This experimental study tested the knowledge gap hypothesis at the intersection of audience education levels and news formats (newspaper versus online). The findings reveal a gap in public affairs knowledge acquisition between South Korean citizens (N=123) from different educational backgrounds. Moreover, the high education group comprehended news with the same level of efficiency across online...

It seems that facilitating conditions for knowledge sharing, like a shared understanding, a common language as well as the multifold and direct relations between are idiosyncrasies of a knowledge network. However, these facilitating conditions are limited if a high turn over rate is involved in a knowledge network. As a consequence, capability differences between knowledge network members will ...

In this paper we propose an epistemic concept language, where the epistemic operator is interpreted in terms of minimal knowledge. We show that the proposed formalism provides an adequate characterization of many non-rst-order aspects of frame-based knowledge representation systems, by admitting in the knowledge base various forms of epistemic sentences. In particular, we address the formalizat...

This paper addresses cooperative operation of symbiotic human-robot system. In order to implement cooperative operation, symbiotic human-robot system is modeled using frame-based knowledge representation. According to this knowledge model, the system is defined in the Software Platform of Agents and Knowledge Management (SPAK). With the support of SPAK, cooperative operation can be therefore ca...

Using ontology data model to accurately represent Al-Quran knowledge using its inherent structure of Division (Juz), Chapter (Surah), and Verse (Ayah) should be done within the framework Islamic Knowledge Management (IKM). Data modelling neglecting IKM would result in inaccuracy irrelevant processing activities involving Al-Quran. Many current approaches utilizing conventional management method...

In knowledge engineering, modelling knowledge is the process of structuring knowledge before implementation. A crucial part of system development depends on the acquiring and structuring, since the quality of system’s contents is of decisive importance for making good decisions. Models are needed to assure that all the required knowledge is present. However, the current models tend to be large ...

This paper describes a knowledge model for a configuration problem in the domain of traffic control. The goal of this model is to help traffic engineers in the dynamic selection of a set of messages to be presented to drivers on variable message signals. This selection is done in a real-time context using data recorded by traffic detectors on motorways. The system follows an advanced knowledge-...

Argumentative formalisms have been widely recognized as knowledge representation and reasoning tools able to deal with incomplete and potentially contradictory information. All such formalisms are computationally demanding. Hence, optimizing argumentative systems has been approached from di®erent views. We have developed a new proposal to solve the aforementioned problem. The key to our approac...

Knowledge ‘decay’ is a measure of the degradation of knowledge integrity. In a unified knowledge representation, data, information and knowledge are all represented in a single formalism as “items”. A unified knowledge representation is extended here to include two measures of knowledge integrity. A rule of inference is defined on the unified knowledge representation that preserves the validity...
