摘要

我们提出了一种改进问答系统文档检索的简单方法。该方法使检索系统偏向于包含在其他包含相同类型问题答案的文档中出现过的单词的文档。该方法几乎适用于任何检索系统，并且在强基线上显示出统计上显着的性能改进。

Improving QA retrieval using document priors

We present a simple way to improve document retrieval for question answering systems. The method biases the retrieval system toward documents that contain words that have appeared in other documents containing answers to the same type of question. The method works with virtually any retrieval system, and exhibits a statistically significant performance improvement over a strong baseline.
