ProtoTrust: An Environment for Improved Trust Management in Internet
Auctions
Local Proceedings of 13th East-European Conference, ADBIS 2009, page 385-398. JUMI Pubbbblishing House Ltd., (2009)Abstract
Internet auctions are used everyday by millions.
However, despite frequent criticism, only the most simple
reputation systems are used by the most popular Internet auctions
today.
As a consequence of this, an experienced auction user is forced to
undergo the menial
task of reading and judging comments about his potential transaction
partners.
While it is true that the human mind is the best possible method of
evaluating this information,
the task is time-consuming and error-prone:
the sheer number of comments is sometimes an obstacle to making a
good decision under uncertainty.
Our goal has been the improvement of trust management algorithms for
Internet auction users.
The algorithms themselves are part of a library of trust management
tools developed in the uTrust project. We have designed an extension
for a
popular Web Browser that gives users easy access to our algorithms.
Using the extension users can input their preferences into our Trust
Management
system and select the accuracy they want to obtain.
