举个例子,对于KG三元组{title:“Apple”,relation:“价格上涨”,object:“10%”},如果没有额外的上下文,很难确定出实体”Apple“指的是水果还是公司,除此之外,StructQA 将提取的 KG 三元组和原始文本作为 LLM 的输入,导致Prompt明显变长和信息冗余。 为此,本文作者提出了HOLMES方法,该方法创建一个以查询为中心...
1、CommonsenseQA基准上各种模型的开发精度和测试精度。 2、在OpenbookQA基准上开发和测试各种模型性能的准确性。 3、从问题节点到候选答案节点的完整推理链。 其中蓝色节点是问题实体节点,红色和绿色节点是候选答案节点。较粗的边缘表示与邻域节点的相关性得分较高,而较细的边缘表示较低的得分。左侧...
受基于知识库QA任务以及提取知识路径技术启发,原文作者在基准模型基础上提出一种改进模型,为模型添加外部知识库。具体实现上,原文作者提出一种新颖的知识路径提取算法以及必要和可选的信息单元(Necessary and Optional Information Cell ,NOIC),可以从知识库中提取有效合理的背景知识,使模型在文档上下文推理的多跳之间插入...
Decomposing Complex Questions Makes Multi-Hop QA Easier and More Interpretable.Ruiliu FuHan WangXuejun ZhangJun ZhouYonghong YanAssociation for Computational LinguisticsEmpirical Methods in Natural Language Processing
WebQA includes a secondary text-only QA task to ensure improved visual performance does not come at the cost of language understanding. Our challenge for the community is to create unified multimodal reasoning models that answer questions regardless of the source modality, moving us closer to ...
We propose an approach for zero- and few-shot re-ranking of multi-hop document paths for open-domain QA. PromptRank constructs a prompt that consists of(i) an instructionand(ii) the pathand uses an LLM to score paths as probability of generating the question given the prompt. ...
Grounded Multi-Hop VideoQA in Long-Form Egocentric Videos This paper considers the problem of Multi-Hop Video Question Answering (MH-VidQA) in long-form egocentric videos. This task not only requires to answer visual questions, but also to localize multiple relevant time intervals within the ...
Multihop是一种通过多个中间节点转发数据以实现远距离通信的网络技术,广泛应用于无线Ad Hoc、传感器网络等场景,其核心价值在于扩大覆盖范围并提升网络灵活性,但也面临延迟增加和路由复杂度提升等挑战。以下从概念、应用、优缺点及必要性等维度展开分析。 一、Multihop的核心机制 Multihop技术通过中间...
目前解决复杂KBQA(Knowledge Base Question Answering)的难点主要在于:问题带限制以及问题里包含有多个关系。这篇文章提出了一个query graph生成方法解决这个问题。 1. 背景介绍 在了解本文具体做什么之前,需要再明确下什么是带限制的问题和multi-hop of relations。带限制的问题,其实就是带限定词,例如Who was the firs...
Our dataset is created by utilizing three existing multi-hop datasets: HotpotQA, 2WikiMultihopQA, and MuSiQue. Instead of relying solely on factual reasoning, we enhance the existing multi-hop questions by adding another layer of questioning that involves one, two, or all three of the ...
