We build two open domain quesiton answering (QA) tasks for Chinese language, one is knowledge-based QA (or KBQA) and the other is document-based QA (or DBQA).
These two open domain QA datasets are used in http://tcci.ccf.org.cn/conference/2016/pages/page05_CFPTasks.html, and are the largest QA datasets for Chinese language.
More details about the datasets can be found in the guideline PDF, and you can also send your questions to [email protected].
