Existing tools for Question Answering (QA) have challenges that limit their
use in practice. They can be complex to set up or integrate with existing
infrastructure, do not offer configurable interactive interfaces, and do not
cover the full set of subtasks that frequently comprise the QA pipeline (query
expansion, retrieval, reading, and explanation/sensemaking). To help address
these issues, we introduce NeuralQA - a usable library for QA on large
datasets. NeuralQA integrates well with existing infrastructure (e.g.,
ElasticSearch instances and reader models trained with the HuggingFace
Transformers API) and offers helpful defaults for QA subtasks. It introduces
and implements contextual query expansion (CQE) using a masked language model
(MLM) as well as relevant snippets (RelSnip) - a method for condensing large
documents into smaller passages that can be speedily processed by a document
reader model. Finally, it offers a flexible user interface to support workflows
for research explorations (e.g., visualization of gradient-based explanations
to support qualitative inspection of model behaviour) and large scale search
deployment. Code and documentation for NeuralQA is available as open source on
Github (this https URL}{Github).

NeuralQA 是一个用于大规模数据集上的 QA 的易于使用的库，它集成了上下文查询扩展 (CQE) 和相关片段 (RelSnip) 来支持 QA 子任务，并提供了灵活的用户界面以支持研究探索和大规模搜索部署。
