Preferential Reasoning on a Web of Trust [chapter]

Stijn Heymans, Davy Van Nieuwenborgh, Dirk Vermeir
2005 Lecture Notes in Computer Science  
We introduce a framework, based on logic programming, for preferential reasoning with agents on the Semantic Web.  ...  Finally, we show how an agent can learn preferences on call literals if it is part of a web of trusted agents.  ...  Preferential Reasoning on a Web of Trust Often, the user has its particular knowledge, in the form of a program, and a sense of which calls he believes more than other calls, e.g. because (part of) one  ...

Preferential Attachment in an Internet-mediated Human Network [article]

Chezka Camille P. Arevalo, Jaderick P. Pabico
2015 arXiv   pre-print
Based on our analysis, we found out that users of the site exhibit preferential attachment to users with high number of friends.  ...  In the advent of the Internet, web-mediated social networking has become of great influence to Filipinos.  ...  One possible reason is that the availability of accounts in Friendster is becoming less through time, with some of the accounts going private and unreadable to the web robot.  ...

Evaluating architectures for independently auditing service level agreements

Ana Carolina Barbosa, Jacques Sauvé, Walfredo Cirne, Mirna Carelli
2006 Future generations computer systems  
The qualitative evaluation compares the architectures based on aspects such as intrusiveness, trust, use of extra requests, possibility of preferential treatment, possibility of auditing consumer load,  ...  For such an integration to be effective, the provider and the consumer of a service must negotiate a service level agreement (SLA), i.e. a contract that specifies what one party can expect from the other  ...  Thanks also to the anonymous reviewers who greatly helped to improve the quality and presentation of the paper.  ...

The Emergence of Opinion Leaders in Online Review Communities

Yingda Lu, Kinshuk Jerath, Param Vir Singh

Multicriteria Subjective Reputation Management Model [chapter]

Michał Majdan, Włodzimierz Ogryczak
2010 Lecture Notes in Computer Science  
In this paper a new reputation management model is presented. It is focused on aggregation of community wide reputation in situation when agents do not share the same preference structure.  ...  The expressive power of subjective utilities concept along with the WOWA aggregation technique provides the reputation management system with a capability to model various preference structures.  ...  Acknowledgements This work has been partially supported by the Polish Ministry of Science and Higher Education under the research grant N N516 4307 33.  ...

Growing a Web of Trust

Benjamin Schiller, Thorsten Strufe, Dirk Kohlweyer, Jan Seedorf
2015 2015 IEEE 40th Conference on Local Computer Networks (LCN)  
New edges are formed based on realistic assumptions about trust establishment. We analyze the growth of a real-world WoT and perform a parameter study of our model.  ...  Web of Trust (WoT) graphs represent trust relations between people. They are used for research and analysis in various domains. Real-world instances are only available in sizes of up to 55k vertices.  ...  INTRODUCTION Trust between users of a system is often represented by a trust graph called a Web of Trust (WoT).  ...

Link Prediction in Complex Networks by Multi Degree Preferential-Attachment Indices [article]

Ke Hu, Ju Xiang, Wanchun Yang, Xiaoke Xu, Yi Tang
2012 arXiv   pre-print
By revisiting the preferential attachment mechanism for generating a scale-free network, here we propose a class of preferential attachment indices which are different from the previous one.  ...  In principle, the rules of links formation of a network model can be considered as a kind of link prediction algorithm.  ...  All the trust relationships interact and form the Web of Trust which is then combined with review ratings to determine which reviews are shown to the user. 12) Slashdot Social network(SS) [40] : Slashdot  ...

How placing limitations on the size of personal networks changes the structural properties of complex networks

Somayeh Koohborfardhaghighi, Jörn Altmann
2014 Proceedings of the 23rd International Conference on World Wide Web - WWW '14 Companion  
Despite the fact that technology has shrunk our world, there is also a limit to how many close friends one can keep and count on. It is a relatively small number.  ...  the structural properties of a complex network, in this paper, we focus on another factor that may contribute to such changes, namely the size of personal networks.  ...  Instead of writing down names immediately, you ask about the context in which trust should be considered. The reason is that trust is a context specific issue.  ...
