The appearance and continuous growth of virtual communities on the web imposes the challenge of coping with the large amount of information and knowledge these communities produce. The Semantic Web with its set of standards and technologies provides the basic…

Current theories of physics cognition require specification of complex mechanisms for explaining knowledge acquisition. I demonstrate that a quantitative model of physics perception can be constructed by assuming that physics problem perception provides an optimal summary of a set of…

This paper focuses on the role of food tourism in delivering sustainability agendas by examining how the agriculture and tourism sectors have struggled to realise measurable successes because of constraints, conflicting ambitions and low levels of social capital. It focuses…

Malaria is the most important parasite species of humans, affecting more than 2.2 billion people, and causing hundreds of millions of clinical cases and around one million deaths every year. Since the 1940s, mass-produced, inexpensive drugs have been available that…

Attempts to recognize ‘information’ as an asset have led to an increased awareness of why and how this invisible valuable resource does not appear in the financial statements. This paper aims to develop a model based on three-circled sets of…

This study attempts to conceptualise the right to forget/be forgotten along with building a theoretical foundation of this individual’s right and validating the social importance of establishing the right, which is characterised as a nearly fundamental human right to protect…

The Semantic Web attempts to reach a state in the future where everything on the Web will no longer be only machine-readable, but also machine-understandable. An ontology is an explicit specification of a conceptualization. A conceptualization is an abstract, simplified…

Collaborative systems are becoming a widely used tool particularly among professional communities and research groups. They provide a suitable context for distributed people working on the same subject to concentrate their work in a shared place to which everyone has…

In this paper, we present an approach to student's evaluation in a well-defined domain based on a semantic network. A similarity matrix based on the semantic memory structure of humans is used to build a semantic distance model in order…

In this work we analyze the problem of knowledge representation in a collaborative multi-agent system where agents can obtain new information from others through communication. Namely, we analyze several approaches of belief revision in multi-agent systems. We will describe different…
