In this chapter, we advance, from the point of view of Knowledge Representation and Reasoning, an analysis of which ontological dimensions are needed to develop Mobile Web 2.0 on top of Semantic Web. This analysis will be particularly focused on social networks and it will try to make an outlook about the new knowledge challenges on this field. Some of these new challenges will be linked to Semantic Web context, while others will be inherent to Semantic Mobile Web 2.0.

Tools And Techniques

The ISO/HL7 27931:2009 standard intends to establish a global interoperability framework for healthcare applications. However, being a messaging related protocol, it lacks a semantic foundation for interoperability at a machine treatable level intended through the Semantic Web. There is no alignment between the HL7 V2.xml message payloads and a meaning service like a suitable ontology. Careful application of Semantic Web tools and concepts can ease the path to the fundamental concept of Shared Semantics. In this chapter, the Semantic Web and Artificial Intelligence tools and techniques that allow aligned ontology population are presented and their applicability discussed. The authors present the coverage of HL7 RIM inadequacy for ontology mapping and how to circumvent it, NLP techniques for semi-automated ontology population, and the current trends about knowledge representation and reasoning that concur to the proposed achievement.

The Web

Recently, there has been an increasing interest in formalisms for representing uncertain information on the Semantic Web. This interest is triggered by the observation that knowledge on the web is not always crisp and we have to be able to deal with incomplete, inconsistent and vague information. The treatment of this kind of information requires new approaches for knowledge representation and reasoning on the web as existing Semantic Web languages are based on classical logic which is known to be inadequate for representing uncertainty in many cases. While different general approaches for extending Semantic Web languages with the ability to represent uncertainty are explored, we focus our attention on probabilistic approaches. We survey existing proposals for extending semantic web languages or formalisms underlying Semantic Web languages in terms of their expressive power, reasoning capabilities as well as their suitability for supporting typical tasks associated with the Semantic Web.

After having shifted from Web 1.0 to Web 2.0, scientists welcome the advent of Web 3.0, an environment where meaning is added to data. While in the Semantic Web people are no longer users, but part of the emerging applications, producers, subjects and beneficiaries of the Big Data, however, opaque processing of personal data poses tremendous risks and dangers for individuals. Given the new era of Big Data this paper studies firms’ purposes and practices to detect some emerging privacy risks. Moreover, theories that deal with social networks are examined to conclude that, even if people state that they value their privacy, however, they often disclose a huge volume of personal information. Taking into account that today’s European concept of privacy is conceptualized in negative terms this paper also proposes the implementation of trust and loyalty into the privacy concept through flexible fiduciary laws. Furthermore, data portability is discussed to detect its potential as a strategic feature, a key tool that will enhance trust. Finally, further scenarios and proposals are submitted, in our attempt to answer the question whether the European concept of privacy could be re-shaped for the benefit of individuals.

The Impact

The subject of Information Technology (IT) adoption and use has been going on for some time (Jeyaraj & Sabherwal, 2008). In particular, to electronic commerce (e-Commerce) adoption and use, the invention of Web 2.0 presents new technological features for potential and current e-Commerce adopters as well as new challenges. With Web 2.0, customers' perceptions, preferences and decisions are not only based on information presented on e-Commerce websites, but are also influenced by content generated by people on social networks and interactive e-Commerce websites. This poses the following question: how can Small, Medium and Micro-Sized Enterprises in the tourism sector (tourism SMMEs) keep up with these technological advancements given their limited resources? Accordingly, this book chapter proposes a framework that shows challenges and incentives (critical success factors) of e-Commerce, identifies e-Commerce platforms tourism SMMEs should adopt in order to maximise benefits and outlines what tourism SMMEs should expect from their e-Commerce platforms.

La tecnología del podcasting ha conocido un considerable crecimiento durante estos últimos años, facilitada por circunstancias como la consolidación de la web semántica manual o web 2.0 y el surgimiento de la figura del prosumidor de contenidos. Desde el punto de vista de su evolución en el tiempo consideramos la existencia de cuatro etapas diferenciadas, a las que denominamos como experimental (finales del siglo XX a 2005), de consolidación (2006 a 2009), multimedia (2010 a 2013) y de eclosión (2014 hasta la actualidad). Se analiza cuál es el grado de utilización de los podcasts para el tratamiento de la temática referida a la difusión del patrimonio cultural en el ámbito específico hispanoparlante. Para ello, se ha examinado la presencia de esta clase de herramientas en dos de las principales plataformas de podcasting a escala internacional: iVoox y SoundCloud. Podcasting technology has had a considerable growth during last years, facilitated by circumstances such as the consolidation of the manual semantic web or web 2.0 and the emergence of the figure of the prosumer of contents. From the point of view of its chronological evolution, we consider the existence of four differentiated stages, which we call as experimental (late 20th century to 2005), consolidation (2006 to 2009), multimedia (2010 to 2013) and hatching (2014 to nowadays). We analyze the degree of use of podcasts for the treatment of the theme related to the dissemination of cultural heritage in the specific Hispanic-speaking environment. In order to do so, we have examined the presence of this kind of tools in two of the main international podcasting platforms: iVoox and SoundCloud.

We elaborate on the shifting of decision support systems towards social networking, which is based on the concepts of Web 2.0 and Semantic Web technology. As the characteristics of the relevant components are different from traditional decision support systems, we present necessary adaptations when adopting social networks for decision support within an organization. We also present organizational obstacles when adopting/using such systems and clues to overcome them.

An approach to universal (meta-)logical reasoning in classical higher-order logic is employed to explore and study simplifications of Kurt Gödel's modal ontological argument. Some argument premises are modified, others are dropped, modal collapse is avoided and validity is shown already in weak modal logics K and T. Key to the gained simplifications of Gödel's original theory is the exploitation of a link to the notions of filter and ultrafilter in topology. The paper illustrates how modern knowledge representation and reasoning technology for quantified non-classical logics can contribute new knowledge to other disciplines. The contributed material is also well suited to support teaching of non-trivial logic formalisms in classroom.
