Abstract
Communication within Internet auction systems generally takes place without users being in a physical contact or knowing anything of each other. Therefore, they have to rely on mechanisms implemented within these online systems – reputation systems.
Most of such mechanisms are based on the creation of trustworthy environment with the help of additional attributes associated with users and their roles. These attributes are constructed based on previous transactions or recommendations (positive or negative comments regarding such transacations).
The creation of trusts in the online auction environment is the basic element for the functionality of these environments. The suggestion of reputations system which includes also information about other behavior within respective Internet auction is described in our paper.
We will discuss some experiments performed on eBay auction.
