TREC稳健检索跟踪探索了通过关注表现不佳的主题来提高检索技术的一致性的方法。赛道中的检索任务是一种传统的特别检索任务，其中评估方法强调系统最无效的主题。2005年版的轨道使用了50个主题，这些主题在一个文档集上被证明是困难的，并在另一个文档集上运行这些主题。如果需要，可以在产生对第二集合的查询时利用来自第一集合的相关性信息。与前几年一样，最有效的检索策略是使用从更多语料库派生的术语来扩展查询。主题的相对难度在两个文档集中有所不同。
The TREC robust retrieval track explores methods for improving the consistency of retrieval technology by focusing on poorly performing topics. The retrieval task in the track is a traditional ad hoc retrieval task where the evaluation methodology emphasizes a system's least effective topics. The 2005 edition of the track used 50 topics that had been demonstrated to be difficult on one document collection, and ran those topics on a different document collection. Relevance information from the first collection could be exploited in producing a query for the second collection, if desired. As in previous years, the most effective retrieval strategy was to expand queries using terms derived from additional corpora. The relative difficulty of topics differed across the two document sets.
