Social networks are a popular movement on the web. On the Semantic Web, it is simple to make trust annotations to social relationships. In this paper, we present a two level approach to integrating trust, provenance, and annotations in Semantic Web systems. We describe an algorithm for inferring trust relationships using provenance information and trust annotations in Semantic Web-based social ...

introduction When reflecting the term trust, there are two main hypotheses which can be found in most of the literature: First, trust is presented as an amorphous phenomenon, which is difficult to measure empirically (Endress, 2002). Second, the characteristic of trust is rather fragile. Trust as a mediator of social interactions cannot be quantified precisely, it has to be generated and recrea...

The so-called "Web of Trust" is one of the ultimate goals of the Semantic Web. Research on the topic of trust in this domain has focused largely on digital signatures, certificates, and authentication. At the same time, there is a wealth of research into trust and social networks in the physical world. In this paper, we describe an approach for integrating the two to build a web of trust in a m...

Trust is a necessary concept to realize the Semantic Web. But how can we build a “Web of Trust”? We first argue that a small “Web of Trust” for each community is very essential to realize a huge “Web of Trust.” Then, we focus on an academic community as a microcosm of a “Web of Trust” and show a web mining approach to generate a social network automatically. Each edge is added using the number ...

Trust and distrust are two increasingly important metrics in social networks. Since many of these networks are very large, it is only natural that not all users know each other. To this aim, propagation and aggregation operators are often used to estimate (dis)trust relations for users that are not directly connected through the network. In this paper, we introduce bilattice-based aggregation a...

In this paper, we present a work-in-progress towards a perceptual study concerning male and female first impressions of male virtual faces as variations are made in terms of their facial hair (beard) length, colour and the camera viewing angle. Previous studies involving real human faces suggest that these types of variations may impact impressions of trustworthiness and related qualities, such...

Bases for Trust in Online Social Networks

We report on the first evaluation of the Companions project prototypes. We give preliminary results from our phase one evaluation, using known and well-understood dialogue metrics. We also give a first indication of the directions we plan to take to evaluate increasingly sophisticated conversational systems, using measures of coherence and appropriateness. 12

water resources local governance can is one of the most influential collaborative approach in the water resources management. social monitoring of local stakeholders plays an important role in planning, resources management and water efficient governance. therefore to achieve this goal, social network analysis has been considered as an approach of analysis of the relationship among local stakeh...

The growing importance of online social networks provides fertile ground for researchers seeking to gain a deeper understanding of fundamental constructs of human behavior, such as trust and forgiveness, and their linkage to social ties. Through a field experiment that uses data from the Facebook API to measure social ties that connect our subjects, we separate forward-looking instrumental trus...
