Humans seek information regarding a specific topic through performing a conversation containing a series of questions and answers. In the pursuit of conversational question answering research, we introduce the PCoQA, the first \textbf{P}ersian \textbf{Co}nversational \textbf{Q}uestion \textbf{A}nswering dataset, a resource comprising information-seeking dialogs encompassing a total of 9,026 contextually-driven questions. Each dialog involves a questioner, a responder, and a document from the Wikipedia; The questioner asks several inter-connected questions from the text and the responder provides a span of the document as the answer for each question. PCoQA is designed to present novel challenges compared to previous question answering datasets including having more open-ended non-factual answers, longer answers, and fewer lexical overlaps. This paper not only presents the comprehensive PCoQA dataset but also reports the performance of various benchmark models. Our models include baseline models and pre-trained models, which are leveraged to boost the performance of the model. The dataset and benchmarks are available at our Github page.

通过引入PCoQA数据集，本研究旨在为会话式问答研究提供第一个波斯语会话式问答数据集，包含多达9,026个背景驱动的问题，涉及提问者、回答者和维基百科文档。该数据集对以往问答数据集提供了新的挑战，包括更多开放性非事实性答案、较长答案和更少的词汇重复。本文还介绍了多种基准模型的性能，包括基线模型和预训练模型，并使用预训练模型提升了性能。有关数据集和基准模型可在我们的Github页面上获取。
