Masao Kobayashi, Takayuki Ito (Nagoya Inst. of Tech.) AI2009-9
Abstract (in Japanese) (See Japanese page) 
(in English) Internet auction is one of the most important ways for real commerce. Most auction sites employ simple reputation systems. However, the existing evaluation mechanism has some problems mechanism. In this study, we propose an evaluation system based on user’s relationships in Internet auction.
In this paper, we show evaluation techniques in our system and examine relationships between users with actual transaction data in an Internet auction site. The results showed evaluation for users based on Relationships values correlate with an existing direct rating in user’s rankings. In addition, the evaluation based on Relationships values rank users lower than the existing ways.
