Análisis de la web semántica: estado actual y requisitos futuros

The vast and growing number of web resources show that lexical-statistical aids by themselves cannot resolve the problem of information retrieval. The "semantic web" project tries to solve these problems (and to do much more) by having the computers comprehend the content of the resources. This paper examines the current status of the required 'la-yers' put forward by Berners-Lee for the development of the Semantic web: namely, the uniform identification layer, the representation layer, the logical layer, and the security layer

Engines of Order

Over the last decades, and in particular since the widespread adoption of the Internet, encounters with algorithmic procedures for ‘information retrieval’ – the activity of getting some piece of information out of a col-lection or repository of some kind – have become everyday experiences for most people in large parts of the world

Integrative Levels of Knowing

Diese Dissertation beschäftigt sich mit einer systematischen Organisation der epistemologischen Dimension des menschlichen Wissens in Bezug auf Perspektiven und Methoden. Insbesondere wird untersucht inwieweit das bekannte Organisationsprinzip der integrativen Ebenen, das eine Hierarchie zunehmender Komplexität und Integration beschreibt, geeignet ist für eine grundlegende Klassifikation von Perspektiven bzw. epistemischen Bezugsrahmen. Die zentrale These dieser Dissertation geht davon aus, dass eine angemessene Analyse solcher epistemischen Kontexte in der Lage sein sollte, unterschiedliche oder gar konfligierende Bezugsrahmen anhand von kontextübergreifenden Standards und Kriterien vergleichen und bewerten zu können. Diese Aufgabe erfordert theoretische und methodologische Grundlagen, welche die Beschränkungen eines radikalen Kontextualismus vermeiden, insbesondere die ihm innewohnende Gefahr einer Fragmentierung des Wissens aufgrund der angeblichen Inkommensurabilität epistemischer Kontexte. Basierend auf Jürgen Habermas‘ Theorie des kommunikativen Handelns und seiner Methodologie des hermeneutischen Rekonstruktionismus, wird argumentiert, dass epistemischer Pluralismus nicht zwangsläufig zu epistemischem Relativismus führen muss und dass eine systematische Organisation der Perspektivenvielfalt von bereits existierenden Modellen zur kognitiven Entwicklung profitieren kann, wie sie etwa in der Psychologie oder den Sozial- und Kulturwissenschaften rekonstruiert werden. Der vorgestellte Ansatz versteht sich als ein Beitrag zur multi-perspektivischen Wissensorganisation, der sowohl neue analytische Werkzeuge für kulturvergleichende Betrachtungen von Wissensorganisationssystemen bereitstellt als auch neue Organisationsprinzipien vorstellt für eine Kontexterschließung, die dazu beitragen kann die Ausdrucksstärke bereits vorhandener Dokumentationssprachen zu erhöhen. Zudem enthält der Anhang eine umfangreiche Zusammenstellung von Modellen integrativer Wissensebenen.This dissertation is concerned with a systematic organization of the epistemological dimension of human knowledge in terms of viewpoints and methods. In particular, it will be explored to what extent the well-known organizing principle of integrative levels that presents a developmental hierarchy of complexity and integration can be applied for a basic classification of viewpoints or epistemic outlooks. The central thesis pursued in this investigation is that an adequate analysis of such epistemic contexts requires tools that allow to compare and evaluate divergent or even conflicting frames of reference according to context-transcending standards and criteria. This task demands a theoretical and methodological foundation that avoids the limitation of radical contextualism and its inherent threat of a fragmentation of knowledge due to the alleged incommensurability of the underlying frames of reference. Based on Jürgen Habermas’s Theory of Communicative Action and his methodology of hermeneutic reconstructionism, it will be argued that epistemic pluralism does not necessarily imply epistemic relativism and that a systematic organization of the multiplicity of perspectives can benefit from already existing models of cognitive development as reconstructed in research fields like psychology, social sciences, and humanities. The proposed cognitive-developmental approach to knowledge organization aims to contribute to a multi-perspective knowledge organization by offering both analytical tools for cross-cultural comparisons of knowledge organization systems (e.g., Seven Epitomes and Dewey Decimal Classification) and organizing principles for context representation that help to improve the expressiveness of existing documentary languages (e.g., Integrative Levels Classification). Additionally, the appendix includes an extensive compilation of conceptions and models of Integrative Levels of Knowing from a broad multidisciplinary field

What is 'digital literacy'? A Pragmatic investigation.

Digital literacy has been an increasingly-debated and discussed topic since the publication of Paul Gilster’s seminal Digital Literacy in 1997. It is, however, a complex term predicated on previous work in new literacies such as information literacy and computer literacy. To make sense of this complexity and uncertainty I come up with a ‘continuum of ambiguity’ and employ a Pragmatic methodology. This thesis makes three main contributions to the research area. First, I argue that considering a plurality of digital literacies helps avoid some of the problems of endlessly-redefining ‘digital literacy’. Second, I abstract eight essential elements of digital literacies from the research literature which can lead to positive action. Finally, I argue that co-constructing a definition of digital literacies (using the eight essential elements as a guide) is at least as important as the outcome

Unmet goals of tracking: within-track heterogeneity of students' expectations for

Educational systems are often characterized by some form(s) of ability grouping, like tracking. Although substantial variation in the implementation of these practices exists, it is always the aim to improve teaching efficiency by creating homogeneous groups of students in terms of capabilities and performances as well as expected pathways. If students’ expected pathways (university, graduate school, or working) are in line with the goals of tracking, one might presume that these expectations are rather homogeneous within tracks and heterogeneous between tracks. In Flanders (the northern region of Belgium), the educational system consists of four tracks. Many students start out in the most prestigious, academic track. If they fail to gain the necessary credentials, they move to the less esteemed technical and vocational tracks. Therefore, the educational system has been called a 'cascade system'. We presume that this cascade system creates homogeneous expectations in the academic track, though heterogeneous expectations in the technical and vocational tracks. We use data from the International Study of City Youth (ISCY), gathered during the 2013-2014 school year from 2354 pupils of the tenth grade across 30 secondary schools in the city of Ghent, Flanders. Preliminary results suggest that the technical and vocational tracks show more heterogeneity in student’s expectations than the academic track. If tracking does not fulfill the desired goals in some tracks, tracking practices should be questioned as tracking occurs along social and ethnic lines, causing social inequality

The effects of race

CITATION: Jablonski, N. G. & Mare, G. (eds) 2018. The effects of race. Stellenbosch: SUN PReSS, doi:10.18820/9781928357858.The original publication is available at https://africansunmedia.store.it.si/zaThe STIAS research theme on Being Human Today explores the interrelated questions: What does it mean to be human? And: What is the nature of the world in which we aspire to be human? In the context of post-apartheid South Africa race and racism remain key references in both these questions. Why is this so, considering that the biological basis of race thinking has been refuted? Templates of race and racialism remain at the core of state policy in South Africa, periodic gross incidents of racism surface in public, and notions of the existence of races remain central to everyday thinking and discourse. This book is the result of the work of a group of leading thinkers and their in-depth conversations at STIAS during the winter of 2015 on the effects of race. Convened by evolutionary anthropologist Nina Jablonski and sociologist Gerhard Maré, the group included Njabulo Ndebele, Chabani Manganyi, Barney Pityana, Crain Soudien, Göran Therborn, Mikael Hjerm, Zimitri Erasmus and George Chaplin. The group reconvened annually through 2017. This is the first in a series of planned publications on the their work.An Introduction / Nina G.
