摘要:

诸如开放域问答、事实检查、槽填充和实体链接之类的测试问题需要访问大量的外部知识源。虽然一些模型在个别任务上表现良好,但开发通用模型是困难的,因为除了专用的基础设施之外,每个任务可能需要对自定义知识源进行计算昂贵的索引。为了促进对大型文本资源中特定信息的模型的研究,我们提出了一个知识密集型语言任务(KILT)的基准。KILT中的所有任务都基于维基百科的同一快照,通过重用组件减少了工程周转,并加速了对任务无关内存架构的研究。我们测试特定任务和一般基线,评估下游性能以及模型提供出处的能力。我们发现,一个共享的密集矢量索引加上seq2seq模型是一个强大的基线,优于更多的量身定制的方法,事实检查,开放域问答和对话,并产生竞争力的结果,实体链接和插槽填充,通过生成消歧文本。KILT数据和代码可在https://github.com/facebookresearch/KILT上获得。

英文摘要:

Challenging problems such as open-domain question answering, fact checking, slot filling and entity linking require access to large, external knowledge sources. While some models do well on individual tasks, developing general models is difficult as each task might require computationally expensive indexing of custom knowledge sources, in addition to dedicated infrastructure. To catalyze research on models that condition on specific information in large textual resources, we present a benchmark for knowledge-intensive language tasks (KILT). All tasks in KILT are grounded in the same snapshot of Wikipedia, reducing engineering turnaround through the re-use of components, as well as accelerating research into task-agnostic memory architectures. We test both task-specific and general baselines, evaluating downstream performance in addition to the ability of the models to provide provenance. We find that a shared dense vector index coupled with a seq2seq model is a strong baseline, outperforming more tailor-made approaches for fact checking, open-domain question answering and dialogue, and yielding competitive results on entity linking and slot filling, by generating disambiguated text. KILT data and code are available at https://github.com/facebookresearch/KILT.
