摘要:

如何对网页、科学家和在线资源进行排名,最近吸引了物理学家和计算机科学家越来越多的关注。本文研究了用户通过离散评分对对象进行投票的评分系统的排序问题。我们提出了一种算法,可以同时评估用户信誉和对象质量的迭代细化的方式。根据人工生成的数据和MovieLens和Amazon的真实数据,我们的算法可以大大提高排名的准确性。这项工作突出了声誉系统在互联网时代的重要性,并指出了一种方法来评估和比较不同的声誉系统的性能。

英文摘要:

How to rank web pages, scientists and online resources has recently attracted increasing attention from both physicists and computer scientists. In this paper, we study the ranking problem of rating systems where users vote objects by discrete ratings. We propose an algorithm that can simultaneously evaluate the user reputation and object quality in an iterative refinement way. According to both the artificially generated data and the real data from MovieLens and Amazon, our algorithm can considerably enhance the ranking accuracy. This work highlights the significance of reputation systems in the Internet era and points out a way to evaluate and compare the performances of different reputation systems.
