问答是信息检索的一个子领域。这是一项回答以自然语言发布的问题的任务。问答系统(QAS)可以被认为是返回一组相关文档的搜索引擎的一个很好的替代方案。问答系统由三个主要模块组成：问题分析、段落检索和答案提取。多年来，已经有许多QASS被用于不同的语言。然而，由于语言方面的挑战以及研究人员缺乏可用的资源和工具，阿拉伯语QASS的发展受到了拖累。在这次调查中，我们从语言带来的挑战开始，以及这些挑战如何使新的阿拉伯语QA的发展变得更加困难。接下来，我们对几个阿拉伯语卡斯做一个详细的回顾。然后深入分析了QAS的三个模块中的技术和方法。我们提出了一个重要的和最近开发的工具，以帮助这一领域的研究人员的概述。我们还介绍了可用的阿拉伯语和多语种数据集，并介绍了用于评估QASS的不同衡量标准。最后，基于目前为其他语言的问答而开发的最先进的技术，调查深入探讨了阿拉伯语问答系统的未来发展方向。
Question answering is a subfield of information retrieval. It is a task of answering a question posted in a natural language. A question answering system (QAS) may be considered a good alternative to search engines that return a set of related documents. The QAS system is composed of three main modules; question analysis, passage retrieval, and answer extraction. Over the years, numerous QASs have been presented for use in different languages. However, the the development of Arabic QASs has been slowed by linguistic challenges and the lack of resources and tools available to researchers. In this survey, we start with the challenges due to the language and how these challenges make the development of new Arabic QAS more difficult. Next, we do a detailed review of several Arabic QASs. This is followed by an in-depth analysis of the techniques and approaches in the three modules of a QAS. We present an overview of important and recent tools that were developed to help the researchers in this field. We also cover the available Arabic and multilingual datasets, and a look at the different measures used to assess QASs. Finally, the survey delves into the future direction of Arabic QAS systems based on the current state-of-the-art techniques developed for question answering in other languages.
