbruch spoke of the “influence of the matter on the legal idea”. The function of “the nature of things” is identified by Radbruch with resistance by social reality to the implantation of the legal idea. In the next stage of his views Radbruch conceives of the nature of things as an objective sense of a certain social relationship, perceived from the point of view of a certain value. Now the nature of things serves as a bridge between the real world and the world of values. The nature of things has a minor role according to Radbruch, in legal thought. He emphatically opposes recognizing it as a source of law.

The article considers the development of the ideas of Christian realism as a philosophical and ethical concept of Reinhold Niebuhr. The background of the development of Christian realism’s ideas is described. It is noted that the most impact had Niebuhr’s personal attitude to philosophy and epistemology, as well as the practical experience of serving in Detroit. The methodological approach of Niebuhr is defined as a contrast between the ideal and the real, with the subsequent solving of the conflict between them. It is noted that from the Niebuhr’s point of view, the transforming power of Christianity is rooted in moral and metaphysical dualism, where ethics subordinates metaphysics and gives strength to social and cultural transformations of humanity. It turned out that the ethical concept of Christian realism includes the classification of people as idealists, realists and cynics. Idealists are people who are mainly focused on idealistic concepts that are not represented in the real world. Idealists usually have distorted worldview because they deny taking into account the realities of the world. That also makes them vulnerable to manipulation of cynics. Realists are people who take into account all factors and all known sources of power in the real world, and have a pragmatic position, which is based on moral and ethical qualities. Cynics are those who have a pragmatic position to the world and relations with others, but they guide themselves only by personal interest and egoistic needs, and do not bother with moral restraints. In addition, the relationship of Niebuhr and other neo-orthodoxy theologians is described. Among them there are Karl Barth, Paul Tillich, Emil Brunner and Rudolf Bultmann. The polemic between Niebuhr and Bart is noted. It is shown that the main difference between Bart and Niebuhr was in the theological perspective: for Bart it was mostly dogmatic, and for Niebuhr - ethical and apologetical. The most similar to the theological position of Niebuhr is Brunner's theology, but the differences between them are in relation to the natural law. It is noted that the discrepancy between Niebuhr and Bultmann was an interpretation of the concept of myth. Finally, the contribution of neo-orthodoxy to the development of theology of the twentieth century is considered. It consists of five main achievements: the definition of theology of revelation as a concept of knowledge of God, the rethinking of biblical texts as carriers of kerigma, the historical contextualization of theological tradition, the rethinking of the Reformation’s ideas, and the ecumenical emphasis in theology.

The present communication is primarily nomenclaturial–classical taxonomy is only touched in a side note on a diagnosis. It uses technical terminology coined by Alain Dubois, who is interested in the study of the concepts and theory of biological nomenclature (i.e. the “objective connection between the real world of populations of organisms and the world of language” (Dubois & Ohler 1997)), and who discusses the current ‘International Code for Zoological Nomenclature’ [hereafter just called ‘the Code’] in great detail.

Nikifor Krynicki (Epifaniusz Drowniak, 1895-1968) was one of the most popular non-academic Polish painters worldwide. To show the biblical inspiration in his creative output I chose two categories from various thematic aspects: self-portraits and landscapes with a church. There are plenty of Nikifor’s paintings showing him as a teacher, as a celebrating priest, as a bishop, or even as Christ. A pop­ular way to explain this idea of self-portraits is a psychological one: as a form of auto-therapy. This analysis is aims to show a deeper expla­nation for the biblical anthropology. Nikifor’s self-portraits as a priest celebrating the liturgy are a symbol of creative activity understood as a divine re-creation of the world. Such activity needs divine inspira­tion. Here are two paintings to recall: Potrójny autoportret (The triple self-portrait) and Autoportret w trzech postaciach (Self-portrait in three persons). The proper way to understand the self-identification with Christ needs a reference to biblical anthropology. To achieve our re­al-self we need to identify with Christ, whose death and resurrection bring about our whole humanity. The key impression we may have by showing Nikifor’s landscapes with a church is harmony. The painter used plenty of warm colors. Many of the critics are of the opinion that Nikifor created an imaginary, ideal world in his landscapes, the world he wanted to be there and not the real world. The thesis of this article is that Nikifor created not only the ideal world, but he also showed the source of the harmony – the divine order.

