摘要

鉴于信息检索的实验性质，进展关键取决于分析现有检索方法所产生的错误并了解其局限性。我们的研究探讨了TREC-8特别任务中困难主题的各种假设原因，并表明糟糕的性能部分是由于存在高度分散注意力的子集合，这些子集合可以支配整体性能。

Error analysis of difficult TREC topics

Given the experimental nature of information retrieval, progress critically depends on analyzing the errors made by existing retrieval approaches and understanding their limitations. Our research explores various hypothesized reasons for hard topics in TREC-8 ad hoc task, and shows that the bad performance is partially due to the existence of highly distracting sub-collections that can dominate the overall performance.
