Trusting any information on web is psychosomatic and subliminal by nature. The decision is left on the requestor to assess, judge and corroborate the contents contained in the websites before perceiving it. This is of acute concern when websites deal with sensitive issues like health. There is no standard mechanism that embodies or characterizes how to make these ‘trust’ decisions. Although all...

Despite the fact that online communities (OCs) enjoy a growing number of members, their success is regularly impaired by infringements of user trust by either the community operator or other users. Since previous research studies have focused their investigation of the effects of single IT factors on user trust and participation in OCs, the field lacks an integrative view on how a comprehensive...

Reciprocal feedback distorts the production and content of reputation information, hampering trust and trade efficiency. Data from eBay and other sources combined with laboratory data provide a robust picture of how reciprocity can be guided by changes in the way feedback information flows through the system, leading to more accurate reputation information, more trust and more efficient trade.

The Internet is increasingly being used as a means to search and communicate health information. As the mission of Health on the Net Foundation (HON) is to guide healthcare consumers and professionals to trustworthy online information, we have been interested in seeing the trend of the attitudes towards Internet use for health purposes since 1996. This article presents the results of the 10<sup...

We present an experimental mechanism for enriching web content with quality metadata. This mechanism is based on a simple and well-known initiative in the field of the health-related web, the HONcode. The Resource Description Framework (RDF) format and the Dublin Core Metadata Element Set were used to formalize these metadata. The model of trust proposed is based on a quality model for health-r...

The proliferation of misleading information in everyday access media outlets such as social media feeds, news blogs, and online newspapers have made it challenging to identify trustworthy news sources, thus increasing the need for computational tools able to provide insights into the reliability of online content. In this paper, we focus on the automatic identification of fake content in online...

Several content based image retrieval systems use region-based descriptors of salient regions to represent the image content. In this application domain, no perfect pixel wise segmentation is required, but instead, a stable and unsupervised extraction of salient region-descriptors is needed which might be generally applicable. Accordingly, in this paper an algorithm is proposed which combines l...

Trust is crucial for mobile communications. However, how to manage trust in mobile enterprise networking among various mobile devices is problematic for companies using mobile enterprise solutions. This paper presents a trust management system in an enterprise’s virtual private networks (VPN). The system supports confidential content management and overcomes the diversity support of security in...

Traditional access control models are often found to be inadequate for digital libraries. This is because the user population for digital libraries is very dynamic and not completely known in advance. In addition, the objects stored in a digital library are characterized by fine-grained behavioral interfaces and highly-contextualized access restrictions that require a user’s access privileges t...
