任务描述

CCKS2020:新冠知识图谱问答评测。竞赛地址:https://biendata.com/competition/ccks_2020_7_4/

这个竞赛属于中文知识图谱自然语言问答任务(CKBQA),即输入一句中文问题,问答系统从给定知识库中选择若干实体或属性值作为该问题的答案。竞赛中的问题均为客观事实型,不包含主观因素。理解并回答问题的过程中需要进行实体识别、关系抽取、语义解析等子任务。

竞赛任务所使用的新冠开放知识图谱来源于 OpenKG 的新冠专题(http://openkg.cn/group/coronavirus),此外还包括开放领域知识库PKUBASE一起作为问答任务的依据。
