1 Background 首先介绍下研究背景,Knowledge Base Question Answering 简称KBQA,他是一个根据自然语言表达的问题,从Knowledge Base中寻找答案的一个任务。传统的解决问题的办法,有基于pipeline的,比如先用ner来提取实体,然后通过entity linking来寻找答案;也有直接端到端的自动提取答案的。 本文要解决的是KBQA中一种偏难...

论文翻译笔记:《Knowledge Base Question Answering via Encoding of Complex Query Graphs》 https:// 语义解析(SP)技术的目标是学习语义解析树或等价查询图1,用于表示问题的语义结构。例如,在图1中,查询图形成树形。答案节点A作为树的根,是表示真实答案实体的可变顶点。焦点节点(US、river、2nd)是从提及的问题中提...

论文解读:Improved Neural Relation Detection for Knowledge Base Question Answering 本文解决KBQA中的子问题——Relation Detection(关系检测)。关系检测目的是给定一个问句,根据知识库来判断该问句目标的关系是什么。例如问句“中国的首都是哪里”,我们会先锁定问句的中心实体(主题词)是“中国”,其次检测这句话...
论文题目: Improving Multi-hop Knowledge Base Question Answering by Learning Intermediate Supervision Signals 链接:https://arxiv.org/abs/2101.03737 摘要 Multi-hop KBQA的目标在于在知识库上找到距离问句中实体若干跳之外的答案实体。主要挑战在于传统KBQA问句集只有问题和最终答案/SPARQL对,缺少中间的监督信息。
