论文摘要
我们介绍了关于多语言信息访问（MIA）2022共享任务的研讨会的结果，评估了16种类型上多样性的语言中的跨语性开放回答问题答案（QA）系统。在此任务中，我们在14种类型上多样化的语言中调整了两个大规模的跨语义开放式QA数据集，并使用了2种代表性不足的语言中的新注释的开放式QA数据：Tagalog和Tamil。四个团队提交了他们的系统。利用迭代开采的最佳系统是不同的负面示例和较大的预审慎模型的实现32.2 F1，表现优于我们的基线4.5分。第二最佳系统使用实体感知的上下文化表示文档检索，并在泰米尔语（20.8 F1）方面取得了重大改进，而其他大多数系统的得分几乎为零。
We present the results of the Workshop on Multilingual Information Access (MIA) 2022 Shared Task, evaluating cross-lingual open-retrieval question answering (QA) systems in 16 typologically diverse languages. In this task, we adapted two large-scale cross-lingual open-retrieval QA datasets in 14 typologically diverse languages, and newly annotated open-retrieval QA data in 2 underrepresented languages: Tagalog and Tamil. Four teams submitted their systems. The best system leveraging iteratively mined diverse negative examples and larger pretrained models achieves 32.2 F1, outperforming our baseline by 4.5 points. The second best system uses entity-aware contextualized representations for document retrieval, and achieves significant improvements in Tamil (20.8 F1), whereas most of the other systems yield nearly zero scores.
