在本文中,我们探讨了检索模型使用的术语加权方案的偏差。在这里,我们将偏差视为检索模型由于文档内部和有关文档的特征而过度偏向某些文档而不是其他文档的程度。我们着手寻找偏差最小的检索模型/权重。这主要是由于最近提出了一套基于独立分歧 (DFI) 框架的新检索模型。据称,此类模型提供了最公平的术语权重,因为它们不对术语分布做出假设(与大多数其他检索模型不同)。在本文中,我们实证检验公平是否与绩效相关并回答这个问题;越公平越好吗?
In this paper, we explore the bias of term weighting schemes used by retrieval models. Here, we consider bias as the extent to which a retrieval model unduly favours certain documents over others because of characteristics within and about the document. We set out to find the least biased retrieval model/weighting. This is largely motivated by the recent proposal of a new suite of retrieval models based on the Divergence From Independence (DFI) framework. The claim is that such models provide the fairest term weighting because they do not make assumptions about the term distribution (unlike most other retrieval models). In this paper, we empirically examine whether fairness is linked to performance and answer the question; is fairer better?
