Sub-symbolic Mapping of Cyc Microtheories in Data-Driven “Conceptual” Spaces

2007

The presented work aims to combine statistical and cognitive-oriented approaches with symbolic ones so that a conceptual similarity relationship layer can be added to a Cyc KB microtheory. Given a specific microtheory, a LSA-inspired conceptual space is inferred from a corpus of texts created using both ad hoc extracted pages from the Wikipedia repository and the built-in comments about the concepts of the specific Cyc microtheory. Each concept is projected in the conceptual space and the desired layer of subsymbolic relationships between concepts is created. This procedure can help a user in finding the concepts that are "sub-symbolically conceptually related" to a new concept that he want…

Exploring the Role of Informants in Interpretive Case Study Research in IS

2011

Interpretive case study research constitutes an important and increasing part of the information systems (IS) knowledge base (Walsham, 1993; Myers, 1997; Pare and Elam, 1997; Walsham, 2006). Interpretive case studies can be distinguished from positivist case study research (Benbasat et al., 1987; Lee, 1989; Dube and Pare, 2003) by the focus on close interaction between researcher and participants throughout the case study process, viewing the case members as active participants in the construction of the case narrative (Boland, 1985; Guba and Lincoln, 1989; Kvale, 2002). However, while the interpretivist perspective ascribes an active role to the case study informants, in practice the exten…

On marrying ontological and metamodeling technical spaces

2007

In software engineering, the use of models and metamodeling approaches (e.g., MDA with MOF/UML) for purposes such as software design or software validation is an established practice. Ontologies constitute domain models formalized using expressive logic languages for class definitions and rules. Hence, when seen from an abstract point of view, the two paradigms and their various technological spaces seem closely related. However, in the state-of-the-art research and practice the two technologies are just beginning to converge and the relationship between the two is still under exploration. In this paper, we give an outline of current ontology technologies, such as the Semantic Web standards…

Research production in high-impact journals of contemporary neuroscience: A gender analysis

2017

Neuroscience or Neural Science is a very active and interdisciplinary field that seeks to understand the brain and the nervous system. In spite of important advances made in recent decades, women are still underrepresented in neuroscience research output as a consequence of gender inequality in science overall. This study carries out a scientometric analysis of the 30 neuroscience journals (2009–2010) with the highest impact in the Web of Science database (Thomson Reuters) in order to quantitatively examine the current contribution of women in neuroscientific production, their pattern of research collaboration, scientific content, and the analysis of scientific impact from a gender perspect…

Terrain data compression using wavelet-tiled pyramids for online 3D terrain visualization

2013

Last years have witnessed the widespread use of online terrain visualization applications. However, the significant improvements achieved in sensing technologies have allowed an increasing size of the terrain databases. These increasing sizes represent a serious drawback when terrain data must be transmitted and rendered at interactive rates. In this paper, we propose a novel wavelet-tiled pyramid for compressing terrain data that replaces the traditional multiresolution pyramid usually used in wavelet compression schemes. The new wavelet-tiled pyramid modifies the wavelet analysis and synthesis processes, allowing an efficient transmission and reconstruction of terrain data in those applic…

Understanding TwitterTM Use among Parliament Representatives: A Genre Analysis

2011

Published version of a chapter published in the book: Electronic Participation. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-23333-3_1 This article examines parliament representatives’ Twitter- contributions (tweets). First, the genre of communication approach is introduced to identify common characteristics and communication patterns. Second, the findings are analysed using various eDemocracy models and deliberative standards to identify to what extent these tweets could be characterized as part of a deliberative discussion. The tweets are mainly dominated by five communication purposes; providing links to information sources for other Twitter users, to inform …

Key drivers of internet banking services use

2009

PurposeThe purpose of this paper is to analyse the determinants of internet banking use, paying special attention to the role of product involvement, perceived risk and trust.Design/methodology/approachThe impact of trust, perceived risks, product involvement and TAM beliefs (ease of use and usefulness) on internet banking adoption is tested through structural equation modelling techniques. The sample consists of 511 Spanish internet banking services users and the data are collected through an internet survey. Risk is measured as a formative construct.FindingsData analysis shows that TAM beliefs and perceived risks (security, privacy, performance and social) have a direct influence on e‐ban…

Kerr Combs and Telecommunications Components for the Generation and High-Dimensional Quantum Processing of d-Level Cluster States

2019

Large and complex optical quantum states are a key resource for fundamental science and applications such as quantum communications, information processing, and metrology. In this context, cluster states are a particularly important class because they enable the realization of universal quantum computers by means of the so-called ‘one-way’ scheme, where processing operations are performed through measurements on the state. While two-level (i.e. qubit) cluster states have been realized thus far, further boosting this computational resource by increasing the number of particles comes at the price of significantly reduced coherence time and detection rates, as well as increased sensitivity to …

Genres of participation in social networking systems: A study of the 2009 Norwegian parliamentary election

2010

Published version of a chapter in the book: Electronic Participation. Also available at http://dx.doi.org/10.1007/978-3-642-15158-3_9 In the Norwegian context, eParticipation in the form of online campaigning has been on the agenda since 2001. After Obama’s successful presidential campaign in 2008, expectations about the use of SNS in the Norwegian parliamentary election were high. This study explores genres of participation in the early stages of the 2009 Norwegian parliamentary election campaign. The main finding is that the political parties have seen the need for a presence in SNS’, and that a genre repertoire for political communication through SNS is beginning to evolve. However, ther…
