Many existing reputation systems sharply divide the trust value into right or wrong, thus ignoring another core dimension of trust: uncertainty. As uncertainty deeply impacts a node’s anticipation of others’ behavior and decisions during interaction. Besides lacking a precise semantic, this information has abstracted away any notion of time. This approach is objective and robust. But, this appr...

Cloud Computing refers to applications delivered as services over the internet, and the datacenters that provide those services with hardware and systems software. These were earlier referred to as Software as a Service (SaaS). Scheduling is justified by job components (called tasks), lack of information. In fact, in a large fraction of jobs from machine learning, bio-computing, and image proce...

This article pursues two tasks. The first is to clarify the value and productivity of Williams’s Keywords: a vocabulary culture society (first edition 1976, second expanded 1983a) for project Cultural Studies. clarification helped, I argue, by reading it alongside Vološinov’s Marxism philosophy language (published in Russian 1929, translated into English 1973). related task speculative developm...

A serious problem on the WWW is finding reliable information. Not everything found on the Web is true and the Semantic Web does not change that in any way. The problem will be even more crucial for the Semantic Web, where agents will be integrating and using information from multiple sources. Thus, if an incorrect premise is used due to a single faulty source, then any conclusions drawn may be ...

Lack of trust in autonomy is a recurrent issue that is becoming more and more acute as manpower reduction pressures increase. We address the socio-technical form of this trust problem through a novel decision explanation approach. Our approach employs a semantic representation to capture decision-relevant concepts as well as other mission-relevant knowledge along with a reasoning approach that ...

Maintaining trust among peer-to-peer systems is a problem, Open nature of peer-to-peer systems exposes them to malicious activity. Building trust relationships among peers can mitigate attacks of malicious peers. This paper presents an automated trust model which takes into consideration peers past interaction and recommendations to choose trustworthy peer. While evaluating trustworthiness para...

Efficient defense against security attacks is a challenging task in the wireless sensor network environment. Due to their infrastructure-less operation and the limited node and network resources, the applicability of legacy security solutions is disputable. The situation is further aggravated as the next generation wireless sensor network become larger and larger. To cope with the network dimen...

Trust is essential for further and wider acceptance of contemporary e-services. It was first addressed almost thirty years ago in Trusted Computer System Evaluation Criteria standard by the US DoD. But this and other proposed approaches of that period were actually solving security. Roughly some ten years ago, methodologies followed that addressed trust phenomenon at its core, and they were bas...
