MSMARCO传代样本集的灵敏度分析

A Sensitivity Analysis of the MSMARCO Passage Collection

Joel Mackenzie, Matthias Petri, Alistair Moffat

摘要:

最近的MSMARCO通道检索收集允许研究人员开发高度调谐的检索系统。与传统语料库相比,这个数据集的一个特点是,大多数主题只有一个标记为相关的答案。在这里,我们进行了一个“如果”的敏感性研究,询问是否一组系统仍然会有相同的相对性能,如果每个主题的更多的段落被认为是“相关的”,探索几种机制,以确定这样的分类段落集。我们的研究结果表明,在一般情况下,虽然运行分数可以显着变化,如果额外的似是而非的通道被假定为相关的,派生的系统排序是相对不敏感的额外的相关性,提供支持的方法,使用的时候,MSMARCO通过收集创建。

英文摘要:

The recent MSMARCO passage retrieval collection has allowed researchers to develop highly tuned retrieval systems. One aspect of this data set that makes it distinctive compared to traditional corpora is that most of the topics only have a single answer passage marked relevant. Here we carry out a "what if" sensitivity study, asking whether a set of systems would still have the same relative performance if more passages per topic were deemed to be "relevant", exploring several mechanisms for identifying sets of passages to be so categorized. Our results show that, in general, while run scores can vary markedly if additional plausible passages are presumed to be relevant, the derived system ordering is relatively insensitive to additional relevance, providing support for the methodology that was used at the time the MSMARCO passage collection was created.
