Automatic detection of accommodation steps as an indicator of knowledge maturing

Jointly working on shared digital artifacts – such as wikis – is a well-tried method of developing knowledge collectively within a group or organization. Our assumption is that such knowledge maturing is an accommodation process that can be measured by taking the writing process itself into account. This paper describes the development of a tool that detects accommodation automatically with the help of machine learning algorithms. We applied a software framework for task detection to the automatic identification of accommodation processes within a wiki. To set up the learning algorithms and test its performance, we conducted an empirical study, in which participants had to contribute to a wiki and, at the same time, identify their own tasks. Two domain experts evaluated the participants’ micro-tasks with regard to accommodation. We then applied an ontology-based task detection approach that identified accommodation with a rate of 79.12%. The potential use of our tool for measuring knowledge maturing online is discussed

Feminism and the Critique of Violence: negotiating feminist political agency

The acute sensitivity of feminism to violence, in its many different forms and contexts, makes it a particularly interesting case for the examination of the relationship between politics and violence in theory and practice. Our purpose in this paper is not to adjudicate the normative question of whether feminism implies a commitment to pacifism or to the use of non-violence. Rather, we are interested in examining how the relation between feminist politics and violence is construed as feminists struggle to develop a politics in which opposition to patriarchal violence is central. We begin with the feminist critique of violence, and move to examine how particular articulations of that critique shape and are shaped by practices of feminist political agency in specific contestation over the goals and strategies of feminism. We use the well-known case of feminist debates over the Greenham Common Peace Camp in the UK in the 1980s to demonstrate how negotiating women's political agency in relation to opposition to male violence poses problems, both for feminists who embrace non-violence and prioritize the opposition to war, and for feminists who are suspicious of non-violence and of the association of feminism with peace activism. In both cases, the debates over Greenham demonstrate the fundamentally political character of the ways in which the relation and distinction between violence and politics are conceptually and practically negotiated

RDF Knowledge Graph Visualization From a Knowledge Extraction System

In this paper, we present a system to visualize RDF knowledge graphs. These graphs are obtained from a knowledge extraction system designed by GEOLSemantics. This extraction is performed using natural language processing and trigger detection. The user can visualize subgraphs by selecting some ontology features like concepts or individuals. The system is also multilingual, with the use of the annotated ontology in English, French, Arabic and Chinese

An argument against the realistic interpretation of the wave function

Testable predictions of quantum mechanics are invariant under time reversal. But the change of the quantum state in time is not so, neither in the collapse nor in the no-collapse interpretations of the theory. This fact challenges the realistic interpretation of the quantum state. On the other hand, this fact follows easily if we interpret the quantum state as a mere calculation device, bookkeeping past real quantum events. The same conclusion follows from the analysis of the meaning of the wave function in the semiclassical regime.Comment: 4 pages, 3 figure

Events, processes, and the time of a killing

The paper proposes a novel solution to the problem of the time of a killing (ToK), which persistently besets theories of act-individuation. The solution proposed claims to expose a crucial wrong-headed assumption in the debate, according to which ToK is essentially a problem of locating some event that corresponds to the killing. The alternative proposal put forward here turns on recognizing a separate category of dynamic occurents, viz. processes. The paper does not aim to mount a comprehensive defense of process ontology, relying instead on extant defenses. The primary aim is rather to put process ontology to work in diagnosing the current state of play over ToK, and indeed in solving it

A linguistically-driven methodology for detecting impending and unfolding emergencies from social media messages

Natural disasters have demonstrated the crucial role of social media before, during and after emergencies (Haddow & Haddow 2013). Within our EU project Sland \ub4 ail, we aim to ethically improve \ub4 the use of social media in enhancing the response of disaster-related agen-cies. To this end, we have collected corpora of social and formal media to study newsroom communication of emergency management organisations in English and Italian. Currently, emergency management agencies in English-speaking countries use social media in different measure and different degrees, whereas Italian National Protezione Civile only uses Twitter at the moment. Our method is developed with a view to identifying communicative strategies and detecting sentiment in order to distinguish warnings from actual disasters and major from minor disasters. Our linguistic analysis uses humans to classify alert/warning messages or emer-gency response and mitigation ones based on the terminology used and the sentiment expressed. Results of linguistic analysis are then used to train an application by tagging messages and detecting disaster- and/or emergency-related terminology and emotive language to simulate human rating and forward information to an emergency management system

PERFORMATIVITY, SOCIAL ONTOLOGY, AND THE USES OF NARRATIVES IN LATIN AMERICA

ABSTRACT: This article explains the relationship between performativity and social ontology in the case of Latin American narratives of resistance and liberation. In particular, it shows how these narratives construct social facts and provide social reality to experiences of oppression and to efforts of resistance and liberation, by means of performative functions tied to the creation and maintenance of social ontologies and to the struggle for identity, social recognition, sources of legitimacy, and hegemony. Latin America is not singular in the use of these kinds of narratives but it is special in the centrality that it gives to them and in its awareness of it. By way of example, the article touches upon four narratives that displa