In this paper I will examine the multiple layers of time within Tom Stoppard’s play, Rosencrantz and Guildenstern Are Dead. Typically, a script plays with two definitions of the term: stage time being that of the audience and the “real world,” and dramatic time, the passing of time within the world of the play and the characters’ lives. Rosencrantz and Guildenstern Are Dead is unique in its multitude of times, each occupying its own space within the story. Hamlet resides in a time that extends beyond that of Rosencrantz and Guildenstern Are Dead, while presenting the same story through different characters. When are these stories presented harmoniously, and when can gaps be found between the two plays in terms of time? In contrast, the play‐within‐a‐play presented in Rosencrantz and Guildenstern Are Dead, titled “The Murder of Gonzago,” represents the story even prior to the opening scene of Hamlet and has an omniscient quality, presenting elements of both Hamlet and Rosencrantz and Guildenstern Are Dead. Though this play‐within‐a‐play represents the longest view of the overlapping stories, it is presented in the shortest amount of time. “The Murder of Gonzago” plays with the limitations of time and space and the acknowledgment of their presentation in theatrical terms. Throughout the paper I will determine the overlapping nature of times within the plays, how they are structured around one another, and what this symbolises for both the spaces of each play and the characters within.

This chapter introduces an approach and methods for creating a system that refers to human experiences and thoughts about these experiences in order to ethically evaluate other parties', and in a long run, its own actions. It is shown how applying text mining techniques can enrich machine's knowledge about the real world and how this knowledge could be helpful in the difficult realm of moral relativity. Possibilities of simulating empathy and applying proposed methods to various approaches are introduced together with discussion on the possibility of applying growing knowledge base to artificial agents for particular purposes, from simple housework robots to moral advisors, which could refer to millions of different experiences had by people in various cultures. The experimental results show efficiency improvements when compared to previous research and also discuss the problems with fair evaluation of moral and immoral acts.

Today technology evolves in two different directions. The first one is to create a new technology for our requirement and solve the problem, and the second one is to do it with the existing technology. This chapter will discuss in detail augmented reality and its use in the real world and also its application domains like medicine, education, health, gaming, tourism, film and entertainment, architecture, and development. Many think that AR is only for smartphones, but there are different ways to enhance the insight of the world. Augmented realities can be presented on an extensive range of displays, monitors, screens, handheld devices, or glasses. This chapter will provide the information about the key components of AR devices. This chapter gives a view on different types of AR and also projects how the technology can be adapted for multiple purposes based on the required type of view.

spontaneously invented a name for the creature derived from the most prominent features of its anatomy: kamdopardalis [the normal Greek word for ‘giraffe*]. (10.27.1-4) It is worth spending a little time analysing what is going on in this passage. The first point to note is that an essential piece of information, the creature’s name, is not divulged until the last possible moment, after the description is completed. The information contained in the description itself is not imparted directly by the narrator to the reader. Instead it is chan­ nelled through the perceptions of the onlooking crowd. They have never seen a giraffe before, and the withholding of its name from the reader re-enacts their inability to put a word to what they see. From their point of view the creature is novel and alien: this is conveyed partly by the naive wonderment of the description, and partly by their attempts to control the new phenomenon by fitting it into familiar categories. Hence the comparisons with leopards, camels, lions, swans, ostriches, eyeliner and ships. Eventually they assert conceptual mastery over visual experience by coining a new word to name the animal, derived from the naively observed fea­ tures of its anatomy. However, their neologism is given in Greek (kamdopardalis), although elsewhere Heliodoros is scrupulously naturalistic in observing that Ethiopians speak Ethiopian. The reader is thus made to watch the giraffe from, as it were, inside the skull of a member of the Ethiopian crowd. The narration does not objectively describe what they saw but subjectively re­ enacts their ignorance, their perceptions and processes of thought. This mode of presentation, involving the suppression of an omniscient narrator in direct communication with the reader, has the effect that the reader is made to engage with the material with the same immediacy as the fictional audience within the frame of the story: it becomes, in imagination, as real for him as it is for them. But there is a double game going on, since the reader, as a real person in the real world, differs from the fictional audience inside the novel precisely in that he does know what a giraffe is. This assumption is implicit in the way the description is structured. If Heliodoros* primary aim had been to describe a giraffe for the benefit of an ignorant reader, he would surely have begun with the animal’s name, not withheld it. So for the reader the encounter
