Abstract

The assumptions underlying the Probability Ranking Principle (PRP) have led to a number of alternative approaches that cater or compensate for the PRP's limitations. In this poster we focus on the Interactive PRP (iPRP), which rejects the assumption of independence between documents made by the PRP. Although the theoretical framework of the iPRP is appealing, no instantiation has been proposed and investigated. In this poster, we propose a possible instantiation of the principle, performing the first empirical comparison of the iPRP against the PRP. For document diversification, our results show that the iPRP is significantly better than the PRP, and comparable to or better than other methods such as Modern Portfolio Theory.
用于多样化文档排名的交互式PRP
基于概率排序原则(PRP)的假设导致了许多替代方法,这些方法迎合或弥补了PRP的局限性。在这张海报中,我们将重点放在交互式PRP (iPRP)上,它拒绝假设PRP所制作的文件之间是独立的。虽然iPRP的理论框架很有吸引力,但没有实例被提出和研究。在这张海报中,我们提出了该原则的一个可能的实例,对iPRP和PRP进行了第一次实证比较。对于文件多样化,我们的结果表明iPRP明显优于PRP,并且与现代投资组合理论等其他方法相当或更好。
